Run What Thou Brung- Maximizing Your HTs

As stated in the last post, there's a number of advantages to running lesser expensive gear, namely: It gets your foot in the door for communications They allow …
A great DIY Commo Resource and some considerations
A boat load of DIY Transmitters, Tranceivers, Antennas, and anything else you may need for every band out there I linked the 70cm section specifically for a reason- due to the sheer number of folks purchasing the Baofeng or other Chicom HTs, it might be prudent to help make the most out of what you …

DF Concerns
I'm breaking this question down into two parts so I can give the most comprehensive answer possible. I understand that about any signal can be tracked. But what are the limitations imposed on DF in mountainous territory. Understand the emperitive to avoid developing patterns, but you still have to use comms, or you may as …
