This is my second home made radio with 2 band operation 80,40m, the tubes are only for rf amplifier using a pair of 6146, the rest are transistor. The filter I am using Collin 455 khz mechanical for side band filter. 
This is my HF antenna 80M ( upper ) and 40M ( lower ). All are shortened dipole type, 13m total length for 80m band and 9m for 40m band.
