Norman, So you say you got a bunch of elements that you believe are not correct. (whether it's 6, 10 or 20 doesn't matter) and you paid some ~$700 for this antenna, correct? Whether I (or anyone) eve
Remind me (please)..as you raise a dipole up off the ground, does the resonant frequency go up or down? I had an all band dipole perfectly set a week ago and now have changed the height on a temporar
Hi Dick, Long time no hear ! It snowed here this weekend, several times. FLA sounds good about now. (Even Milo, Maine is warmer I'll bet) As to your antenna dilemma. I prefer the ZS6BKW, which is qui
WX is finally above freezing ! Messing around with a 2nd or 3rd hand Comtek 20m 4-square here today that I was very lucky and fortunate enough to inherit (tnx agn!) and all 4 (commercially made) phas
I have an old Comtek PVS-160 remote (outside) box but no controller, so I am looking for the desktop controller,. or, to roll my own (easier), the schematic for this 2 vertical phased controller. Tha
Thanks to Lar, K7SV for some great details and Joel K4WM for some future ideas I think I have enough info to roll my own control box for this simple array. CU on Top Band ! Mike VE9AA Mike, Coreen &
OK, so I just put up a 20m 4-square using a COMTEK box. So far, I'm a fairly happy camper. First real gain antenna on 20m in 11 yrs. (gain being a subjective term here) Installed the first skinny ver
OK all, so I ran a quick power dump test with only 100w and my son at the controls in the shack; me at the wattmeter at the array 160-180' away. At 100w, at 14.000MHz, we saw about 500mW (1/2 a watt)
I had been complaining of no gain on my new 20m 4-SQ array but great pattern and quietness and also low dumped power on my new beast. To recap, its a bit of a compromise in that it only has 2 raised
Cal, I work at a hospital. I am also an active ham with an HF+VHF mobile setup I use in the parking lot at the hospital for CWT contests at least once a week. (mostly on 20m) In sunspot peak years I
Jim is of course correct and I made the fatal error of getting interrupted when I wrote that last email and failed to finish my train of thought when I came back to sit down and type. I'm actually em
I've seen the K2TR stubs, K1TTT page and have recently bought the FB book by W2VJN Today, for a change, I had a little spare time so built 2 stubs, but lets just concentrate on one. It was supposed t
Thanks for the many replies so far. So today after I got home from work I tried just running radio A @ about 1w on 7.000MHZ and saw S9 on 20m and s1 on 10m. No change switching stub in or out, so I t
HI Peter, Thanks for your email. Are you SURE ? I am looking right at the K2TR page and also an excerpt I printed from (I think) K9YC or K1TTT and it shows on the 40m station, a 23' stub (1/4wl, shor
OK, hi, just saw your email now. They crossed coming across the Atlantic ;-) Mike, Coreen & Corey Keswick Ridge, NB Sorry it has to be the other way round, open stub at the 20m station, shorted stub
So if that is true Peter, what do I put on the 40m station to prevent 7MHz harmonics from appearing on 20m? Maybe I am thinking about this all the wrong way. I love to learn new things but I cannot b
OMG Bill-really? Well...I am not using the 10m stub. Let's forget that one for just a moment. I have a 1/4WL 7MHz shorted stub (roughly 23' or so and tweaked/measured vy carefully on my AA-230pro) on
Hi Bill & many others, Kimo, Dave, Jim, Peter, Gary, Gerry....I've forgotten a few. You are all very helpful and I am trying to wrap my head around this. I think I have to start from scratch and remo
So, vy late last night, just before bed, I had Radio A straight to the HF9V (multiband) vertical and Radio B straight to the ZS6BKW multiband horizontal dipole. I spliced in the T and the stub on rad
Hi Guys n Gals, I have been getting lots of help, but every other private email (it seems) I am getting is conflicting. Can I go back to basics and just ask this please: Do I put a 1/4wl SHORTED stub
