The user manual has been rescanned in B/W instead of greyscale and is now a much more sensible 160K instead of 630K. It has been uploaded to the files section....

Hi all, First post here, I recently purchaced a W1 FM92 at a swap meet for $5 not working. When I got it home, I had discovered that water had got into the...
Jamie, Congratulations on an excellent find! sounds like you've struck a bargain. Seems as though its a Local model your speaking of. Your correct in that...
I am looking for an FM92 A band to convert and program for 2m Band? Does anyone have one. I require a remote unit No head needed. I am going to use 3 of these...
Hi, Have a w1 fm92 0n th 477 meg cb band but wish to convert to 70 cm also will need to bring back up to 25 watts from 5 could anyone guide me from whence to...
Do yourself a favour - sell the FM92 to a CB'er for loads of dollars and buy a cheaper and more reliable AWA RT85 already on 70cm! ... W1's were never intended...
Hi All, I have just purchased two FM900's W1 band, one of them seems to have a problem with the power/switching circuit. When I switched on it The green power...
A few things you could try before getting out the soldering iron: 1/. replacing the fuses with new 10 Amp ones. 2/. Open the unit and re-seating the EPROM. 3/....
Hi funny as it seems saying for you to aquire an AWA RT-85 on 70cm I have got one of these already on the Victorian 70cm frequencies which is useless to me as...
G'day Surely the solution is to get the RT85 reprogrammed.? I don't have the gear myself but if you ask, then someone will oblige. de bill ... From:...
Yes it would be easy to re-program but it was bought for the likes of it to be programmed on UHF 476mhz-477mhz but the version I have will not align to this it...
The beast has now been converted and all seems well. However the origional setup was I believe for 30Khz separation. The supplied frequecies were 77.42 and...
Can an FM91 control head be used on an FM92 unit? What changes would need to be made? Regards Eric VK5ZAG [Non-text portions of this message have been removed]...
Yes, there are different versions of the PCB. Some have more links than others, so you may have to resort to cutting tracks and/or changing the reference xtal....
The eprom I have burned is for 25 Khz. Strange that the Manual says 25 and 12.5 have the same Div. Ratio and the same links. Skinny says otherwise? If I can...
Hi Eric, I've never quite figured out how the radio and FPP know the step size. FPP only has hardware codes for 12.5 & 25kHz, but the manual has divider tables...
From memory the divider ratio worked out to be 5khz, this lets you get 25 or 30khz chnl spacing. Or the divider was set to give you 6.25kz, this gives you...
Mark, I was once told by someone that was reprogramming radios for 12.5 khz spacing, that you need to program at least one channel to the half khz level. This...
Re-reading the posts on the divider rarios etc, and the FM91 manual, I believe that yes, the divide ratio is the same for both 25 and 12.5 khz, provided the...
Hi Eric, et al. I took a closer look at the 92 series-1 and series-2 manuals. It appears that VHF series-1 had fewer jumpers than the series-2 (6-digit serial...
Well the E band monster is now working 6m hooray!! Most all of the problem was an eprom image that was not suitable for the hardware. A test eprom burned from...
Update on VCO Some person has previously removed the VCO unit from the main board. The unit is a T band. He must have had microphony problems as someone has...
Hi all, The chip capacitor is added to push the W2 VCO down to 430mhz. A W2 can be tuned down to about 430mhz with chip cap and RF tuning slug changes to brass...
Re FM92 on 70cms, I found the following: For "T" band radios, program the radio as "W1" band - this will swing the oscillator injection to the low side. The...
I became dissenchanted with the information available for the 302- 314 links so I measured right at the IC and went from there. some links were straitforward ...
No need for all that, just the two links involved 313 and 314 Barry ... From: agem9999 [mailto:EricWD@...] Sent: Wednesday, 9 March 2005 9:09 PM To:...
