Forgot to add that the K1 is a 4-bander: 40, 30, 20, 17 meters. -- Dale Holloway, K4EQ www.k4eq.net

I just bought an Elecraft KX2 (I'm awed!) and have decided to put my beloved K1 (SN 3161) up for sale. It has the noise blanker, automatic antenna tuner, internal battery adapter, and tilt stand. Also

Look for the DigiKey videos. Shawn does a good job on those. If the date of the video is more than a year old, it may not be accurate. The biggest change from V4 to V5 (5.1 is the latest release) is

It is difficult to speak intelligently on this design without seeing a schematic, but it is not at all unusual to have a low-inductance choke between the drain of the PA MOSFET and the supply, _if_ it

Whose design is this? Is there documentation anywhere that others could see?

Sorry, 2N3904 transistors at Q14 and Q15; hands don't seem to be working at 5 AM this morning.

Hello Ken, That kit is getting long in the tooth!  :-) Can you send along a photo of the PCB as it currently is built, top and bottom sides so I can have a look at what you've done so far? Can

Yes, I agree with everything you said. I also don't understand how 25 ohms could choke out RF from feeding back into the power supply. Lee

Studying a 5 watt 40M Transmitter that uses an IRF510 for PA, what is puzzling is the RF choke is specified as a T68-2 with 10 turns. By my calculations this presents an impedance at 7 MHz of about

Greetings folks. Finally getting around to building Magic Box. Can’t get a side tone at the side tone test step. Replaced R46 from 10meg to 100 ohm. Prior tests ok. Is this a known problem?

Well, it looks like it will be a while before I can check in to the talk group. The only DMR repeater I can reach is on a TV tower, and the TV people are upgrading everything. No internet for maybe
