History for those inquiring minds - a note from This email address is being protected from spambots. You need JavaScript enabled to view it. about monitoring launch frequencies. 

I am the keeper of the list for now as I originally brought the issue to Aeropac due to problems experienced at Dairy Air, TCC this year.

I was testing the recovery gps for the 99k project which will fly at Aeronaut or XPRS and the GPS Flight unit I was using all of a sudden lost tracking and I saw a NEMA devise on my map on the laptop. I reset the system and got mine back in the SWARM protocol and it then changed back to another NEMA location.

I walked over to see who had a unit on and it was James Doughtery and his ARTS2 gps. A GPS Flight unit can track 10 SWARM units per channel but only one NEMA. That is when I realized we has a problem is someone fired up their ARTS unit when I was tracking 99k.

Richard Hagen then suggested and started a list of the frequencies and channels of all tracking as the BigRedBees on the same ham channel with no slotting would have the same problem in ham 70 cm ot 2 meter bands. Richard started circulating the email about the frequency list and then Eric put it on Google docs.

I volunteered to carry on the list for the future. Very important if you want to find your rocket.

Walston Frequencies is now WMI Model Aeronautics

Thanks to Pius Morozumi the club has a WMI / Walston receiver for tracking rockets.
