Valhalla Ham Radio WB7ELY                  



1000W High Frequency (HF) Short-wave Ham Radio Station.  

 Shown L to R are Timewave DSP (Digital Signal Processor)  MFJ Versatuner, Icom 706 transceiver, and  Collins 30-L 1000 W Amplifier.   Dave operates mostly digital modes RTTY, PSK 31 and CW using a homebuilt interface to a PC and sound card software. Valhalla is a great "Radio Spot" due to its remoteness, open and high location and very quiet noise levels. View 1991 Ham Station




50W UHF repeater slated for the top of Rocky Ridge.  Repeater pair assignment is 441.400 Mhz/103.5 PL tone. This is a GE MASTR II Radio converted from Law Enforcement use. The GE MASTR II is well regarded as a workhorse radio, robustly built. Temporarily located at the new house for testing and range-coverage measurements. Sanctioned by the WWARA

Dave currently runs two antennas, a vertical (Cushcraft R4 Vertical above) and a dipole (to the right) for comparison tests.  Data  shows surprisingly little difference between the vertical and horizontal antennas while running 100 Watts. Contacts in Japan, South America and Europe have been made in recent months.


On the back side of the house is a 140 Ft Dipole fed with ladder line. Note lower right corner, Icom automatic antenna matcher

440.260 Mhz 1W Video Transmitter.
