My next antenna project is to use 2 Parz End-fed dipoles, mounted vertically in 2 trees and co-phaze them to get a little gain. If this works, I will add 2 more so I can switch them from N-S to E-W.

I have two of these inprocess. Power supplies are complete. Every thing works on one now but the RX is just a little (about 6db) weak. I have it narrowed down to RF amp or first mixer. The other has intermittant oscillations in the TX

The power supply has been recapped tested and is completed. The R/T unit is in process. The Rx is finished and working fine. The TX has some bias problems.

Power supply required complete rebuild all caps and rectifiers, now complete. RX works, but motor boats with high level signals. So still have some agc work to do. TX works works great 420 to 550 watts with a clean spectrum.
