I am the proud owner of a 1983 Yeasu FT-980. I bought it used in 2010 for $250 (which included a Dentron MT3000A transmatch) and it has been my daily driver ever since (Phone, CW, Digital). I will be using it this weekend in the ARRL RTTY RoundUp in fact. I enjoy the fact that it is built like a tank, have a very high receiver sensitivity, and is very to work on/repair.

I've repaired it several times, and have made a couple of minor modifications:
1. Buffered IF Out for a panadapter
2. Added an always on silent fan to the fan
3. Added the AM and CW-N filters

I would like to assist the Hamlib group to debug their FT-980 CAT Interface from Alpha to Beta or Release. I am also considering replacing the "heated" master xtal with a TXCO (my shack is in my basement, and there are times when it gets a bit drifty due to the ambient temperature changes for some digital modes).

Mat (and all),

I currently own four of the rigs. One is completely accessorized, including the Gen TX board and the keyer module. The others are in various stages of accessorization, down to my bench "mule" which is barebones and is used to develop mods for the others. I'm currently using it to model a frame for a power supply fan assembly which can be fitted to the existing heat sink and will be "always on". My implementation of IF Out will be similar to what Yaesu did with the FT-90x series - and in fact, a YO-901 will play nicely with the FT-980 when cabled properly. Very similar 1st IF DNA, so to speak.

There's a Yaesu-modified FTV-901R w/ cable kicking around the collection, an FC-757AT and two FL-7000 amplifiers - so the peripheral complement is well represented. Amongst rigs of the period, it's my favorite. There are two inline here at the moment.

Your TCXO mod sounds interesting. I've had to replace the 30.0000MHz reference oscillator crystal in two of the radios (Yaesu sold me a handful of spares - thanks Jose!) but a rework of that area may preclude the parts aging out of spec - as they often do. Another thing I'm working on is a bit of reverse-engineering of the accessory band PROM so the rig can be properly fitted with things like 60M and maintain optimum spectral purity. I bought a bunch of red and green 1x5mm LEDs and am going to change some of the yellow indicators out whenever I have the front panels off the rigs.

Lastly, computer control. I'll be happy to assist the group with Hamlib-related efforts. For a bit of retro-computing fun I'm thinking about writing a CAT program for the Tandy Model 100/102 (I have two of the latter). They're neat little computers and would excel in a dedicated role like this. A Model 10x is also small enough that it won't hog your operating desk space.

73 - and Happy 2021 all.

This is great Fred!

I was able to add the always on fan without major mechanical effort (I had to drill a couple holes for the rubber isolation stakes in the heat sink cover sheet metal). If you care take a look in the Files->Mod section for my writeup. Can't hear the always-on fan running, and the primary fan only comes on when I am working a digital contest (like the RTTY Roundup with begins in a few hours).

is there an alternative power supply that can be connected to the ft-980? can a seperate power supply from an ft-107m work with this radio? thanks marc
