However, I am not sure how this actually works. Therefore, this question. If the K3 VFO is dialed into 3850 KHz (for example) and the mode is set to SSB and my sidetone monitor of the CW signal is set to 700 Hz (not sure if this matters), what will the other station here if I send something in CW while in SSB mode on my K3. In particular: 1. They are also dialed into the same frequency 3850 KHz, what will they hear: a tone of 700 Hz, a tone of some other audio frequency, or no tone at all. My only assumption is that they are in SSB mode and dialed to the same frequency as I am. 2. They (the other station) are dialed into the same frequency of 3850 but their mode is CW and not SSB while my mode in sending is still SSB. Same questions, what will they hear? Thanks, 73, phil, K7PEH Hello Phil, 1. When in the CW mode, the actual sending frequency is the frequency seen on the transceiver display (assuming zero XIT). As far as I know this applies to all modern transceivers whether set for LSB or USB CW mode. The receive sidetone offset has nothing to do with this. 2. If you wish a station listening on 3850 kHz LSB to hear a CW signal to yield an audio output of 700 Hz, you must transmit a CW signal at a frequency 700 Hz below 3850 kHz, namely 3849.3 kHz. (If the station were listening on 3850 kHz USB, the CW signal signal would need to be at a frequency of 3850.7 kHz.) I think the above information covers all the bases. Your question 2 doesn't mean anything to me because I don't believe any modern transceiver will send CW while set for either SSB mode. An interesting and worthwhile possibility exists by making use of the SPLIT capability. To use the frequency specified above, one would listen on 3850 kHz in LSB mode but transmit in CW mode on 3849.3 kHz in CW mode. With this scheme one can quickly switch back to transmitting in LSB mode by cancelling SPLIT mode. I've done this sort of thing many times. I believe this stunt can be done with any modern transceiver. It can be done with the TenTec Orion but the setup is more complicated and TenTec doesn't tell you in their manual how to do it. 73, Bob, VA3BZ, W8BZ ______________________________________________________________ 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 rehe...@shaw.ca ______________________________________________________________ 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
