Hi fellow enthusiasts, I just bought 4 of these units via an auction. The id plate says, FM92R A Band's & they have the MRS901 interface unit attached. They ...
Hi Rob, A few of these radios seem to be turning up at auction lately (did they come from Victoria?). The Hardware and Software codes may add a bit of light to...
I too have some of these radio's. They were a "special" job for SA Police, and with the one contol head, you had both a VHF & a UHF radio, and could LINK them...
Does any one know how to mod these to 12.5khz the board doesn't have the normal links to just swing around and convert, from what I can tell I have a...
Hi all, I have been a little quiet on the group for a while. My first FM900's buttons wore out, and I couldn't turn it on. So I left it on the shelf and played...
I also got one of these a few weeks ago from the guy in vk5, mine was special setup for st johns ambulance SA on 159Mhz. i managed to get mine to 100 channels...
Hi, I'm not sure about using a FM92 head with a FM91 base. It certainly won't work the other way around without some hacking of the head. One reason is that...
Same when I did it too, the jumper you need to change is the power supply sent to the head - for local it is only 5v, just for logic etc, but for the remote i...
Hi all, Thanks for the info peoples. Looks like mine were owned by the Ambulace Service. I've had an ordinary 2m eprom put in and the radio tuned, as per an...
Could someone please advise me where the adjustment for the output level of DTMF tones sent from a controller mic is please? The radio is a PRM8030 vhf with...
Hi all, can anyone point me to the 6 meter conversion article for the FM92. I only need the PA info as I just want to turn the PA into a linear for my...
If you are looking for the article published in AR magazine back in 1997, there is a scanned copy in this yahoo group's files section as fm926m.zip There are...
Hi Mark Your Comment was noted.. (quote vk3bby) "I certainly won't be converting to receive 6m after having done one".. (unquote vk3bby) I started an E band...
... I converted an FM 828 some 15 years ago. Still have that radio in good working order, except for the audio PA which decided to fry itself one day for no...
Hi Group, I am new to this group My name is Danny I live in Hobart, Sorry if these questions have been asked before I have two FM-900 both on 2 meters one...
Hi Danny, Apparently dead transistors in the front end are fairly common, though I've haven't come across that problem myself. Also the evil tin whisker short...
Hi Gavin and group Thank you for all those who email me the help has been great Ok what I found on the tx problem was I was missing the 9.9volt when I pressed...
Had my FM Antenna SWR'd "supposedly" and ever since my volume wont go up to the normal loudness I turn it up full and still have to put my ear next to the...
Darryn, SWR will ot cause RX problems. My 1st thought was the speaker as these are starting to fail due to age. If you changed the head then that rules out...
On second thoughts, my last answer was probably wrong, it that it doesn't necessarily eliminate the antenna. What I was trying to say is do a couple of tests...
No, it's FM - if it were an antenna or receiver front end problem then you'd either have no reception or noisy reception - it will never be "quiet"! Don't go...
Ohh, something I forgot to mention - it doesn't have CTCSS or SELCALL does it? They make the speaker VERY quiet until you receive the right tones.... ... Mark ...
