[Elecraft] CW power output and remote tuners

[Gary Smith]

Kurt,

I have 5 separate wire antennas: a 160M Inv-L, a 80M inv-L, a 40M 
vert, a 30M vert & a 20M vert. I've got 45 or so long radials 
attached to a radial plate. An Ameritron RCS-8V Remote Coax Switch 
allows me to select which of the 5 antennas to use. I have no 
external tuner to the K3. I use those antennas for these bands. I do 
have an internal tuner in the K3 to make its circuitry happy & not 
fold back power.

16o Inv-L = 160M, 15M, 12M, 10M +6M
80 Inv-L = 80M, 17M + 12M
40M vert = 40M + 15M
30M vert = 30M
20M vert = 20M

SWR readings via a LP-100A Watt Meter
160M = 1.19 SWR
80M = 1.70 
40M = 1.48
30M = 2.05
20M = 1.79
17M = 1.29 (80M inv-L)
15M = 2.39 (160M inv-L) + 1.12 (40M Vert)
12M = 2.38 (160M inv-L) + 1.69 (80M Inv-L)
10M = 1.91 (160M Inv-L)
6M = 1.45 (160M Inv-L)

I have no problem loading my tube amp into this system and on 15M & 
12M I listen on each of the two antenna options for the loudest 
signal that I want to work & use that antenna. Though I do get 6M, 
there's enough coax loss that I don't bother doing much on 6M other 
than give out points for those in 6M contests that can hear me. 
Pretty much though if I can hear it I can work it (unless it's a 
pileup on a new DXpedition, then I have to wait till those with nice 
beams start to taper off) Hihi.

I would like 1.1 across the bands but I don't know that it will make 
any difference on either end. YMMV

Just another option
73,
