I just got the remote, I don't have any details about how the actual transmitter and recievers were rigged other than what was written on the inside housing of the remote. > Also CTCSS should not have any effect on any of that, other then they > probably have a CG disable circuit, which in commercial service it is > required to listen carrier squelch briefly before tx'ing.

For some reason, the remote adaptor (radio side) seems unwilling to switch to transmit when the monitor is active, and I've noticed that when I change from F1 to F2, the remote doesn't follow until the transmit button is pushed. I've also noticed that the remote flips the transmit when the handset is removed from the cradle, presumably to make sure the radio is on the selected TX channel. I'm learning about this thing as I go, and I can see the tones on the O-scope, so I know *something* is being generated, but I wasn't able to locate my buttset so I could actually listen. I suspect either my tones are too low or too loud for detection. I'm at a bit of a loss as to how exactly "standard" four-wire, two channel is supposed to work -- I see most tones on pair one, but some tones I see on pair two, which throws me off a bit. Not being able to reliably use monitor or PTT is a bit off-putting as well, but I suppose when I get the tone levels right things should start behaving. -- Kris Kirby <[EMAIL PROTECTED]>
