Hi Alan, The sub receiver has a few primary uses:
- Monitoring one frequency (even on a different band) while operating on another. You might be waiting for a sked or a band opening, or waiting for a chance to call one station while tuning around looking for others. Very useful for hunt 'n' pounce operation, field day, etc. - Listening to a DX station with one receiver while listening to a pileup calling him in the other. This allows you to search for a clear spot to call (or find the place where he's listening, by listening to other callers) without missing any of the DX station's transmissions. This works in either SPLIT or non-SPLIT mode. Without the sub receiver, this would typically be done by using SPLIT and the REV switch to periodically search for a transmit frequency. But with the sub, you can park VFO B on the DX station and use VFO A for transmit -- i.e., no need to use SPLIT. - Diversity receive, where main and sub are locked together on the same frequency but they use two different antennas. If the sub's antenna is polarized somewhat differently from the main receiver's antenna, stations subject to fading (QSB) will tend to become louder in one receiver even when fading in the other. This is especially valued by low-band DXers, who have to play every trick in the book to copy weak stations. The sub can have a different band, mode, and filter settings from main. 73, Wayne N6KR On Oct 30, 2013, at 8:23 PM, "Alan Grant" <[email protected]> wrote: > I am a very happy owner of a K3 (whole system) but I did not order the sub > receiver, what am I missing out on > > VK4KO ______________________________________________________________ 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
