1)  See all the 60-meter issues in the post I made earlier today in this 
thread.  Especially the considerations of no automatic beaconing.

2)   Conventional APRS digipeater pathing of WIDEn-N is NOT USED ON HF. It just 
lengthens your packets.  Use direct (no digis at all).

3)   I'm eagerly awaiting Andrew's next build of YAAC with manual on-demand 
beaconing.

4)   I'm putting together several web pages on the 60-meter APRS operation, 
including the radio setup, how to configure FLdigi for KISS-mode operation with 
external programs, and how to setup the open-source Com0com tools to mate apps 
that output KISS over serial ports to the KISS-over-IP port in FLdigi.  This 
should be ready in a day or two.

-------------------------------------------------------

In the meantime, my multimode 60-meter igate is now up and listening  24/7 for 
both conventional 300-baud AX.25 packet APRS and the FLdigi-modes APRS  .

It's now monitoring 60 Meters "Channel  5"   ( 5.403.5 MHz USB ) from East 
Lansing, Michigan.  Mapping web page at:

    <http://wa8lmf.ddns.net:14447/>

Main page shows AX.25 RX; click the link in the yellow box for the FLdigi modes RX.

----------- SET UP -----------------

AX.25 300-baud packet mode:    Tone pair is 1600/1800 Hz "KAM tones"


Fldigi modes:

A)  Set FLdigi audio center frequency (i.e. waterfall cursor) to 1700 Hz - be 
aware that FLdigi tries to snap back to 1500 Hz by default each time you change 
modes.  Change the default "Sweet Spot" to 1`700 Hz to avoid this nuisance.

B)  Turn on RSID mode identification to cause my receive system to 
automatically switch to whatever mode you are sending. Click the "TxID button 
at the upper-right corner of the FLdigi main screen.

C)  You can try any modes, but they must be narrow enough to fit through the 
500 Hz CW receive filter on my FT-857.  The radio is monitoring 1500-2000 audio 
I suggest PSK63 or MFSK16.
