Hi all, Rcv'd this, this morning. Some interesting points re the discussion coax vs. twin line for amateur HF use. I suppose "open-wire" ladder line is what is being criticized below. Open wire line,
Hi Reid, (Wonder if we are far separated relatives, hi), The B is a completely different unit, even looks different. Has three buttons on the front, a red one for power, and two others labeled Gate a
Aloha, And, thanks to all who have responded to my question. I now understand that the ratio of E to H in space has NOTHING to do with antenna design or use! However, I am glad I asked the question.
Hi all, Well, here I have been having a great time measuring all sorts of things with my new 259B; had it about 3 weeks now. Yesterday, I read a post that one should absolutely insure that your new 2
Mine does not. Hi Dick, Setting the 259B to a precise frequency is just about NOT possible! Even on 40 meters, just a touch of the tuning knob, and the frequency deltas several kHz; and on the higher
I responded in error to Dick in the following: Obviously there has to be a gear drive in this unit; it requires several turns of the tuning knob to cover one of the frequency band selection ranges, b
- Yes, but I bought my new 259B three weeks ago; did the 6F1 come out a week ago? So far NO answers from anyone, including MFJ who I have also queried. 73, Jim, KH7M -- FAQ on WWW: http://www.contest

Hi all, in response to the following: I write: Yes, the antenna's impedance is a "fall out" from the geometry which produces the azimuth pattern. we look at the pattern and make judgments about the a

Aloha, Some of you may recall I had raised questions about these tests right after returning from Dayton, where I heard Steve's talk. My thoughts were posted in late May, and Steve asked that we refr

Jim, KH7M had written: David asks KH7M: Having not heard anything back from Steve Best, I will go ahead and answer David. No, of course not, the feed system has created nothing. What has occured is t
Aloha Ward, Well now that I have the ARRL BOD and their activities sort of out of my mind, I would like to make a proposal to you and the towertalk reflector. There are certainly plenty of us intere
Hmmm? See my name still remains as part of the subject line. Otherwise, I would not comment; however, such time domain problems as discussed above are of absolutely NO importance in HF amateur radio,
OK, so I just loaded 10 new Duracell batteries in my 259B, and out to the base of the TL160 to measure the resistance and reactance. Gladiator TL160 is 38 feet long, with base up about 12 feet, so to
Nope! Always the speed of light in the coax or twin lead reduced by the velocity factor of the particular line, typically, 60 to 80% of llight speed. Of course not, the echos on the transmission lin
Thanks to God that lightning strikes are a very minimal problem in the Hawaiian Islands. We have sufficient others to worry about: volcano eruptions, tsunamis, earthquakes on the Big Islands, and the
Aloha Mike, Six years ago I received both a zoning variance and use permit to have a crank up above the palm tree tops -- the supposed height limit here on the island of Kauai. I was to have the ante
