Hello,
In my setup, I use the KX3 as a receiver (only) and a TS-590s as a 100 watt transmitter. (Until the KXPA100 comes out.) To prevent damage to the KX3 receiver while transmitting 100W from the TS-590, I have connected the 590 to the ACC2 port of the KX3 and set the ACC2 IO to PTT=LO. This has worked well for me so far. When the 590 is keyed up, the KX3 goes into transmit (with the TX light illuminated) and the receiver is shut off. However, recently, (probably with the latest 1.30 firmware release), I see something strange and certainly dangerous to my KX3. When I key up the 590 (a quick dit with 5 watts - the minimum), the KX3 TX light goes on, but I can see what I am transmitting (CW) on my CW Skimmer screen! I can tune the 590 to other frequencies and CW skimmer follows the 590's TX frequency. This tells me that the KX3 is actually receiving what I'm transmitting with the 590 even though the TX light is on and the RX should be disabled. Note that the KX3's S-meter is not deflected (no apparent signal). Can someone (possibly one of the firmware engineers at Elecraft) tell me if a recent behavioral change was made to the ACC2 PTT controls? If the change was intentional, is there an alternate mechanism to satisfy my use case? 73, Mark Glenn K7MJG -- View this message in context: http://elecraft.365791.n2.nabble.com/Possible-firmware-regression-related-to-ACC2-IO-PTT-LO-tp7567198.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
