I wrote an application to simultaneously control/monitor PowerSDR
and the TS480. Since 2.0.19RC 1 came out, it can now switch the 1500
antenna to the XVTR port automatically when the application detects the
TS480 transmitting and back to the PA port when transmission ceases.
Can't you have your application key the TS480 and let the application
sequence PTT? That way the application could switch the antenna on the 1500
and then key the TX480.
This would require having a PTT button in the application which the user
would access with the mouse or keyboard. Also would have to inhibit TS480
transmit ability to ensure the user did not key the radio with the Mic or
key etc. User could not use the TS480 hand Mic until the application
allowed it. Semi-breakin CW operation would not be possible under this
scenario unless the key was interfaced to the PC and this would, IMO, not be
practical.
The .application was designed to allow the user to transmit with the
TS480 at 100 watts and to receive with the Flex 1500. QSY's, can be
performed either via PowerSDR or the TS480 tuning knob. Interconnection
only requires a single serial cable and VSPMgr or similar. All transmit
functions expected to be performed with the TS480. Pretty basic.
It seems there is a need for a box to manage PTT for several devices.
Not really familiar with flexwire, but the manual indicates it has
both a PTT in port and PTT out port. Seems like the PTT in port could be
used to switch the 1500 antenna connection when external PTT is asserted.
Latency could still be an issue though, since I don't know if the Flex 1500
antenna switching capability is handled in hardware or software. In any
case this would eliminate the need for an external box to manage PTT but
would require a hardwired PTT connection between the external radio and the
flexwire port. The user could then use the mic and key or keyer connections
of the TS480 as originally intended. Will have to look into this, thanks
for making me rethink the keying issues.
