Phil, I have a "Center Fed Zepp" that presents an inconvenient feedline end impedance to my tuner on 40 meters, so I add an extra quarter wave, about 33 feet, of 450 ohm ladder line to the end of the
Please tell me the first year that the 544 Triton IV was made. Thanks, Jim, W8KGI _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com
Bob and Lee, Mouser Electronics lists a line of C0G (NP0) ceramic, radial leaded capacitors in their current catalog. They range in value from 10 pf to 0.022 microfarad. I can give you the part numbe
Karl, I'm not familiar with the relay used in the 509, but dry reed relays are quite common. My Mouser catalog has five pages of them. If you can give me a physical description and a manufacturer's n
Maybe it's a BC-610. What is the 610? Paul _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
B&W made the antenna tuner for the BC-610. According to Jack Williamson it was the BC-939. But they didn't build any BC-610's. The BC-375, mentioned earlier as the antenna tuner, was a transmitter in
Vince, I currently have a 600 ohm line bent about 90 degrees. It comes from my 268 foot center fed Zepp, crosses my roof, goes over an aluminum rain gutter and then down the side of the house to the
Ed, Look for a Johnson Matchbox if you want something to tune up an antenna fed with open wire line. They were made in 150 watt and 1 KW versions and some had a built-in SWR bridge on the transmitter
Mike, I've been reading the mail on the Ten Tec reflector about your 160 meter antenna problem. I use a similar antenna, 268 foot center fed with 600 ohm open wire, on all bands from 160 through 10 m
Don't give up on that Argonaut 505. I had mine on 40 SSB yesterday afternoon and talked to a bunch of guys all over New Mexico. My QTH is Sandia Park, near Albuquerque. Jim, W8KGI ___________________
On the question of tuning for Dip versus tuning for maximum output, let me offer a few words of, I hope, wisdom. First, the additional amount of power output that might be obtained by operating the r
Let's start with this assertion from a previous post. "No, it doesn't "tune" your 80 double ext.zepp, it creates a match between the transmitter and the FEEDLINE that allows the transmitter to dump p
I've had an antenna similar to Rick's up for several years now, and I've been quite pleased with it. Mine is a 33 foot, center-fed vertical doublet fed with 300 ohm open wire line. The support for my

I have a Triton IV Digital, and the front panel looks just fine. Guess I'm lucky. Jim, W8KGI _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.con
I just had a look at the display on my Triton IV 544, and now that you mention it the green digit does seem a little dimmer than the red ones. It's nothing that I've ever given any thought to up to t
Jon, I'd suggest that you measure the Q6 transistor that you removed to see what its condition is. An ohm meter measurement of the emitter-to-base diode and of the collector-to-base diode, both forwa
Your idea of setting up a clearinghouse for parts rigs is a good one. Many years ago Electric Radio Magazine used to maintain a list of "Boatanchor" parts rigs and their owners. The owners retained t
Y'all, I worked on electrical connectors of all types for Bell Labs and for Sandia National Labs before I retired in 2003. From my professional experience, I want to recommend a Connector "Lubricant"
Y'all, I've taken on the job of talking to the Albuquerque Hamfest this coming August about significant advances in amateur radio technology from the beginning of radio, Marconi 1894, to the present.
