History for those inquiring minds - a note from
Charlie Wittman
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.
Thanks to Pius Morozumi the club has a Walston receiver for tracking rockets.
Transmitters are tiny and must match the frequencies that the received uses. If you want to order a transmitter, the AeroPac frequencies are;
| Channel | Frequency |
| 1 | 217.485 |
| 2 | 217.495 |
| 3 | 217.505 |
| 4 | 217.515 |
| 5 | 217.525 |
| 6 | 217.535 |
| 7 | 217.545 |
| 8 | 217.555 |
| 9 | 217.565 |
| 10 | 217.575 |
