Re: Still Kicking after 40 Years ...

I can chime in to this conversation... while Mat was operating ARRL contest I did some work on Dave's faulty FT-980.?? Dave has one that is fully operational and I took his second 980 home for a repair.? I can report quite a bit of progress.? I think Dave's radio qualifies to be buttoned up and returned to him soon.? This radio had several problems like no CW sidetone, no FSK tones (related), bad HAM/GEN relay and non-operational APF/NOTCH controls.? That part donor radio that Dave mentioned came in really handy. As far as the Morse character truncation... I have never positively confirmed that my keyer board fixed the problem. This issue was present when I got the rig from Dave and then disappeared when I replaced the Curtis board with the Pico-keyer (also mounted inside the radio).? Maybe the keying device (FET) works better with the 980 QSK circuit.? But this is just my speculation... Mat, I hope you did not have such issues with QSK.? Or, maybe you have not used it.? Congrats on having this radio put in such a good use! .? I myself usually shy from contests and prefer chasing DX.? My FT-980 has proven itself to be a competitive rig despite the age!? Check out my video clip that I recorded after having worked JT1CO, barefoot: I have two 600 Hz filters in this radio (low and high IF). 73, Wald N4PL

Mat, Great on running the FT-980 in the ARRL CW DX.? I have had a 980 since 1983.? My first is now at N4PL.? Have you run into the first character truncation.? I found this years ago and never got it fixed.? K7JA chip was the VP for Yaesu worked with me on this.? Wald N4PL fixed this by installing a?? keyer in place of the old curtis keyer. I worked and confirmed 167 DXCC on 160 SSB with the original FT-980.? My second FT-980 was one converted to GEN TX by Phil K4DPK.? I ran this on 60 meters.? This one died and N4PL and I use this as a parts radio.? I was gifted 2 more by a silent key family and N4PL who is a great tech has gotten fully working for me.? BTW K7JA said the 980 had a great receiver. 73 Dave K4JRB -----Original Message----- |
