Hi Glen,

You might want to look at this previous eham thread:;wap2

Not sure the cable will do much for you...

Also I might add that you do not use house wiring amperage ratings for single wire runs as they can handle a lot more current. 20 amps on 16 ga in a single run is not a big deal. Many would be afraid to use their car if they know how small the wiring sizes are in it vs house wiring standards.

Modern auto wire uses a different insulation and is rated to 125 C and better stuff is on the way.

Your friend might like to have the Book, "What's Going On Sparks," and the two CD's of ship CW mesages (including spark!) that is published by DH4PB (Sylvester Foecking) note: his name uses an umlautted o in German. The website is WWW.SEEFUNKER.DE  A real blast for anyone interested in marine radio.

Are you certain that it's not an internal fuse link?
What did you "fiddle with?
You may want to un-do what you did before putting new parts in.


I have not touched any of the internals yet.
Nothing inside of the radio has been changed or moved.

I did not follow the procedure to properly tune the thing.

The receiver is still working. the radio turns on alright. I can hear stations. I just cant transmit.

Anyways It will probably have to wait. Might be a nice project to fix when i get more free time. Meanwhile i will be reading about bias adjustment.

Yeah this ^ and please do not use capacitors lol ... haha

Blind leading blind. I guess car audio guys have it all wrong when they use them huh...

PVC makes it easier, but the other approach should still work - as well as such things can.  Unfortunately, most
such air-core chokes have a very limited useful range.

An excellent reference is G3TXQ's common mode choke page, which includes measured data on various choke
designs and shows the range of frequencies over which they will be most effective.  For example, 10 turns
on a 4.25" former is most effective from about 15 to 20 MHz, and of limited usefulness on 10m or 40m.

I received my # 26 rolls of red and green enameled wire today so wound a 6 turn secondary for the antenna and a 2 turn primary
for the coax on the binocular core I had. It is just temporary until I get a box made to accept it. I used two 240 ohm Allen Bradley 2 watt carbon resistors in series  for the terminating resistor. I put the resistors and a 90 volt gas discharge tube across them in a plastic pill box.
Wire is 17 gage electric fence galvanized steel about 300 ft long. I am using the antenna for 40 meters pointed N.
Works pretty good. Thanks to everyone again for your input and/or comments. My next beverage antenna will be for the South

[...] but I find it intriguing to use someone else's antenna on another part of the planet.

Yes, intriguing!  I sent out a CW CQ and heard myself from a Web-based receiver in Europe...   Very interesting to hear what the DX hears!

Hi, I have both the ARRL and the RSGB handbooks and followed the instructions to build a choke by just coax, tape and connectors (10ft 7 turns for HF). I tried to make a nice coil but using just a tape some spirals are over the others. I have to say that both the ARRL and RSGB handbooks show chokes similar to mine. Would instead be important to have all the spirals perfectly in place and some PVC material needed to keep the coax spirals perfectly in line?

So 30' x 30' is your back yard - how large is the total lot area?

One solution might be to mount a mast to the side of the house, or on the roof using tripods designed
for TV antennas, and use that to support the center of the G5RV.  Then you would tie one end off
in the back yard (possibly to a mast attached to a corner of the chain link fence) and the other end
to the front yard (finding some suitable support.)

And if you don't have room for the G5RV, consider a 20m dipole, or even 20m and 40m on the same
feedpoint with coax from there to the rig.

Are you a member of the local ham club?  You may be able to get a few members to come over for an
"antenna party" to help you set up an antenna, solder connections, and test the antenna out.  (Its
an old tradition that doesn't seem to happen as often these days, but a great way to learn!)

Quote from: W1VT

If you become known as an antenna junk collector it is possible for someone to offer you a trap vertical for free.

Or enough scrap aluminum tubing from broken CB antennas that you can build your own vertical.
