This is really not rocket science--it's a simple matter of knowing what you are doing. Please contact me off line. After doing this for 40+ years I have had more than a modicum of sucess........ Hard
FYI All, The HP4815A Vector Impedance Meter submersed the main tuning capacitor in an oil bath of some kind to get the capacitance up. Apparently dissipation factor was not of concern when the unit w
They clain they are very long lasting too but I have not found that to be the case. Six months to a year is all I get. I don't buy them anymore. But thanks to Joe for explaining how they work. I did
I've used window line for many years and it is a maintenance hassle. The heat and UV here in AZ just eats the stuff up where it has to be replaced every 5 years or so, and I do twist the line. The la
Just an FYI to all on the reflector. I use a corner fed (~25 ft up from the corner) Delta Loop on 160 and am very happy with it. Apex is at 130 ft. I eventually had to make it with #10 copper wire as
Don, Tnx for your reply. I see exactly whar's happening. In fact I do the same thing with my Delta Loop on 160. It's about 110 to 120 ohms at the feedpoint, so I use a ¼ wavelength of 75 ohm Belden d
Everyone please tell me why I have to practically scream into the mic to get through a pileup with a K3? The FT1000D was no problem, maybe 3-5 calls at the most. OK I could call for 10 minutes but th
Just an observation to all: When Tom, N6BT went to Jaimaca and operated 6Y2J (I think was the call) with verticals on the beach I was blown away. I heard them 2 hours before Sunset here on 160....nuf
Tom, I was totallly not expecting any station from that direction, just thought I'd work a few locals with high incident angles before Sunset here. Then I heard the 6Y2 guys and it was amazing. He wa
Yuri, Thanks for your input. Tom asks, where are the other stations? It is a one pony race. Well I am sure if we look at the CQ logs for that year we will see that there were other Carib stations on
Yuri, I don't think K3LR, W3LPL could afford that kind of property to begin with plus they have to work and have families and all of that. It is nice to do that kind of thing on DXPD's but I would no
Juan, Am I wrong to assume that skimmers are not calibrated? They should be calibrated to S-9=50 uV into 50 ohms at least to provide some kind of uniformity band-to-band and skimmer-to-kimmer. I don'
McMaster-Carr Industrial Supply, Santa Fe Springs, CA has pulleys from $2 up to $357. About 20 different flavors. Hardy N7RT I'm supporting high dipoles fed by RG11 up 120 ft with the 5/16-in stuff t
Ed, I have the same problem. A 25KW station at 1560 KHz just destroys the front end of my K3. Elecraft did not do a vey good job on their front end filtering but that's another issue. I finally had t
Bill, The HPF article was in QST, Feb 1978, p. 22. Hardy Do you have a link to that W3NQN article? I'm only familiar with his work with bandpass filters, and I'm looking for a good highpass filter de
Carl, et al, You have valid points. I have resorted, for example to making my own high power handling T/R relays using Kilovac, Jennings, and other brands of vacuum relays I can find, with my mill an
Don and everyone, Don't forget the ON4KST chat room. I have many Europe Q's for new ones when the station in Europe would say when they were going to call CQ and where. I would go and camp on the fre
I got up last night for my nightly bathroom ritual and just for grins listened to 160. They were calling CQ and I worked them on 2 calls. Not many trying to get them. This was 1035Z. N7RT Why not cal
I think BOG's are under rated. I worked FT5ZM and XV7BM last January with bidirectional BOG, 550ft long that was under 3 inches of snow that was in the weeds of southern Utah. It's all about noise...
My 259B seems to have drifted for lack of a better term. A 100 ohm resistor now measures 85 ohms. There are some trim pots inside but no directions on how to adjust them or align the unit. Should I s
