Re: Frequency Dependent Device output to Serial Port

+ AA6YQ comments below
I am trying to set the antenna switch on the amp to overcome the auto-band select limitation.? The problem is that amp has band definitions of 20-15 and 12-10.? If the amp selects the antenna based on its frequency detection, only 1 antenna is assigned to a band.? So, you cannot auto select a 17 or 12 m antenna seperate from 20 or 15.? My case is,
?
Ant 1? ?6 m beam
Ant 2? ?Tribander (10/15/20 m)
Ant 3? ?Multiband Dipole (40/17/12 m)
?
The frequency detect/band definition select works, but here is what happens since they did not provide seperate bands for 12 and 17 m.
If I assign 10 m to Ant 2, frequency detect of 12 m goes to Ant2. ?
If assign 15 and 20 m to Ant2,? frequency detect of 17 m goes to Ant2.
If I assign 40 m to Ant3,? frequency detect of 40 m goes to Ant3.? And only can get 12 and 17 m on Ant3 with manual front panel select or remote command (I have check that out with my terminal program).
+ Since your focus is on antenna selection rather than transceiver frequency tracking, you would need to develop an small application that tracks the transceiver frequency via Commander (using DDE, TCP, or UDP) and issues the appropriate commands to a serial port connected to your amplifier. Commander supports the UDP protocol defined by N1MM, so it's possible that someone has already developed the application you need; if so, Palstar would probably be aware of it.
?
Hope this helps.? Also, thanks for working with you in the past on the JST-245 capability.? I use every day.
+ Glad to hear it! ? ? ?Dave
