I bought this rig brand new in 1991 and it is finally starting to show its age. The problem I am encountering is the slow rise to the desired power setting when the key is depressed. That is to say is isn't crisp but instead it has a slight pause and then a rise to the RF setting. It is not...

I have a very nice HQ-129 and have had most of the others along the way. I usually start with the AC power cord and work my way down stream. Replace the power cord with a grounded 3 wire cord. Next, I check the power transformer voltages with the rectifier tube removed. Then it's on to the...

Rider and Gary, Will try these tips this morning and let you know how it goes. Thanks for the input. Should I use DeOxit to clean the contacts? My experience with solid state is very limited. Marc Problem solved: While thinking about the self oscillation on 10 and 12, I recalled that this...

Oscillates on SSB or CW (with or without mic connected), A or B VFO, transmit only. Rx is fine. Don't have a DC power cable, so haven't checked it in battery power . FT990 has a built in AC supply.

Rider, Thanks for the input. Tried all the above and no change. I fear it is a component common to 12 an 10 meters somewhere within the rig. It is strange that it works fine with the dummy load. Just got off the air on 10 meters with another transmitter and the antenna is fine. Keep...

New to this forum, but active on several others places. Here is my dilemma: My FT990 has suddenly encountered a problem on 10 and 12 meters only. It oscillates when connected to my beam or my loop antenna. I have no control over the RF level (goes to max) and of course the ATU has no...
