Hi all, I currently have in my possession an FM91R T Band. I don't have the remote head for it. I wish to re employ it as an Echolink transceiver. It is only...

Hi Jamie, Sure your not thinking of the AWA RT-85 "headless" plug? I haven't heard of an remote head FM900 series radios being able to run without a head,...

I don't have the connections with me right now, but if you can't find them, send me an email. I'm not sure if all RJ-12 adaptors used in FM900's are the same -...
Nice one Ron! I'd overlooked that file in the past thinking it was just another packet radio audio interface. It makes the radio a lot more suitable for thinks...
Hi Mark, Thanks for the reply. The FM93 that I have only has the RJ12 on the front. I have an FM92 as well so I know what you mean about the DINs on the back....
Hi Dave, Pots are pretty rare to come by, although there are some blokes that sell FM92/E parts at most of the hamfests around Melbourne. A fortnight ago at...
... Z273 ... Lou, I use the 70-1000X programmer from Skyline in Western Aust. There is no need to remove EPROM from Z-273. The whole board plugs into the...
Lou if you have the time and equipment the best proposition is to remove the eprom and replace it with a low profile ic socket. Burning the 2716 eprom is easy...
Hey guys, I am considering purchasing a T Band FM92. From what I can gather I can re-programme the EPROM to allow me to select W1 frequencies but the VCO will...
... I don't have the details, but it would be quite a number of components in at least the receiver front end, VCO and the transmit PA chain. I suspect...

Hi everyone, I've got a bit of a problem with the two FM900 I have in my possession. One is a FM92 W1 Local head and a FM91 Remote Head. Here is the details...
Hi Jamie Every FM900 I have owned has seemed to have this issue. Mostly I find the VCO is the problem. MY Fix, and attempt at your own risk - (It has worked...
All, Place a guard between the VCO & the other components. I use cardboard to deflect the heat. Rather than heat gun, I use the wifes hair dryer… Solves the...
