Does your K3 have gold pins on the front panel connector?  The old tinned pins were apt to cause a lot of weird/intermittent problems. Glad you were able to fix the D25 issue. Dave Hachadorian, K6LL Yuma, AZ On 11/2/2022 9:54 AM, George Fremin III wrote: The K3 that went deaf and I replaced

Practically any electret mic element today is going to be good or even great.  Having come from the era of "cans", with the wire headband, cloth covered cord, and thin metal diaphram, that you wore forward of your ears to prevent hearing damage, I've come to the conclusion that the only

My birthday was last week and my lady asked me whether there was any ham gear I would like.  Since it would be a little pain using the new CM500 I bought earlier, with my Kenwood radios, I looked at the RadioSport. I'm afraid they are simply too expensive, even if someone else is paying.  Over

The K3 that went deaf and I replaced D25 in - has had another issue that I have not understood - and it is only annoying when it happens. Sometimes I will turn it on and it all seems fine but it hears zero signals - it is not that it is deaf it is more like it is not working. It does have

Hi Hal I like the water cooling! I debated about using water cooling on a W6PQL 2 meter amp I built several years ago, ended up with an oversize heat sink instead. Since the KPA1500 power supply probably can't safely be adjusted to 65 volts to best accommodate the ART2K0, the ART1K6 is likely
