Barrett 2090 CAT PTT control

CAT PTT control has been added to the MARS MIL-STD-188-110A Data Modem Terminal (DMT) software for the Barrett 2000 series (2050, 2090, etc.), thank you to Steve N2CKH for implementing it.

Transmit functions with the following changes to the basic config when running it with the US Navigator:
Data Port 0   9600
CAT COM Port 6  9600

In order to use this software, I am actively seeking fellow HAMs who are interested in digital communications with a Baud rate above 300 (60m Band only).

Solar power for portable Amateur Radio

I finally took delivery of my last item of my portable solar solution consisting of:

- a PowerfilmSolar R28 rollable waterproof panel
- a Genasun GV-5 charge controller
- and an A123 Systems 12V drop in lead acid replacement Lithium Ion Nanophosphate battery.

To the best of my knowledge, these products belong to the best in their class. Will write more about why I chose these items in future posts and will inform on how they perform.
