      Hi Fred
       
      I was more amused than critical by the guy making the repair offer, although I'm still very sure my conclusions were correct, but if folks were willing to pay and, as you say, no doubt happy with the result, then good luck to him.
       
      What made me smile was that by the time that post appeared in July 2005 Patrick's software, Peter Mahy's BackPCR, and other similar programs, had been available for 5 or 6 years, with the PCR1000 actually on the verge of being discontinued, so you'd think by then anyone on a PCR1000 user group in particular, which is where it appeared, would be well aware of the possibility and also of how to deal with it:-)
       
      He does go on to list likely symptoms of a corrupt EEPROM, and from that it would seem that calibration issues such as yours, and in varying degrees of severity, were probably much more common than what might be considered total failure.
       
      However, what I remember from the time this problem was first identified suggests that some "crashes" could indeed be just that, resulting in a receiver much less functional than yours was. I don't recall hearing of any that were beyond recovery but perhaps these extreme cases did require the full factory calibration.
       
      I presume the possibility of greater damage lies in those "RESERVED" locations, but I certainly lack the courage to suck it and see:-)

      Yes, the BBC Nanci Griffith version of the song is a favourite I viewed again recently and somehow paraphrasing the title seemed apt.   But we have to bear in mind that the suspicion is pure conjecture without access to fact and those whose receivers were resurrected no doubt thought 50 euros very reasonable for the result.

      That my EEPROM content was so close to "crashed" yet remained working begs the question of what locations and values would would have totally disabled the receiver?  And could that happening inhibit restoring content from a backup?  My feeling is that the EEPROM could be scrambled yet the receiver remain viable to some degree. 

      But I daren't test that idea!

      That's a great paraphrase:-)
       
      All the more so because "having a good old blether" is one of my wife's favourite expressions and/or pastimes, although I suspect she'd prefer the Nanci Griffith's version of the song:-)
       
      I'm pretty sure there wouldn't have been any expensive test gear or a copy of EX2099 within a million miles, what they actually offered was....
       
      "We include original & repaired eeprom on floppy/cdrom, and tuner alignment of the receiver is included in the service"
       
      Which to me sounds very much like....
       
      "We'll use Patrick's software to read your EEPROM data, replace it with his set of average data, and send you a copy of both, plus we'll also use his FFT option to adjust your reference crystal frequency, and that'll be 50 euro and thank you kindly sir" :-)
       
      I could never understand why the price took such a leap, if the set had already been discontinued and that was the resulting speculative price from Ebay sellers etc it might have made a bit more sense, something like the silly prices again that the unlocked sets were fetching, but to double the retail price overnight was certainly an "interesting" marketing technique.

      Yes suspicious considering the required test equipment, experience and time involved.  Applying Icom's (leaked?) alignment program and procedure would be an unusual bargain if 50 Euros (even in 2005).  I remember PCR1000s took a huge leap in price (doubled?) toward the end of manufacture and it's now become a classic used bargain.  The instant I acquire another, first task....backup!!

      And thanks to Alan's original post, I have / we have experienced the ongoing worth of Patrick's efforts.

      Hi Patrick
       
      I'd say it was pretty damn good:-)
       
      Having the average data set was, and is, one heck of a bonus for anyone with a corrupt EEPROM who hasn't backed it up beforehand, but given that the original data from any PCR1000 is the specific alignment data for that particular radio taking a backup to start with is always going to be the best option.
       
      With my first receiver I was very careful to back up the EEPROM once the option became available but must admit to becoming complacent with this one, I've had it for nearly a year and didn't even think about backing it up before the recent question about the manual, but Fred's experience has certainly shown the need is as strong as ever, especially if trying out different software options.
       
