Updating Firmware on uSDX+
I recently acquired a used –and seemingly a little faulty– uSDX+. These are the little SDR transceivers all over eBay based on the tr(uSDX) devleopment and produced by a plethora of vendors of varying quality. I believe mine is what is called the ‘white buttons’ model — in reference to the different variations that turn…

Building the “Handi-Finder”!
A few months back I got a chance to head out on another fox hunt in the same public conservation land. Again, using the Yagi with 4Mhz offset attenuator, I was able to quickly locate the general area of each fox, but up close to such strong signals (5W Baofeng transmitters), I was again completely…

Boxing the Fox: Packing up the Foxhunt Transmitter
While a collection of pieces sitting on the bench is great for playing around, if I plan to deploy my foxhunt transmitter to the real world, I need to package it up for the outdoors. Many of the larger foxhunt transmitters seem to use ammo cases or pelican cases, which should be fairly waterproof. Trying…

Arduino Fox Hunt Controller: Adding Morse Code and Auto Deactivation
Since the Mic and Speaker on the Baofeng share a pin, I found I can use the same pin I use to monitor the DTMF to output CW as well. Quick software update, borrowing heavily from the code I found for the DTMF foxhunt controller, which included functionality to tone out CW messages, I was…

Arduino Foxhunt Controller for Baofeng: Adding DTMF Control
I came across a series of Youtube videos which referred me to a now defunct website where someone had posted Arduino codes for a couple of foxhunt controllers– one of which used DTMF codes to activate/deactivate or play special tone sequences. I thought that sounded nifty to potentially add to my controller, so I eventually…
