The Keystone ARC in York, PA, runs a SSTV repeater on 28.680. It requires a 1477 Hz tone for 1.5 seconds that (should) trigger the repeater to send a CW-ID.? Then, one can send a SSTV image to be received by the repeater.?
?
I use QSSTV in Ubuntu which does have a 'Transmit Tone' feature (little music note in the transmit panel).? However, the transmit time variable appears to be type integer, so it's 1 second or 2 seconds....not 1.5 seconds.
?
So, I thought I'd try to get FLDIGI (4.2.06) to generate that tone (and give me an opportunity to explore some of the seldom-used macro commands).? Here's what I came up with:
?
<PUSH>
<TXRSID:on|off|t>
<GOFREQ:1477>
<TUNE:1.5>
<RX>
<TXRSID:on|off|t>
<POP>
?
In theory, FLDIGI should transmit just a 1477 Hz tone for 1.5 seconds, then return to whatever cursor audio frequency and TXRSID state it was in prior to executing the macro.
?
It sort-of works.? Audio frequency doesn't change but the rig goes to transmit for about the right time.? Starting with TXRSID selected, it doesn't seem to toggle and it transmits a TXRSID before returning to receive. So,? ?TXRSID:on|off|t? ?and? ?GOFREQ? ?don't seem to work as I'd have expected.
?
I suspect I'm not using these macro commands correctly....I'd welcome anyone more familiar with these that cares to comment/suggest.
