Hi Marty You can only veiw the program as long as all the files are there EG : BIN , CHL , JOB files are in the directory or you will get an error and the...
Thanks Daniel I thought that might be the case. I have made up my own file and burnt the image to my eprom. I have not achieved great success and have some...

Nothing for sale, and note you are after something already on 6m. However a comment that both the FM828 and FM900 take a fair amount of determination and...
Hi Marty If the radio channels are still being displayed and the radio has a poping sound the VCO in the radio is out of lock as the channel frequency is to ...
Ok I have located test point 201 and the vco can. I have connected my multimeter positive to tp201 and negative to the chasis. The reading i'm getting 15.94v ...

Sounds like a dead VCO. It could be the silver whisker problem (Silver in the components grows very fine conductive crystal slivers that eventually short out...
I just wanted to say that it really does please me to know how helpful this group is. After viewing many many messages from the group, I must say how humbled...
Hi Marty Like Mark said Could a dead VCO or the links in the radio are not set to the right settings as some radios run different IF frequencys. ... ...

The VCO appears to be still working thank goodness. I remembered that when I had my uhfcb eprom in I had some tx and rx. So I decided to change eproms and try...
Hi Marty, Good to hear you found the problem. Thanks for posting your findings on the group. Checking the connectors is something the more experienced techs...
I have a fm92 remote head radio which uses an fm91 head. If I make a new image with the FPP program do I need to do anything different because of the 91head,...
Try Dick smiths for the dummy load they should have one Daniel ... _________________________________________________________________ In the market for a car?...
Hi Marty, You can use a 47 ohm 10W wire wound resistor wired to a bnc plug. Not ideal, and you have to limit the tx time, but it can work for limited tx...
Hi Terry, I haven't tried a WW resistor as a load so I am not really sure what would happen, but I have assumed that at 470 mHz the inductance of a WW resistor...
Hi Barry, Yes, not ideal, like I said, but definitely better than tx into an unterminated ant. socket. I wouldn't try it with most modern amateur equipment,...
Hi Terry, NO not a wire wound resistor. It must be something like a carbon resistor as the wire wound has a lot of inductance and will cause all sorts of...
Ah yes; the light bulb. Just tune the transmitter for maximum glow. I can still feel the pleasure I got seeing the bulb glow when I built a small 27 MHz...
Hello again to all members: I have a Fm900 U band which normaly covers 440-470 Mhz,can you get a few More MHZ out of these Band as i would like to put it on...
Hi Marty You need a volume attenuator board fitted to the radio to run a 91 head as the fm92 fm900 have volume knobs (volume pots) and the 91 have push buttons...
... 91 head as ... have push buttons ... are very hard to ... where it has ... Thanks Daniel The radio is already running a 91 head so I guess it has an ...
Yes, there is a master file for the 91 - two in fact - one is a 's' version. The hardware code should choose the correct one unless someone did some...
Ok I decided to program up fm92 remote for my boat. How do I go about making a scan group of channels. I get as far as having to put something in the scan...
From memory you put the scan group number into the SCAN field of each channel screen. ie 1 for group 1, 2 for group 2, or 12 if you want it to be in both...
Hi Marty Make sure code is set for scanning and then put in where it says scanning put a 1 for scan bank 1 and 2 for bank 2 and you can only have 10 channels...
ok I have found in my shed an fm92 remote A band the cfa boys gave it to me years ago. The patch lead had been cut through so i soldered it back together. Not...
