[amsat-bb] Re: COMPASS commands

[Greg D.]

Hi Mike,

Well, this is interesting...  Good news, I guess, but also a puzzle.

I just had a low pass, off to the west, 10 degrees at the maximum.  I tried sending the commands below, as I have tried before.  As before, there were no confirmation beeps.  But, right in the middle of the pass, the beacon came on.  Nice and strong, as if nothing were wrong.  Unfortunately, I wasn't able to record it, so I don't know what it said.  I let the beacon finish, and sent the commands again.  Again, no beeps.

I thought that I have been doing this right, but not getting a confirmation beep tells me that my commands aren't getting through.  I'm sending the commands by hand - DTMF pad on my Yaesu 736r.  I've set up another receiver to verify the tones are being sent, and they sound ok.  Any ideas?  For example, is there a specific rate that the tones need to be sent?
