Just another quick blog post, this time some quick notes on running wsjtx to decode digital messages without a radio - over the internet. I still don't have an HF rig, but that doesn't mean I can't listen to HF!

How not to annoy people on the net: Sometimes when I'm using my Yaesu FT-60 I'll hear a weird beep when I transmit which is also sent to the repeater (DTMF). This is because I've accidentally pressed the WiresX button (on the zero key). Easily checked by looking for the symbol in the display, just pressing the button again will turn it off.
There's been a recent interest in
#winlink at the club (used to send email over the air) but being a
#linux user I felt excluded, but another member mentioned pat (a winlink client for linux written in go) and that changed my mind. I haven't used it over the air as yet, but getting it running over the internet was painless. (new blog post):

Getting fldigi connected to my baofeng under Ubuntu was as easy as plugging in my new SignaLink (with the correct jumper settings), firing up pulseaudio and selecting the new sound card for playback and record.

Test of running solar this weekend. Definitely not ultra-portable, but good for operating near a vehicle. Tripod stand gets the base of the Comet GP-3 to 4 meters, 35Ah AGM battery, Renogy 150W panel and controller, Kenwood TM-V71A (2m/70cm).
You'll know you've been practicing CW enough when you start hearing Chickadees calling "2 2 2"
Found a CW beacon on 2 meters near me. FLdigi mostly decoded it, but got some of it wrong - perhaps because it was keyed by hand? In any case it was fun to discover it!
