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.
Should prove to be a very interesting pr ... Read More About This Project

Now that I think about it....I think I will build this N-S/E-W vertical beam completely. Can use my antenna analyzer to get the coils right...easy enough to do. Use 1" pvc as coil form, Tap it and tune with a cap. This way I can make it handle f ... Read More About This Project

Several years ago I converted a Quintron (Glenayre) QT8505 paging transmitter to ham use.
The 8505 is a 500 watt CCS rated VHF paging transmitter that uses 6 MRF174 FET’s in the final, driven by a single MRF174. The PA originally was desig ... Read More About This Project

For some time now, I had been looking for a way to spruce up the keypad used on my KWM-380. The former owner had mounted the standard Pipo keypad on a cheap Radio Shack gray plastic project box along with about an inch and a half wide ribbon cable. I ... Read More About This Project

Since a radial field is impossible at my site I chose the Gap Titan DX. It covers 10M thru 80M. It went up easily. The only band I had to tune was 15 meter. Rich at GAP confirmed the proper approach for tuning. The antenna is on an 18 ft mast tied to ... Read More About This Project

So I've been reading about this Small Space antenna that is being sold as the TAK-Tenna. Really neat idea - Has a 30" boom and Sprial Coils on the ends. See a picture at http://www.taktenna.com/
Looks easy to built - Right !

I'm building a portable repeater for emergency operations (search & rescue,law enforcement, wildland firefighting).It will work on 2m, 70cm, crossband, GMRS, and the federal VHF band,by changing out portable radios.

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
from WD0GOF
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.
from WD0GOF
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.

I am starting work on a simple system that will allow me to operate the LEO birds with simple light weight antennas. What I am thinking is a set of VHF/UHF egg beater antennas that are controlled by a microcontroller.
Ideally I would like ... Read More About This Project

This project was built to overcome my lack of CW skills and to hasten my ability to get on the air. The only working radio I have is a QRP rig so I want to go CW and RTTW quickly. The interface isolates the Radio completely from the computer using ... Read More About This Project
