Hello, I am looking for a UHF CB bin file for a 92 Remote, it`s a U band all I need is 1-40 simplex 41-48 duplex, thats all no selcall, no ctcss just basic CB...
Hi everyone, As a newbie to these radios, can anyone help with any info on how the EPROM coding works for the 250 channel E band FM914PM. I have made an...
Take a look at Skinny's page at: http://skinny.8k.com/fm92.html Don't know if it's for a U-band, but that may not matter. ... From: FM900@yahoogroups.com...
Hi Alf, Looking at the PYE museum the FM914PM seem to be military variant of the FM91 or FM92. I vaguely recall some mention that the channel data is not...
Hi all, I hve just came accross an interesting problem, I have a remote head unit that switches itself instantly after you turn it on (maybe 0.5 seconds after...
Hello, thanks I have seen that but it is not a basic file, it has voting etc I just need a CB only file, cheers ... Behalf Of Ian ... band ... ctcss ... find ...
I expect you mean it switches off after the .5 sec. The issue is in the head. It usually is found in units that have not been used for a very very long time. ...
ok mate. ive got the software working sort off. it loads up i choose the new job file type in the file name enter in the hardware and software codes then press...
Yup, as mentioned below, you have to edit the fm900.cfg and make sure that all your file locations are correct, otherwise you will keep getting the same error...
Hi and thanks, but the head is NOT the issue. ATM I have 6 heads and 6 remote bodies here, all heads work, so far I have got 4 radios online. As mentioned...
If the head and cable are known good, and have been used recently, then it's unlikely to be a lack-of-use problem. Sounds like the software may be hanging in...
It could be that you made a mistake entering the hardware code, or that the version of FPP you have doesn't support the type of radio you are programming. Take...
Also check the remote cord for pins not sitting correctly, Sometimes the pins on the cord or the base can push back in causing an o/c After all the usual, as...
Hi Mark, Thanks for your reply. It appears to be a simplex radio and presently there is a 5MHz offset between Tx & Rx channels. Looking at the code, there is a...
Hi all, As I have been looking about, compairing a good radio with the bad radio (comparitive voltages etc) I have detected the 500Hz signal on pin 10 of the...
Hi Jason, Pin 10 of the CPU is involved in controlling various circuits in the radio including the A/D converter that monitors the RF detector. It would appear...
Hi Alf, That makes sense - 250 channels of 8 bytes each would just fit between $1730 and $1F00. How did you create the binary file for the 914? If you used the...
G'day Mark and the group, as posted in the subject heading "Problem Solved", some goose (last person to work on the radio) has swaped the 2 4 pin connectors...
After all that trouble the Radio won't TX. RX & TX VCO voltages are correct, so, time for some more Diagnostics GRRRRRR. But It's not going to beat me. P.S. I...
Hi Mark, The file was created by uploading the EPROM contents. I have an EPROM programmer that can transfer data in and out in various formats. The usual one...
Hi Alf, The FM91 service manual is a good reference for all the FM900 series radios, containing fairly detailed technical description of the design. If the...
Hi all,I am trying to remove an Expansion kit (nsc810an chip) & the CTCSS modual from one radio (UHF) and transplant it into another (VHF), while keeping the...
Hi Jason, One thought, have you changed the hardware/software codes, not just the channel programming, to reflect the changes? 73....Eric VK2VE. _____ From:...
Hi, thanks for the suggestion Eric, I have already changed the hardware and software settings for "NO CTCSS and NO expansion Hardware" Thanks Jason VK3FFFJ ......
Hi All, Thank you for the welcome to the Group. I have worked on many FM92's in the past and done most of the published mods to various sets, refurbished noisy...
Hi, this may or may not help, have you checked any of the electrolytic caps in and around the area of interest, I have found a few caps that are not (no where...
Any luck fixing this one yet Keith? If not, make sure the 'VCO Fine' signal is reaching the VCO on the RF PCB. This is the one that does the higher frequency...
Thanks for the replies Mark and Jason. I have fixed the fault. Your tip, Mark on the fine VCO signal doing the high freq modulation prompted me to measure the...
Hi all, I have stumbled accross a solution that seams to work, in the service manual it says that link 403 must be cut and links 405 and 413 must be installed...
