Hi, Perhaps it is something to do with the VCO tuning? If the VCO were to go out of lock briefly when switching between transmit and receive then it may be...
G'day all, Can anyone tell where or if I can hook up an analog signal meter to an FM900.Mine no longer resides in its original packaging, but looks a bit more...
Just connect a meter between the 'S' pin (on the RF board) and ground. The voltage is approx 0.5V for no signal to about 2.5v at saturation. Use a high...
Hi all, I'm new to the group so thanks for letting me aboard.. I've got a few FM92 Remotes (E, A & W2) and one FM91 U Bander, only 1 of these is operating at...

Hi, You are not the first to be confused! Philips are good at that :-) I converted a big bunch of ex-CFA FM92's to 2 meters many years ago. I think they were...
Hi Mark and thanks for the reply.. We've made a little progress this end in that I'm now pretty sure this 92 A (1987 mark 2) was re-linked to suit 12.5 kHz...
Hi Chris, I have never figured out how FPP knows what crystal frequency and link settings you have. I have one set up to monitor the 12.5kHz CFA channels...
Hi, From my experience, it is set from the h/ware code matched to the jumper settings. If you have it wrong you can not get the VCO to the right voltage. I...

Hi Peter FPP will only let me enter a hardware code for 25 kHz channel spacing (3 for a local 25 kHz spacing unit & 4 for the remote 25 kHz channel space), I...
... Hi Chris, Well, that's knackered that idea then!! Gonna have to start finding some alternative vehiclkes then :-) 73 James -- Sent using Kmail on Mandriva...
Correction on my last After thinking further about your post Peter, I recalled that I could actually change the Hardware Code to 12.5 k spacing with version...
I have been following the discussion on reference xtal freqs, division ratios, channel spacing etc. over the last few days. I spent some time working all this...
Thanks Ron, for making the effort to put that info all together. I will use it next time I need to fiddle with links etc. Every time I need to work out...
There is a bit more to the answer of this question. Yes, it is correct that you can't convert a local radio into a remote by removing the front and extending...
Hi Guys, The VHF 92 arrived today, and it would appear that the squelch pot is knackered. The shaft is very loose, and will only allow a signal through if it...
There is a range of 9mm square pots that I have used for replacement. They require a small amount of adaption which is quite easy. The value is not critical,...
I'd appreciate knowing how it goes. I tried something similar years ago with an old shakespear 23ch am set. It light up etc but sfa tx and rx after extending...

Greetings Gentlemen. I would appreciate a hand with the UHF Rx circuits if possible please. It would appear the site URL (or I )has a problem with the...
Hi, Yes, broken volume and squelch pots are a fairly common problem. It the knob it hit hard enough it can break the pot beyond repair (some people recommend...
Hi all For those who may be interested (for reference sake), I have now have that Ex CFA "A bander" working on 2 Mts.. The unit had been re-linked for 12.5 kHz...
Chris, Glad to hear it's working! ... Yes, that's the weird bit! It seems that if you have the hardware set up for 12.5kHz, and the software code for 12.5kHz,...
