That VERY Interesting, Adam. Many thanks for posting this. This is the missing piece of the puzzle as to why our radios are built this way! But it is a really poor recommendation, because it requires
I'm using DXKeeper, and it is also free, very nice, and well supported by its author. The HamRadio Deluxe suite now includes a logger. Since I'm happy with DXKeeper, I haven't tried it, but every oth
When this happened to my Titan (in the last hour of a CW contest) it was the main antenna relay (on a board right next to the output coax connector). DO NOT buy one from TenTec -- bloody expensive, a
When I fired up my Titan, I had a problem with one GFI in my bathroom and another in the kitchen. The one in the bathroom actually failed, so I changed it out and now it's fine. The one in the kitche
Apparently Heil has never heard of the IEC and AES standards for wiring of XL connectors used for audio. These are international standards. The lowest numbered pin is ALWAYS the shield. Next one or t
Actually, it applies to ALL uses of XL connectors for audio, including broadcasting, ham radio, sound reinforcement, studios, etc. And a major reason that the guys have been having so much trouble wi

Thanks. Yes, in fact, when I first received it it didn't work at all (that is, didn't tune). I sent it to LDP, and four months later I got it back with new software (or at least that was the excuse t
There are several versions of this connector, each manufacturer that makes them has several --and they come apart in different ways. Nearly all of them have the connector pins molded into an insert t
Simple fix. Connect the cable shield to the chassis ONLY. Connect mic hot wire to the mic input. Connect the control wire to the control input. If the mic cable has "returns" or "grounds" that are SE
Here's a link to a paper I just finished on Power and Grounding for Audio and Audio/Video systems. While some of the material is specific to the needs of those systems, much of it is generic and appl
I don't think you're missing a thing. To respond to John's question, I'll point out that I did address balanced power in the piece. The ONLY advantage of balanced power is that equal voltages are app
As I recall, the original cable that came with my 444 (purchased used) was not shielded. Unfortunately, I can't confirm that by looking at it right now -- it's 2,000 miles west of me at W6BX. But I t
My vintage 425 just started blowing one of the main 20A fuses for no obvious reason. Yesterday, it had been idling (not in transmit mode) for at least 10 hours and popped the fuse. I didn't realize w
Thanks, Stuart. My best guess is 15-20 years. I acquired it six months ago from the original owner. The original tubes were in it, and still had some life in them. Jim _______________________________

I'm encountering a strange problem with my Titan. If I follow standard practice and achieve a 1:1 match with the exciter, then take the amp out of standby, the amp typically shows mismatch on the ord
Hi Ken, No mods at all. As to the drive level, I'm going by the readout on the K3. 73, Jim K9YC _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.
This was on the Elecraft reflector today. I saw a non-functional mechanical display piece of this amp at the Visalia International DX and Contesting Convention last weekend. A not quite final estimat
This was posted today on the Elecraft list. I saw a non-functioning mechanical demo unit at the International DX Convention in Visalia CA this past weekend. I expect the amp to sell for about $700 an
