Mat (and all), I'm going to order the prototype plate (along with some motorcycle radio project pieces I need) in the next few weeks, then when I finish machine work on a couple of the parts I'll

If you can send a pic of the finished job I'm interested. I put a picture of my version of the mod in the files section a while back:

Hello to all on the list.?? The 980 only requires 2 1.5V AA batteries.? But anything that produces 3 V will work OK,? Anything above that is OK.? Been a 980 user since 1983.? I was told by Chip

Hi Fred and Matt, I am the owner of an FT-980 and the author of this modification. The backup battery is now a CR2032 ! I introduce myself, I am a radio amateur since 1990, RF engineer and I build my

All, I'd indicated in a repair/mod thread last week that I was going to design a mounting plate for an auxiliary cooling fan setup. After a lot of studying and contemplation this afternoon I decided

It's a long shot, I know... but does anyone on the list have one or more of these they want to part with? This is the unit which Inrad marketed for the FT-920. I'd like to fit three of my four '980s

(Splitting out from the "File uploaded..." header) "One thing I found in all the FT-980's I found (5) is the S meter is very scotch.? I hate giving a strong signal that only reaches S5 or 6 when I

My 40/75M FT-980 now has the 3-cell backup unit in place. That mod looks interesting, Matt. Next time any of them have to be disassembled to the point of CPU access (which I hope is never!) I'll

I concur: 4.5V looks to be OK ... especially since the Note: the root cause of the relatively short battery life is extra leakage though R09 (>100uA). There is a simple mod in the Files section (

In a recent shipment of parts, I got the memory battery trap door from an FT-980. On it was attached a 3-cell "AA" holder. The OEM unit was a 2-cell (3v). Looking at the CPU Unit's RAM (uPD445LC)

All, The LEDs are 1x5mm rectangular. NTE3160 (red) and NTE3161 (green) are commonly available and I see a few eBay sellers with other branded LEDs in the same form factor. Pretty sure Rohm and Liteon

One thing I found in all the FT-980's I found (5) is the S meter is very scotch.? I hate giving a strong signal that only reaches S5 or 6 when I get a 5/9.? So raise t5he S meter slightly.? I have

Mat, I replaced the light bulbs with white LEDs. I have some spares that i can share. The details are posted in the Files area. I am away from the computer at the moment so cannot give you all details

What type of LED did you use? Has anyone replaced the meter backlighting bulbs? Drake uses a blue (filtered bulb). I was thinking something like a "cool blue", or "light green" LED might make things

One thing I've noticed is that there are two different CPU Units used in these rigs. They aren't readily interchangeable given the location of one of the connectors on the rear of the unit. The wiring

Happiness is 3 working '980s and a 4th well on the way (test-bench mules are never done). Got an FSK Unit in the mail, swapped into the radio w/ no FSK output...and full output. Aligned the

Thanks Mat for the pointers, will check to see what it is like under the panels and will post some photos, no rush on this one, but would like to have her running for just the beauty that she

Hi Wald, I've also considered installing a TXCO. I actually had to change the pulling trim capacitor (larger value) in the existing circuit to extend the adjustment range ... it has drifted beyond

Hi Fred! "Question for Matt/Wald and whomever else has repaired this assembly: When the RF transformer went bad (open), what were the symptoms? I think this may be what's going on here." I was very
