A scratchbuilt G6LBQ BiTx ‘Walkie-Talkie’ for 40 and 20m SSB/CW

After completing a 6-band SSB/CW QRP transceiver (Summit Prowler IV) I found myself thinking about a more compact QRP SSB/CW rig for SOTA, with two of the main day-time SOTA HF bands (40/20m). The design driver this time was to try a different ‘form factor’ — I wanted a rig with a narrow and long case, such that it would easily slide inside a backpack, and on a summit sit vertically against a rock or be hand held. All my SOTA rigs so far use both front and back panels for connections and controls, so they need to sit level on a horizontal surface. As most rocks or tree stumps are low, you can’t easily read the display. Some designers get around this by putting the display on the top of the box, a sensible adaptation but one that makes the rig look like a flounder. Because I spend a lot of time building and using these radios at home on the shack bench as well as on a summit, I wanted a design for use in both situations.

Mt Mitchell (VK3/VN-012), Sugarloaf Peak (VN-011) and Mt Bullfight (VN-002)

My two-summit plan for the day was to drive to Buxton, activate Mt Mitchell (VK3/VN-012) first, then take a leisurely climb up Sugarloaf Peak (VK3/VN-011) in the Cathedral Ranges, and if conditions up there were good, loaf around on the summit.  As it worked out, Mt Mitchell was a drive-up summit, and without rushing anything at Sugarloaf Peak I had time left in the afternoon to drive on and tackle a bullfight.  Well more of a bush-fight than a bull-fight… more on that later.
