Hi John, You'll need a KBPF3A (or a modified KBPF3), which has a filter for this RF range. You'll also need a KXV3 (any type), because you have to the low-level transmit signal from the XVTR OUT jack, not from the main antenna jack. (The main antenna path has a pretty steep high-pass response to protect the PIN diodes in the T/R switch.)
Assuming you have the above in place: 1. Tune the VFO to the desired frequency (say 472 kHz) 2. Set CONFIG:KXV3B to TEST (this selects the XVTR IN/OUT jacks) 3. Set power output to 1.0 mW with the POWER control You will of course need an external amplifier of some kind, and depending on how it is configured, you might also need a T/R path splitter to get the RX signal to XVTR IN. 73, Wayne N6KR On Jul 24, 2015, at 3:38 PM, John Klewer <n6axj...@gmail.com> wrote: > I likely just missed it but wondered if anyone knows how to enable transmit > on my new-synthesizer-equipped K3 in the 630 Meter band. > > My transceiver indicates "BND END" when attempting transmit. > > It may be that the firmware has not yet been modified as the band has not > yet been approved by the powers that be.....thanks for info (if available) > > John, N6AX > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to n...@elecraft.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
