ARRL EFHW Kit build issues MMcFarlen 1 week, 3 days ago
Have you tried using a counterpoise wire? I see there is a connection point for one on the balun enclosure. (Sometimes a counterpoise can provide a needed return path for the antenna current.) Just let it dangle down, or you can run it along the ground away from the main antenna. Try different lengths. If you have just one long piece of wire, folding back the end to make a shorter wire while testing is acceptable.

Question about participating in contests... KG5JAI 1 week, 3 days ago
Hi Bob -- congratulations on the upgrade! It is perfectly OK to hand out points in a contest without submitting a log -- I've done so many times. The stations you contact WILL receive credit for the QSOs.

If it's one of the big, adjudicated contests, I usually try to complete at least two or three QSOs if I'm not planning on submitting a log. When a call sign only appears in one contestant's log, it can sometimes arouse suspicion with the judges.

balum needed on EFHW? KK4LYQ on 21/1/22
From the equipment that is mentioned, I would guess that the OP is not talking about a permanent, home installation. Although dipoles are more efficient, end fed antennas are often more practical for portable ops, especially in areas where there may only be a single suitable support. I also agree with you that if the tuner can produce a 1.7:1 match on its own, I would dispense with the balun.

You didn't mention which exam you are preparing to take, but I will assume that it's the Technician. The Technician license confers very limited privileges on HF frequencies. To communicate worldwide on VHF you would have to use Echolink, which links repeaters around the world via the internet.

If you want to communicate worldwide without depending on the internet, you should set your sights on a General license and a 100 Watt HF transceiver as a starter rig. With an inexpensive dipole or G5RV antenna, you will be able to contact hams in many other countries.

Can anyone tell me how tall the volumes are in the 6-volume set? I need to know if they will fit on my bookshelf.

It's very unfortunate that a slipcase is not provided, even if that meant increasing the price. These large, softcover books tend to flop over on the bookshelf if they are not supported, but I still prefer the multi-volume format over the single mega-volume.
