KA1MUQ's Amazing Homebrew Hybrid Rig
Nate KA1MUQ is still working on this rig and so has not yet produced any detailed schematics, but he sent this to us to show that true homebrewing is NOT dead. Indeed, his magnificent work shows that it is not! This is a 5 band SSB transmitter using both transistors and Thermatrons. I see a crystal filter from Mostly DIY RF in there. FB! And Nate tapped into Pete Juliano's tribal wisdom on homebrewing and hybrid rigs. Pete commented that the three 6146s in the final reminded him of a Yaesu FT-102.

Mike WU2D POTA CCC Camp Activation (21 October 2024) with 1930s-era Station -- See If You Can Contact Mike!
Frank Jones lives! See if you can work Mike on Monday. Let us know if you do!
--------------------------------
Bill,
I’m scheduled to tour the Civilian Conservation Corps. Camp at Bear Brook State Park here in NH on Monday. This is the largest totally intact camp in the country.
I will be activating POTA with the 1930s portable Station. The POTA CCC Camp event is scheduled for Monday around 2:30 ET (if I get everything setup after the camp tour). Primary 7057 kHz Sec 7054 kHz.
The station is an internal battery powered, push-pull Jones Oscillator Transmitter at around 3 Watts out, and a two-tube regenerative receiver that is a period ham artifact. So, four type 30 battery tubes in total.
The antenna is a single wire feed Windom with suspended counterpoise so basically an Off Center Fed Hertz (OCFH).
Between the weather, running the station, logging, and doing camera work, and of course, MURPHY - this should be nuts.
1930s Regen with Transmitter – Fully Self-Contained Portable. Note Charger that is attached to top off the internal battery on transmitter. I did not buy the proscribed 25 9V Batteries and make a TX HV pack up! I used a DC-DC converter and a LiPO drone battery! The Receiver is 100% Dry Cells However.
