    Anyone using ARTIC HEAT SINK COMPOUND . . . STOP !!!

    Arctic is crap. Tested once, went to the bin. Fun fact: I was replacing power transistor in machine which was more than 20 years old. White thermal paste used back then was still in a good shape. Mike

    Help with interfacing amplifier with Yaesu FT-950

    Thread should start with amplifier name. So you need additional keying circuit. See attached pdf https://www.ebay.com/itm/205483629891?mkcid=1&mkrid=711-53200-19255-0&siteid=0&campid=5336136228&customid=&toolid=10001&mkevt=1 On my side of the pond I get them from nearby electronics store.

    Help with interfacing amplifier with Yaesu FT-950

    On 10 pin plug it is pin 2 and 3 as well. No difference. 99.9% amplifiers go to TX that way. 0.1% need additional keying interface. Like SB-200 or TL-922 Sorry if I expressed myself not clear enough.

    Distorted Receive on NorthStar 990v

    I had plenty of radios older thatn 40 years, and never had to replace all capacitors. Sometimes a few faulty ones, but after diagnosis, not a coin toss. Anyway... @OP check AGC. Mike

    Distorted Receive on NorthStar 990v

    What is next step if after recap is no difference? Isn't it better to diagnose before blindly replace radio components? Mike
