AWA Bruce Kelley 1929 QSO Party

Last weekend and this coming weekend was the AWA Bruce Kelley 1929 QSO Party. For this event only transmitters of 1929 (or earlier) design/technology are allowed. I try to participate every year. See .

This year I again started out trying to get my Hull Hartley to sound reasonable on 80 and 40. See Somehow since 2009 something has changed giving my Hartley a raw AC buzz and some signal drift. Swapping out parts/tubes and cleaning all of the contacts did not help. As a final effort I moved the entire station away from the shack outside wall (nearest the antenna). It still drifted and had a  T7 to T8 went back on the shelf and down came my trusty TNT.

This coming weekend I plan to be on 80 with my  210 x 2 TNT running 10 watts in and about 3 watts out. The receiver will be my KX3 with PX3 panadapter. I've given up on using a vintage receiver for the BK. 80 meter noise is pretty loud here. I need all the help I can get to hear anyone. Visible in the photo besides my TNT transmitter and KX3 receiver with PX3 panadapter is the backside of my regulated HV power supply. The wood box visible in the near left encloses my 2.5/7.5 V filament supply. In the milk crate is a QRP watt meter and Triplet milliampere meter. Notice that I have a shaft extension on my TNT transmitter. This rig is sensitive to hand capacity. Moving my hand close to the normal tuning knob changes the transmitter frequency making it difficult to zero beat another station without this extension.
