Re: [Elecraft] Using your tower as a vertical - 160 or 80

Alan, Thanks for your reply. Your approach would provide 40m capability to replace the 40m capability that my (Sommer) beam loses through detuning. However, I wonder how hard your tuner must work on 40? Enough to create substantial feedline losses when the tuner is in the shack? Anyway, I have

Re: [Elecraft] Vacuum Relays and 30 WPM QSK

Of course. beginning with the K2, all Elecraft rigs have a delay built in -- that is, TX begins 8 msec or more after the amp control line is keyed. On the K3 and later relays, the delay is adjustable. 8 msec is enough for most amps with GOOD relays (vacuum relays), but not enough for slower

Re: [Elecraft] Using your tower as a vertical - 160 or 80

I use two of the top guy wires as an inverted vee. There are insulators near the top of the guys and about 50 feet or so down. The vee is brought to resonance on 80 meters with a center-tapped loading coil, which also acts as a balun. The best match was with the coax tapped right about at

[Elecraft] Using your tower as a vertical - 160 or 80

Years ago, after putting up a heavy-duty crank-up tower with several antennas on a tall mast at the top, I was interested in loading up the whole metal tree for 160 and/or 80. However, I didn't like the prospect of transmitted power getting back into the shack via the existing feedlines, causing

Re: [Elecraft] 80 Meter Verticals

One characteristic of a "T", assuming the top wires run in opposite directions and are of equal length, is that radiation from the top wires is highly suppressed because they are fed "in phase" by the vertical section. That means that nearly all radiation is from the vertical section, whereas
