Dropping off my ARRL Homebrew Challenge 3 radio at the ARRL Headquarters today


Hitting the road to drop of my entry into the ARRL Homebrew Challenge 3 (challenge to build a complete amateur radio from scratch).  This is for the 10m and 6m class.

TX power is about 70-75 watts on both 10 and 6.  It uses the NXP BLF647 LDMOS for the PA, an Si570 for the VFO, AD8009a current feedback op-amps for the pre-driver and first IF amplifier.  It also uses lots of old school parts for the chassis and front panel controls (each of which has an easy-to-find modern equivalent).

I will post two youtube videos soon.  One on the construction of this radio and the 2nd on how to use this radio with an on-air demo.