      In my recent searches I came across a 2005 post to the group from Spain offering corrupt EEPROM repair plus "tuner alignment" for 50 Euro plus postage. They claimed over 30 sets had already been repaired. It sounds like somebody might have been putting your software to very profitable use:-)

      Hi Nigel,

      Too right about backing up.
      As a long term believer I back up anything needing backing up.
      Then I backup up the backed-up backup! :-)

      The EEPROM content was saved as soon as I became aware of BACKPCR around June 1996 and several further backups since may indicate when the data became corrupted.  I go through phases of interest in listening and it may well have resulted from experimenting recently with PCR1000 programs that mainly didn't run well on Puppy Linux and Wine on a flash drive.

      Following your link and interpretation credibly explains why my PCR1000 showed no dramatic change in performance.   Bandscope and S meter sensitivity were reduced but not greatly, I didn't observe odd AFC problems and operation was not obviously impaired.  I suspect that if my "crashed" EPROM content were loaded to another PCR1000 the result could be similar.

      What I now observe is that Bandscope amplitude is increased by perhaps a third, indicated signal strength is a couple of S points higher on favourite local broadcast stations and displayed frequency accuracy is within a few hertz of zerobeat on USB/LSB.

      So far, so good :-)

      Fred.

      Hi Fred
       
      That certainly looks a lot closer to Patrick's average data, just as well you took the earlier backup, I wonder what caused it to change so much.
       
      It's certainly a warning to all of us that backing up the EEPROM still isn't something to be ignored and I'm feeling much more at ease knowing I've done mine.
       
      I was doing a bit more searching todfay and came across this page........
       
       
      There's some reports on there that show EEPROM results from 14 different PCR1000s and also a calculated average for each location, which are encouragingly similar to Patrick's average values:-)
       
      There's also the indication I was looking for of what each location represents and whilst some are just shown as "reserved", most seem to be reference levels for the S meter and band pass filter tuning points which might explain why a receiver showing very close to the crash pattern, as yours was, could still appear fully functional if nothing more critical had been affected.

      My receiver serial number is in the 02300 range so would be concurrent with when you wrote your program.  It's encouraging that it has proved reliable over 10 years or more.  If being developed and you had been looking for feedback I would have suggested that content and frequency adjustment should not begin without warnings.

      Can you clarify your meaning of "crashed", what the "smart set" is, the simplest way possible to "adjust the frequency" and is the above what the pattern typically becomes?

      Meantime, I'll search for an EEPROM backup done with another program and see if/how it differs.  Hopefulluy any corruption occurred after I made that backup.
      It is interesting that in gereral usage nothing indicated any strangenesses until today!

      Regards,

      Fred.

      I remember there was a pattern for the crashed PCR1000,
      I wonder how your receiver works well if it has the values so identical to the crashed pattern? it's very weird...

      Of course all my statistical model was based on the early production units, I really do not know if things changed on the memory mappings; but it is still weird how close to the crashed pattern your values are...

      you could very well apply the "smart set" of course you need to adjust the frequency as that parameter had very high deviation. Then if you do not like it you can restore your values from your back-up. I did it million times on my unit and I never crashed it once.

      I have a pretty good record of more than 10 years with no-one telling me that crashed his box because of my soft ;-)))

      Completing a bit the story, yes the initial mod was a comparing the different PCBs. The only difference were some surface mounted "resistors" operating as switches giving a hardware configuration. Next some Icom internal software leaked and the rest was easy... ;-)

      Best,
      Pat

      Thanks Patrick,
      I sometimes more enjoy getting things to work too :-)
      Never had cause to fix my PCR1000 but followed temptation, installed and ran your program, backed up and compared the EEPROM successfully.

      However, I was surprised that the EEPROM Analysis showed Crashed Pattern Matching = 99%, Values Out of Statistical Margins = 93%, Reference Frecuency Value = 128. 
      Following the "Advice: Your EEPROM shows the Crash Pattern, please apply an Smart Set Average Data" resulted in the EEPROM content being modified without warning and "Ref. Xtal Freq. Adj." required.

      I then decided to exit, play safe and restored the EEPROM content to original.

      The radio appears to operate as before but would you know if anything might have changed that I should consider?
      Also, would the program be valid for later serial number PCR1000s as well as earlier (like mine)? 

