Re: How do I best operate a 4S-Tuner with a Doublet antenna ?

I've got an Emtech ZM-2 I built about a decade ago. Still works like a champ. It'll frequently tune what my Elecraft T1 won't. I needed to use it for my Cricket 30 because the antenna was really lousy, and the Cricket wasn't putting out enough power for the T1. I might get one of those QRPGuys multi-tuners, though, that looks sharp. I've got a lot of their other gear.

Speaking of magic/fun, and antenna experimentation, and balanced wire feedline... you might consider adding a z-match tuner to your arsenal of ham goodies. Something like:


Both tuners are great designs, but are targeted at different types of antennas. A tuner like this one may be a better choice for your balanced feedline.

Try both -- experiment! WSPR and/or the RBN can help you evaluate how things are working. Have fun!

I have been using WSPR for a couple of years now to check the effectiveness of my antennas for TX & RX.  In just a few minutes you can see just how your system is working, make some changes and re-test.

Hi Bob,
Antennas are the magic part of ham radio.
Your 4sqrp tuner is a great one, basically designed for use with a "random length wire" antenna and a counterpoise wire.
