PMRC Digital Education Net
Every Tuesday evening at 1900 (7:00 PM)
Let's meet at 7:00 pm on 147.030 as usual
for a "no-mic" all digital one-hour net using our
most reliable checkin mode THOR 22.
Listen for instructions at the start of the net with THOR 22.
Always keep your RxID turned on to identify the digi mode.
Last weekend saw a great deal of FLMSG "Storm Report" traffic on the HF 80m NBEMS nets. So let's practice tonight sending sample "Storm Reports" from your station. Open the FLMSG and pick Storm Report, then fill it in with sample drill message data. You have to SAVE it before FLDIGI will allow you to send it. We'll use MFSK32 for traffic, all centered at 1500 Hz on the waterfall.
For the 8 pm - 9 pm voice net, I am open for suggestions. Rig Control did not seem to have much interest. We've covered Sound Card Oscilloscopes before, and Satellite Tracking Programs, Winlink, APRS, various Packet modes, Packet Sound Modems, YAAC, and a host of other apps in the past few years.
Perhaps it is appropriate to go back and deal with some fundamentals about modulation and digital "modes". What exactly is "modulation"? How is it accomplished? What is "data rate", "symbol rate", bit depth, error detection and correction? Why is RTTY a digital mode that is disappearing? Why is there a drop in the fantastic mode BPSK31 on HF bands? Why is the new "top mode" FT8 so popular right now?
Bring a list of questions to the discussion.
Most of you know that on an FM repeater system, almost all of the FLDIGI modes seem to work reasonably well. So why do I like THOR more than any of the other options? Why is THOR a good beginner's mode? Why has 8PSK been difficult to use on the PMRC repeater?
We've also used the repeater and the DEN for occasional practice with the very first digital mode CW (or MCW as it appears on a repeater). For those of you who like to operate CW on the HF bands, what do you find works best for you: a straight key, a keyer, a keyboard?
Should we occasionally do a CW practice net, to encourage copying CW "by ear"?
