color=#0000ff size=2>That sounds right. When it's transmitting at 1200
baud, it's receiving at 150 baud with tones around 386 and 486
hz. The back-channel is only useful for a wired connection
really. Just use m0 and m1 to switch to TX mode when you
transmit.</FONT></SPAN></DIV>

reading this right ? Each time you want to TX or RX with the MX614 you have to
change m0 and m1 because there is no such mode as 1200 RX / 1200
TX</FONT></SPAN></DIV>

color=#0000ff size=2>I can help you with the MX614 at least - I've got them
on my website at <A
href="https://www.argentdata.com/catalog/product_info.php?products_id=51">https://www.argentdata.com/catalog/product_info.php?products_id=51</A> ($9)
with cheap shipping to Oz ($2.80). It's one of the few things I've got
in stock at the moment - though I think the crystals already got moved to
the new place. I don't have a quantity discount listed for the 614,
but if you want 5 I more I can give you a break on them. Good luck
finding a domestic distributor - even here in the States you've got to buy
10 at a time through the regular distributors, and that only gets you a
discount to $8.85 each. And they don't like dealing with
hobbyists. That's the only reason I carry them... it bugs me for a
part so useful to hams to be so hard to get.</FONT></SPAN></DIV>
