Hi Rob You should be able to get your T band FM900 on 70cm's just by programming it for T band and then tuning.. I've programmed / tuned W1, U & T band units...
Hey John Yeah I am still kickin, been busy working, you know that thing you retired folk do way too much of. Actually I had a bit of a mid life Crisis, I went...
Sorry for the late reply Chris, Thanks for the good information, After downloading the service manual I can now see the + and - RX L.O. offsets as per the...
hi, where did you download the service manual for the FM92 ... _________________________________________________________________ Are you paid what you're...
Hi James, http://groups.yahoo.com/group/FM900/files/FM900%20Service%20Manual/ Even though the manual is for an FM91 the information appears to cover FM92's as...
Hello again Group, Just a quick Question, when using FPP and adding channels, in the CTCSS box do I put a Y for yes / N for no or an E for 123 Hz, W for 91.5...
When you want ctcss you put whatever letter corresponds to the tone that you want. You are not trying to add freqs that are on the edge of the band are you ?,...
Hi Steve, I thought it might have been the letter codes but wasn't sure... Thanks for confirming that for me 8-) I have programmed another eprom with the...
Hi OK understood. Iam in the UK and we don't have T band we have U band 440-470. I take it the radios were origionaly on 410Mhz if so can you put it back to...
Cheers Steve 8-) The radios are fm92's remote head. h/w 9502 925 40250 s/w 130100011000000 I've done some more checking and they don't have a talk through...
Hi well I had problems programming an eprom for an FM93 as the fpp kept saying the master file was missing, another user told me to download fppupdate, and...
It's Fathers day today and the kids are coming around so I probably won't get a chance to keep going on the radios today. The version of FPP I've got appears...
It is a programming error, Check closely any extra labling found under the covers. My guess is that they were covered to 12.5. Typical of that sort of ooutcome...
Thanks for the reply Peter, The only info inside the radios are the channel charts I think I will program an eprom for 12.5 KHz as well and see what happens, (...
Hi Peter, Your guess was spot on ! Made one change to the eprom, set it up for 12.5 KHz and Bingo, all 3 radios have come to life. ( haven't got to the 4th one...
Yes, it is possible. It requires modification of a couple of bytes in the EPROM - one byte for the default channel number, and one or two for the new checksum...
Well done! Yes, it's a problem when the external and internal labels haven't been updated as these radios have been upgraded over the years. It's possible...
Thanks Mark From what I have worked out they weren’t duplex radios but “ talk through “ radios… ( the ones I have anyway ) From the list of frequencies...
G'day All Even thought the ambulance service only used 25KHz spacing some radio's were setup as 12.5KHz for a change that didn't happen. I am 99.9% sure that...
Good information Geoff, Thank You 8-) I was assuming ( there's that word ) that they were some sort of " Talk through " setup... I still haven't looked at...
G'day Rob I will see what I can find out tomorrow when I am back at work. As you may now have figured out I work for the place that the radios came from (as a ...
Hello again All, Found the issue with the 2 sets that didn't transmit.. it was due to the head unit... The radios came with 2 types of head, one head has the...
Hi Group, Just won an FM92A at auction and want to receive our local community FM narrow radio on 151.675Mhz. Am currently using a scanner to listen. I have...
Hi Daniel, Getting it on frequency should be a simple matter of reprogramming the EPROM and re-tuning. Some of the narrowcast in Melbourne seem to be more than...
