How true! Once upon a time I used flat 300 ohm TV line and twisted it every so often. It worked. Then I used wider spaced window line and also twisted it for a feed line. It also worked. Now I use ho
Once upon a time I was challenged that my homemade ladder line was somehow radiating so much that it made a neighbor's garage door, two houses away, go up and down by itself. A local 'telephone man'
This is Phil, N8PS, and a devoted follower of audio. It may be a bit off topic, but I've got an odd problem and thought I'd run it by you. I have an SCS-PTC modem (5 pin DIN) connected to an JRC JST-
My background is pretty deep on the electronics engineering side. In reading over Jim's material, it was not hard for me to digest. However, in my field, communications, I often encounter people who
I certainly agree that Jim did a fantastic job and certainly the benefit of his experience is appreciated by many, myself included. This exchange does remind me of "The little Red Hen." While everyon
How do you read the articles if you're not an ARRL member? Don't intend on joining, certainly not to browse them. My point: Are you allowed to copy or even refer them to non-ARRL members? Just a thou
Rick, I agree. The ARRL may have been more member oriented years ago. Today their lobby efforts have become so political as to sidestep their original mandate of supporting ham radio and ALL hams. To
I use the Nye-Viking MB-V-A which does well on matching most anything. It has a tri-filer balun internally and works 1.5KW 73 de Phil - N8PS -- http://lists.contesting.com/mailman/listinfo/tentec<htt
Question: How does the internal balun in a link coupled tuner compare with the a 'tri-filer' balun such as used in the Nye-Viking MB-V-A? Thanks, 73 de Phil - N8PS --
In the past I've had some serious problems with Pay-PAl and EBAY. In private emails, several sellers have told me that they were "under pressure" from Ebay to ONLY use PAy-PAl. Two specifically had t
THE RF SNIFFER That's why I built a little RF sniffer. Basically I took an cheap FSM (eg. a diode, a cap, a variable resistor, an RF choke, and a 1Ma meter) and used a small loop as an antenna. No pr
Typically switching power supplies are much cheaper to produce and weigh less (due to the lack of that heavy transformer). Unfortunately, the 'switchers' actually produce more noise (including harmon
My first thought, having a similar experience with a sewing machine, is to determine the input source. In my case it was NOT the power line, but rather DPI (Direct Pickup Interference) on an IF frequ
It is most interesting this post has received the multitude of responses that it has without some feedback. Since the washer is a newer type and it has been plugged in (we assume) properly, the idea
Notwithstanding the dangers involved concerning the transfer of voltage from equipment to you, there is also the inverse to consider. That is, the transfer of voltage from you into the equipment. It
Once upon a time I had a problem like that. The thing I noticed was that when I keyed up, it would peg a nearby CB FSM. Taking that as a clue, I made up a sniffer coil and wired it to the antenna inp
the science of a simple device mirrors the more complex. In other words, rocket science is not needed. For years I used a cheap CB matchbox on 10 meters in series with a Bird 43 wattmeter, just for
Yes Jerry, I did reverse the two but the result was the same. Note that I used RG-213 between the two and RG-58 on either side. I tried different lengths of RG-213 from 12in to 45in without much diff
Having this type of problem of my own more than once in the past, I first isolated the problem by disconnecting the antenna. When the carrier did not disappear, I disconnected everything connected to
