[aprssig] Fwd: APRS Meteor test (TX list)?

[spam8mybrain]

Ok, I'll rig the antenna. 
    
Stephen,  do you want to be METEOR-1? I'll be METEOR-2 here on the East Coast pointing west.If I can't get the 2m linear working, I can still use the IC-7100 at full power. That's still 50 watts. How many fellows APRSers in the area am I going to annoy? :-)Andrew, KA2DDOBerwyn, Pennsylvania (just west of Philadelphia)

Everyone is listening by definition,  Even if only one person transmits. we can still ask everyone to see th next morning if they got it.bobOn Sun, Nov 15, 2020 at 12:27 PM spam8mybrain <spam8mybrain at yahoo.com> wrote:I'm trying to get YAAC reworked for bursting. As to actually running a beam-antenna transmitter, I was going to climb on the roof to rig it today, but if no one is going to listen, not sure if there's a point in doing so.WA8LMF said he had a turn-key UIview setup.Andrew, KA2DDO-------- Original message --------From: Robert Bruninga <bruninga at usna.edu> Date: 11/15/20  12:02  (GMT-05:00) To: TAPR APRS Mailing List <aprssig at lists.tapr.org> Subject: [aprssig] Fwd: APRS Meteor test (TX list)?

No one has said they are ready to TX.Maybe a few of you are working on it, but  Im not hearing anything.  I'm sorry that I am so poor health I cannot organize it better.  Just thought I should summarize the feedback I have gotten.The ADDEE's are high power mostly EME stations.  Did anyone see anyone else that responded as if they were working on something?If we dont have a turnkey TX program, I guess we can stand down.Bob-----------------------------To clarify exactly what a high power TX station needs to send is say 30 copies of the APRS grid format in a single burst  IE send this to the TNC every minute:>GG##gg<CR>>GG##gg<CR>>GG##gg<CR>>GG##gg<CR>...>GG##gg<CR>>GG##gg<CR> The TNC will concatenate probably seven to ten of these at a timel into dense TX packets with only a single TX delay, not 30 delays.  The TNC has UNPROTO set to simply "APRS" no path! And set to CONVErSE..Adjust the number (30?) till the TX burst lasts 15 seconds each minute.The result is 30 complete grids in only 200 milliseconds each.  Hopefully short enough so that occasionally one will get bounced somewhere by the extremely short meteor path bursts at VHF. Point beam to a high ham population density at least 600 miles away. Vertical or Horizontal will work.This  will take special software for the 15  TX stations.  (METEOR-1 through METEOR-15)RX stations need nothing special.  Any APRS software should capture and decode and plot a grid report if received overnight.  All of this on the national channel 144.39 from midniight to 6 AM local timeHere is the report form 1998 event http://aprs.org/APRS-docs/LEONIDS.TXTBob WB4APR
