80-Meter Amateur Radio Direction Finding Activity in Westford

PART of Westford logoAndy Stewart, KB1OIQ writes on the PART of Westford list:

I have built an 80m fox transmitter and plan to deploy it once spring arrives.  I also have two ARDF receivers for 80m. Very preliminary testing shows that the fox can be heard on 3.5805 MHz at least 3/4 mile away on slightly hilly terrain. This fox transmitter consists of an Arduino, which I programmed for this project, and a Cricket 80a (an 80m QRP CW transceiver).  It runs off of a 9.6V NiMH rechargeable battery.

More detailed information and the Arduino source code, can be found at https://sourceforge.net/projects/kb1oiq-ham-radio-projects/files/80m_ardf

You have time to get your 80m fox receivers before spring arrives. Consider the R3500D from China, or the RigExpert FoxRex 3500, or build your own!
