I enjoy working SSB weak signal on 6 and 2meters and 432. Many of the transceivers and amplifiers I use are of my own design and construction. The 6M weak signal segment is the focal point of my operation with both the house and mobile equipped. If I'm operating mobile or hilltop it's a safe bet that I will have 6M SSB.

When not working weak signal I do QRP SSB operations on HF, 6, 2M using homebrew and some commercial gear. I am always planning new additions to the HB lineup.

Commercial radios include: Ten-Tec 6n2. TenTec Eagle, TenTec Triton 540, TenTec Argonaut 505, FT7817, Tempo One, HW101, and Icom IC245, RS HTX252

The homebrew radio stacks include SSB monoband tranceivers for 40, 20, 10 and several different 6M radios. I'm always looking at new technology for transceiver designs.

The station is solar powered for the solidstate gear the solar array includes multiple panels  for 410W total into a charge controller to charge ten 150AH NiCd Cells (13V battery system). This allows me to operate the station without any grid power.

QRV on:

160M [also 80/75 and 40m]low inverted V

80/75M  inverted L

40M  PAR/LNR EF-QUAD [40/20/15/10m], Inverted L

20M PAR/LNR EF-QUAD currently.


10M EF-QUAD and EF-40/20/10

6M  5 elment beam, for omnidirectional I designed and built a lawnchair squareloop.  The beam is a modded Cushcraft A505S longer boom and reset the elements.

2M 11 elements of my design.

432 Now QRO at 50W using FT817, amp and a 15 element yagi.

Antennas on the tower: 5 element (modded A505s) on 6M, HB 11element on 2M, 15 elements on 432. plus side mounted special use antennas [2M 4 element vertical yagi for repeater use, square loop for 6M horizontal omni]. Time to update that picture.

The current wire farm includes a PAR EF-QUAD and 92ft total inverted-L for 160, 80/75 that also serves on 40.  Also A Ef40/20/10 endfed wire for those bands setup as a low wire oiented for east west use.  Though at any given time a new wire or other antenna may be in development or test.

I'm an electronics engineer experienced with analog, RF, digital design, and mechanical design and specialize is prototype development,

Other hobbies include classic computer use and restoration. I focus on DEC PDP-8, PDP-11(Qbus), VAX (microVAX) and CP/M based 8080/8085/z80 computers. I have many of these systems fully operational. I do not collect PCs or Apple.