      Regards,

      Fred.

      It takes talent to write such a program and PCR1000BUR looks intriguing.
      Especially the implication of Nigel's observation about setting the "country code". 
      Does this mean that after backing up a cellular blocked US version PCR1000, if the country code is changed then the EEPROM contents restored, unrestricted frequency coverage becomes possible?

      Hi
      I wrote PCR1000BUR some time ago;
      yes the info on how to use it is within the program.
      I remember the default parameters where taken from the statistic gathered from people's backup files.
      There's only one parameter (frequency offset) that presented a huge dispersion then setting that from a default set of values will sure lead to problems.
      For fixing that parameter the program included a module of FFT that help you to quickly and accurately calibrate the receiver frequency when tuning a standard frequency from a couple of satellites,... I'm pulling this out of my memory, everything is well explained within the software.

      Best,
      Patrick
       
      PC1000BUR was/is a program writtten by Patrick Masotta for backing up and restoring the EEPROM calibration data in the PCR1000 to allow a corrupted EEPROM to be restored without needing to send the radio back to Icom.
       
      It also allowed some EEPROM parameters to be edited and recalibrated.
       
      In order to refresh my memory I've just installed my copy of PCR1000BUR 1v2 and as I suspected there is a help file/manual built into the program.
       
      There were other Backup/Restore programs, one at least of which came with a default EEPROM data file as a sort of "Get out of jail free card" for those who didn't have a backup of their own data, but I don't seem to have copies of any of these anymore.
       
      There's a copy of PCR1000BUR 1v2 in the group files section. It's not the copy I installed so can't vouch for it but I'm sure it will be ok.
      The software won't run if it doesn't find a PCR1000 to connect to, not even to allow the manual to be read.
       
      I do remember now using this software before when I had my first PCR1000 and I've just used it to make an EEPROM backup of my current receiver, which is a very quick and easy process.
      I generally use Icom's own control software, and Icom always insisted, in the past anyway, that an EEPROM could only become corrupted through using third party software, well the would wouldn't they:-), but there's no harm in having some insurance.
       
      As an extra "bonus" I see from the manual that there's also an option to specify the "country code" when reinstalling the data so a possible instant coverage upgrade for some:-)

        What made me smile was that by the time that post appeared in July 2005 Patrick's software, Peter Mahy's BackPCR, and other similar programs, had been available for 5 or 6 years, with the PCR1000 actually on the verge of being discontinued, so you'd think by then anyone on a PCR1000 user group in particular, which is where it appeared, would be well aware of the possibility and also of how to deal with it:-)
         
        He does go on to list likely symptoms of a corrupt EEPROM, and from that it would seem that calibration issues such as yours, and in varying degrees of severity, were probably much more common than what might be considered total failure.
         
        However, what I remember from the time this problem was first identified suggests that some "crashes" could indeed be just that, resulting in a receiver much less functional than yours was. I don't recall hearing of any that were beyond recovery but perhaps these extreme cases did require the full factory calibration.
         
        I presume the possibility of greater damage lies in those "RESERVED" locations, but I certainly lack the courage to suck it and see:-)
         
        regards

        Yes, the BBC Nanci Griffith version of the song is a favourite I viewed again recently and somehow paraphrasing the title seemed apt.   But we have to bear in mind that the suspicion is pure conjecture without access to fact and those whose receivers were resurrected no doubt thought 50 euros very reasonable for the result.

        That my EEPROM content was so close to "crashed" yet remained working begs the question of what locations and values would would have totally disabled the receiver?  And could that happening inhibit restoring content from a backup?  My feeling is that the EEPROM could be scrambled yet the receiver remain viable to some degree. 

        But I daren't test that idea!

        I'm pretty sure there wouldn't have been any expensive test gear or a copy of EX2099 within a million miles, what they actually offered was....
         
        "We include original & repaired eeprom on floppy/cdrom, and tuner alignment of the receiver is included in the service"
         
        Which to me sounds very much like....
         
