PMRC Digital Education Net
Every Tuesday evening at 1900 (7:00 PM)
Agenda DEN Jan 15
7 pm - 7: 45 pm FLDIGI (no mic) checkin with traffic FLMSG/FLAMP
Mode will be a PSK mode, and a TxID sent by net control.
Always keep your RxID on during the net. Turn SQUELCH off.
7:45 - I will do a "Guess that mode" Challenge by turning off TxID
Can you now identify a digi mode just by its sound?
The PSK modes are pretty easy to ID by their sounds (warble)
The FSK modes always play one tone at a time, different pitch,
and are nearly Constant amplitude:
MFSK, Olivia, Thor, Domino, RTTY
Olivia always starts with a "Low-tone, High-tone" (Boo/Beep)
MFSK plays the low-tone first, then that sets the "scale".
8:00 pm Those ops that use CAT control in your shack, please present a short description of what you have, why you like it, and how your rig can be completely controlled by your computer.
I can talk about CI-V Icom rig control techniques. The Rigblaster Advantage that I have offers not only an external USB sound card, but offers separate ports for CW keying, FSK RTTY keying, and also a rig control (PTT) thru a virtual com port. I can actually sit at my keyboard and do everything with the radio in another room: change bands, change modes, change filters, etc. In fact, with additional software, I can operate my radio from anywhere in the world with an internet connection. Several PhilMont members do this already (like from the beaches in Florida).
Also.... please report if you operated any of the digi modes during the Jan 5/6 ARRL RTTY Roundup. I managed to get at least one digi mode qso on 80/40/20/10/6 meters, with about half the contacts with FT8.
FT8 was a super mode for short confirmation qso.
I had zero QRM although the bands of FT8 were bursting with signals.
