[Hallicrafters] HT 44 Question

[Dave, K2DP]

OM's ,

I had the HT-44/SX-117 pair back in the 1960's. The CAL RESET knob on the 
HT-44 is used to zero beat the TX vfo with the rcvr vfo for transcieve 
operation. Don't worry about where the red dot ends up.

73 and enjoy the gear,
Dave, K2DP, St. Louis
