Salem Area Digital Modes VHF Net

WA7ABU has been operating a Digital Modes net on the 145.290 and 52.99 repeaters for over nine years now (2004).

 The net is usually hosted by Dan, WA7ABU or one of the digital enthusiasts.

Please join us Wednesday nights between 0830 PM and 0930 PM Local time.

Modes used on the net so far have been MT63, PSK31, SSTV and RTTY and some other newer modes, such as WinDRM and DRM (EasyPal) with MMSSTV dominating the net.

I'm also glad to help with software or hardware issues for net members. Email me at [wa7abu(at)arrl.net]

Freeware:

EasyPal VK3EVL is making this program available on the listed site.  You can find his software for free at this location: http://www.vk3evl.com/
This is a developing program for a DRM version of SSTV and can be used for text and sending forms, such as the ARES IC-213.  This is a program being tested on our nets with the WA7ABU digital group.

This is a typical shot of the screen on EasyPal.

MM software is from a well known Japinese author, JE3HHT, Makoto (Mako) Mori.  You can find his software for free at this location: http://hamsoft.ca/
He includes programs for RTTY, (MMTTY), PSK, and SSTV, (MMSSTV).  His Slow Scan program is tops in our view, used almost entirely by the WA7ABU digital group. Select the MMSTV sidebar. I suggest careful reading to avoid other downloads of no use to us.

Here is a little program that will allow you to save your Sound Card Settings. QuickMix
You might want to verify the settings (both on HF and VHF) and then save a profile using the name of the soundcard program. Then all you have to do is place then profiles in a folder on your desktop and double click on the proper one before you open the said program.
