6 Meter APRS Lives

Update:  Dale N0KQX has joined in from SW Kansas as of June 24th. N0KQX-6 has already been heard several times at K4KPN-4 in KY.  The K7BC-6 Virginia I-gate appears offline since the 21st. A few more I-gates on frequency would be nice. I believe I can enable gating on K4KPN-4’s 6m port (ah the flexibility of BPQ32) without impacting general packet operations on that port. I plan to test that option on my next trip back thru 4-land.

It’s not every day you hear and “digi” off the 50 MHz APRS digipeater at the Pentagon.

Map showing location of the K4AF-6 six meter digipeater at the Pentagon. I believe this is part of the MARS radio station located there. Frequency is 50.620 MHz using 1200 baud AFSK packet.

 

June 19th 2018 a nice strong opening into NE Virginia revealed that the 50.6200 MHz 1200 baud 6 meter APRS and long time 6m packet “calling” frequency still has some action on it.

The monitor for the 6m (50.620 1.2k) and 10m packet/robust packet ports at the K4KPN-4 N. Kentucky node. K4AF-6 is at the Pentagon. K7BC-6 is a few miles to the SW. Both are just over 400 miles away. Opening was very brief. June 20th would produce a stronger opening. Times are UTC.

 

On June 20th things would liven up even more with the Conway AR node “CON50” W5AUU-6 (likely bleed-over from 50.615 MHz) coming in. There was also an extended and strong e-skip opening to Wash DC with APRS packets bouncing around and being digipeated like it was 2m APRS at times. Several K4KPN-4’s beacons were getting digipeated and I-gated into APRS-IS via K7BC-6 in Springfield VA.

The June 20th 6 meter APRS opening into the Wash DC area lasted for over an hour. K4AF-6 was even audible at times on a HT (Yaesu VX-8DR) setting on my desk. Gotta love the Magic Band of 50 MHz!

Distances involved where about 410 miles from Kentucky to DC. So I wouldn’t call it really short skip, but definitely shorter than normal. General rule of thumb is when 6 meter e-skip shortens up to 250-300 miles then it’s time to start checking 144 MHz for possible e-skip on that band.

Good to see there is still some life on 6m APRS. Band openings can make things interesting, even on VHF packet. Also nice to see there is some packet radio gear at the Pentagon MARS / AR station(s).

K4KPN-4’s 10m port beacons every 10 minutes and the 6m port beacons every 5 minutes with APRS compatible beacons to help detect band openings. The 50.620 MHz 1200 baud port on K4KPN-4 also supports WIDE1-1 digipeating in addition to normal packet radio connects.