        "We'll use Patrick's software to read your EEPROM data, replace it with his set of average data, and send you a copy of both, plus we'll also use his FFT option to adjust your reference crystal frequency, and that'll be 50 euro and thank you kindly sir" :-)
         
        I could never understand why the price took such a leap, if the set had already been discontinued and that was the resulting speculative price from Ebay sellers etc it might have made a bit more sense, something like the silly prices again that the unlocked sets were fetching, but to double the retail price overnight was certainly an "interesting" marketing technique.

        Yes suspicious considering the required test equipment, experience and time involved.  Applying Icom's (leaked?) alignment program and procedure would be an unusual bargain if 50 Euros (even in 2005).  I remember PCR1000s took a huge leap in price (doubled?) toward the end of manufacture and it's now become a classic used bargain.  The instant I acquire another, first task....backup!!

        Hi Patrick
         
        I'd say it was pretty damn good:-)
         
        Having the average data set was, and is, one heck of a bonus for anyone with a corrupt EEPROM who hasn't backed it up beforehand, but given that the original data from any PCR1000 is the specific alignment data for that particular radio taking a backup to start with is always going to be the best option.
         
        With my first receiver I was very careful to back up the EEPROM once the option became available but must admit to becoming complacent with this one, I've had it for nearly a year and didn't even think about backing it up before the recent question about the manual, but Fred's experience has certainly shown the need is as strong as ever, especially if trying out different software options.
         
        In my recent searches I came across a 2005 post to the group from Spain offering corrupt EEPROM repair plus "tuner alignment" for 50 Euro plus postage. They claimed over 30 sets had already been repaired. It sounds like somebody might have been putting your software to very profitable use:-)

        Hi Nigel,

        Too right about backing up.
        As a long term believer I back up anything needing backing up.
        Then I backup up the backed-up backup! :-)

        The EEPROM content was saved as soon as I became aware of BACKPCR around June 1996 and several further backups since may indicate when the data became corrupted.  I go through phases of interest in listening and it may well have resulted from experimenting recently with PCR1000 programs that mainly didn't run well on Puppy Linux and Wine on a flash drive.

        Following your link and interpretation credibly explains why my PCR1000 showed no dramatic change in performance.   Bandscope and S meter sensitivity were reduced but not greatly, I didn't observe odd AFC problems and operation was not obviously impaired.  I suspect that if my "crashed" EPROM content were loaded to another PCR1000 the result could be similar.

        What I now observe is that Bandscope amplitude is increased by perhaps a third, indicated signal strength is a couple of S points higher on favourite local broadcast stations and displayed frequency accuracy is within a few hertz of zerobeat on USB/LSB.

        So far, so good :-)

        Fred.

        Hi Fred
         
        That certainly looks a lot closer to Patrick's average data, just as well you took the earlier backup, I wonder what caused it to change so much.
         
        It's certainly a warning to all of us that backing up the EEPROM still isn't something to be ignored and I'm feeling much more at ease knowing I've done mine.
         
        I was doing a bit more searching todfay and came across this page........
         
         
        There's some reports on there that show EEPROM results from 14 different PCR1000s and also a calculated average for each location, which are encouragingly similar to Patrick's average values:-)
         
        There's also the indication I was looking for of what each location represents and whilst some are just shown as "reserved", most seem to be reference levels for the S meter and band pass filter tuning points which might explain why a receiver showing very close to the crash pattern, as yours was, could still appear fully functional if nothing more critical had been affected.

        My receiver serial number is in the 02300 range so would be concurrent with when you wrote your program.  It's encouraging that it has proved reliable over 10 years or more.  If being developed and you had been looking for feedback I would have suggested that content and frequency adjustment should not begin without warnings.

        Can you clarify your meaning of "crashed", what the "smart set" is, the simplest way possible to "adjust the frequency" and is the above what the pattern typically becomes?

        Meantime, I'll search for an EEPROM backup done with another program and see if/how it differs.  Hopefulluy any corruption occurred after I made that backup.
        It is interesting that in gereral usage nothing indicated any strangenesses until today!

