I have thought of that, that would really be the best thing, to have it at the RSO table. I can't say I've seen it before but I've never been to an LDRS before.This is a great idea darrenf! Quick question: has anyone ever put up a frequency board like you'd use at an RC flying club (in the pre-spread spectrum days)? Or as an alternative a dry erase board could be placed at the RSO table to just jot down your frequencies or check which ones are free before you fly.
At any rate, I'll add my info to the spreadsheet (once I confirm what I'm actually on, LOL).
Great idea!
That’s where I got the idea.Thanks for coordinating this. We did this for the last Red Glare at MDRA.
Put my info into your spreadsheet.
Maybe post on the official LDRS 42 thread and link to this thread?So far there are over 60 BFR flights listed for LDRS on URRG's website, but only 5 people have placed an entry on the frequency tracker. If you want your telemetry to work, I highly suggest you put your name and frequency in and look for others who might use the same frequency. There are already enough things to go wrong with rockets, why add to the risk.
Good idea. Thanks.Maybe post on the official LDRS 42 thread and link to this thread?
Perfect! Thank you!Hi Everyone!
Apologies for not responding to this thread earlier, but we will have a frequency tracking board at the RSO desk on the field. The intent is that the flier must register their freq/ID on the board once they have their rocket RSOed. We will ask each person to come back and erase the freq registration within 15 min of coming back from recovering the rocket. We will have a full set of procedures written in the packet you will get at the launch, but the important thing to know here is that the official freq registration will be done per launch on the field.
We have hundreds of registered fliers for this event, so we must have a solution on the field.
We really love the effort here - thanks for helping out!!
I know the new Fluctus flight system is on 915 Mhz.I am going to be building this freq board over the weekend (using a 4 ft x 8 ft whiteboard)
Does anyone have a list of the Featherweight channels/freqs? I could scroll through on my phone app and copy them one at a time, but it would be great if anyone has them in a list (@Adrian A ?)
Mainly, I am concentrating on the Eggtimer and Featherweight freqs/channels with open space on the board for other brands, HAM, etc. Does anyone know if there are any freqs/channels between Eggtimer and Feather weight that conflict?
The Featherweight frequencies are 903.0 through 924.6, in 0.8 MHz steps. There is an A and B channel for each frequency. The new app has a channel list feature which shows all the channels and which Featherweight channels are occupied.I am going to be building this freq board over the weekend (using a 4 ft x 8 ft whiteboard)

FYI, the Eggfinder 900 MHz channels are 909-925 in odd steps (909,911, 913...) and ID's are 0-7. That's a total of 72 combinations. The 70cm frequencies (TRS and Quasar) are 920.050-949.950 in 100 KHz steps. That's 300 possible frequencies... chances are pretty good you can find one that nobody's using.
@Ulyu Any thoughts on this?Thanks all for the feedback!
Attached is my proposed board format - ignore the fact that the headings are all smooshed, they will be fine when I lay out the actual board.
Basic layout is all the Eggtimer and Featherwight freq/channel possibilities are explicitly listed and the last section open for other brands, HAM, etc
On a 4' x 8' board, the cells are 1.5" high and about 6" wide, so they should be more than big enough to get name and cell number in them with a dry erase marker.
Anybody see any issues?
Looks awesome. I tagged the creator of the Fluctus flight computer to see if he could list his frequencies for you.Thanks all for the feedback!

Looks great. Thanks for doing this!After playing around with the layout of the board, I have decided to rotate it into a landscape mode and build a down and dirty easel for it. I think it will be more user friendly and it will handle multiple sections better. If I make each row 1.3" high, it will fit 36 lines across the board. This will give Eggtimer (with 72 possibilities) two sections exactly, Featherweight (with 55 possibilities) about 1.5 sections and leave two full sections (72 lines) for other brands, HAM, etc. If need be, we can use the blank lines left in the Featherweight section, but this board could handle a theoretical 216 fliers at any given time, which should be plenty to get through a day.
While I would love to list all the other brands explicitly, I don't think there will be enough people bringing other brands to justify that. I think leaving 2 full sections open for "other" will cover all the various permutations of trackers.
Walston/Rocket Tracker is in the 1.25 meter/220Mhz band. The frequencies were just below the 222 to 225Mhz Ham radio band and Hams really loathed that people could use that band without a license even though it was out of the given Ham band assignment. The trackers were around 216Mhz or so and the Rocket Tracker and Walston stuff cost a big pile of money back in the day to acquire and use. ($1500.00?) They were "ostensibly" listed as "animal" trackers to get around FCC rules to be used without a license. They went out of business with the modern trackers that were/are more economical to use.Even though it’s older technology, frequency coordination for RDF trackers, such as Walston, might be important also.
