Ted, ... This illustrates the core of the problem of not having enough total path gain to communicate with the EOC if the repeaters are down. Either the...

Lots of interesting things. I completely accept that VHF SSB (which can also mean digital) communication is really the only practical longer distance VHF mode...
I was checking my LOTW data and discovered I just need Rhode Island for WAS (any mode). I long ago got WAS via paper QSL cards (all on 10M as a Novice) but...
Rick, ... There are probably thousands of IC-706MKIIG's, IC-746's, FT-857's,FT-890's, or Kenwood TS-2000's in circulation that all have 2m SSB capability. Of ...

My first ISP was AOL (July 1995), even before AOL connected to the "World Wide Web". After AOL connected to the "WWW" it was difficult to get on as the...
Moving on to mode/throughput, let me put on my Incident Commander cap... As an incident commander, I would rather have a printed/written message than one ...
Just wondering if anyone in the Northeast would like to meet on 160M while the band is still in good shape and qso in digital voice. I live in Maine and often...
I was trolling 20M today and found a familiar callsign sending CQ. The station was looking to test file sending with NBEMS (VBdigi and FLARQ). It has been...
ST. VINCENT, J8. Dave, G3TBK will be QRV as J88DR for one week. This includes an entry in the ARRL SSB DX contest. Afterwards, he will be active on all bands...
... NBEMS uses the PSK modes for simplicity of tuning, narrowness, and speed. Other, wider modes, like Olivia and MT63, work further down under the noise ...

... NBEMS is the software package, not an actual mode. It includes PSK31, PSK63, PSK 125, PSK250, MFSK16 and RTTY. MT63 and Olivia are not offered. One...
I recall reading years ago horz TV may have been picked over vert because some test showed there to be less multipath and therefore less reflections and ghosts...
I can see that some digital modes would not work very well for ARQ that is decoded in real time. MT-63 and MFSK16 both have latency due to their design. I am...
I recently revisited PSKmail as I had previously downloaded fldigi and was thinking that I had that program working. I did the necessary unzip and untar,...
After reading this thread with great intrust I still fail to see the difference between it and what has been done with the Pactor modes. That is other than...
true John, but function beats pretty most of the time...... "As far as FAE400 goes, I would like to try it. Too bad one can only get it from one source. (gee...
For people who don't want the 'hassle' of installing some perl modules via CPAN there are 2 possibilities: * Run pskmail and fldigi from the pskmail_puppy live...
John, One major advantage of Multipsk is that it works on next-to-nothing for a PC, you can use it on old 486 machines! Every drop-down box and fancy bell and...
All high-latency modes are unsuitable for ARQ. A persistent misconception is that you would be using signals near the noise level. As I have stated many times,...
John, The difference is HUGE! Pactor is a proprietary mode and the primary use is for radio e-mail. The cost is quite high for just that one function and very...
Hello John, ... Pactor 2 and 3 have private detailed specifications which forbid to even decode them (however it would be impossible to work them in ARQ with a...