        Fred.

        I remember there was a pattern for the crashed PCR1000,
        I wonder how your receiver works well if it has the values so identical to the crashed pattern? it's very weird...

        Of course all my statistical model was based on the early production units, I really do not know if things changed on the memory mappings; but it is still weird how close to the crashed pattern your values are...

        you could very well apply the "smart set" of course you need to adjust the frequency as that parameter had very high deviation. Then if you do not like it you can restore your values from your back-up. I did it million times on my unit and I never crashed it once.

        I have a pretty good record of more than 10 years with no-one telling me that crashed his box because of my soft ;-)))

        Completing a bit the story, yes the initial mod was a comparing the different PCBs. The only difference were some surface mounted "resistors" operating as switches giving a hardware configuration. Next some Icom internal software leaked and the rest was easy... ;-)

        Thanks Patrick,
        I sometimes more enjoy getting things to work too :-)
        Never had cause to fix my PCR1000 but followed temptation, installed and ran your program, backed up and compared the EEPROM successfully.

        However, I was surprised that the EEPROM Analysis showed Crashed Pattern Matching = 99%, Values Out of Statistical Margins = 93%, Reference Frecuency Value = 128. 
        Following the "Advice: Your EEPROM shows the Crash Pattern, please apply an Smart Set Average Data" resulted in the EEPROM content being modified without warning and "Ref. Xtal Freq. Adj." required.

        I then decided to exit, play safe and restored the EEPROM content to original.

        The radio appears to operate as before but would you know if anything might have changed that I should consider?
        Also, would the program be valid for later serial number PCR1000s as well as earlier (like mine)?

        Fred.

        It takes talent to write such a program and PCR1000BUR looks intriguing.
        Especially the implication of Nigel's observation about setting the "country code". 
        Does this mean that after backing up a cellular blocked US version PCR1000, if the country code is changed then the EEPROM contents restored, unrestricted frequency coverage becomes possible?

        Hi
        I wrote PCR1000BUR some time ago;
        yes the info on how to use it is within the program.
        I remember the default parameters where taken from the statistic gathered from people's backup files.
        There's only one parameter (frequency offset) that presented a huge dispersion then setting that from a default set of values will sure lead to problems.
        For fixing that parameter the program included a module of FFT that help you to quickly and accurately calibrate the receiver frequency when tuning a standard frequency from a couple of satellites,... I'm pulling this out of my memory, everything is well explained within the software.

        Best,
        Patrick
         
        PC1000BUR was/is a program writtten by Patrick Masotta for backing up and restoring the EEPROM calibration data in the PCR1000 to allow a corrupted EEPROM to be restored without needing to send the radio back to Icom.
         
        It also allowed some EEPROM parameters to be edited and recalibrated.
         
        In order to refresh my memory I've just installed my copy of PCR1000BUR 1v2 and as I suspected there is a help file/manual built into the program.
         
        There were other Backup/Restore programs, one at least of which came with a default EEPROM data file as a sort of "Get out of jail free card" for those who didn't have a backup of their own data, but I don't seem to have copies of any of these anymore.
         
        There's a copy of PCR1000BUR 1v2 in the group files section. It's not the copy I installed so can't vouch for it but I'm sure it will be ok.
        The software won't run if it doesn't find a PCR1000 to connect to, not even to allow the manual to be read.
         
        I do remember now using this software before when I had my first PCR1000 and I've just used it to make an EEPROM backup of my current receiver, which is a very quick and easy process.
        I generally use Icom's own control software, and Icom always insisted, in the past anyway, that an EEPROM could only become corrupted through using third party software, well the would wouldn't they:-), but there's no harm in having some insurance.
         
        As an extra "bonus" I see from the manual that there's also an option to specify the "country code" when reinstalling the data so a possible instant coverage upgrade for some:-)

        I can't remember now if I ever installed either of them, again it would have been ten or twelve years ago if I did, have you tried installing a copy to see if it comes with a built in help file?
         
        Regards
