[K3, k3S] Panadapter for the Sub Receiver
 
|
One of our field day operators announced that while he was
making QSOs on active bands, he was going to use the sub receiver in his K3 to scan for 10M CW activity. It occurred to me that this kind of scanning would be a lot easier if you could attach a second P3 to the K3 sub receiver. It seems simple. You would need an IF out from the sub receiver, and some new protocols on the aux bus. e.g. QSY on the sub P3 QSYs the sub receiver. etc. Does this idea spark any interest? 73 Bill AE6JV ------------------------------------------------------------------------- Bill Frantz | When it comes to the world | Periwinkle (408)356-8506 | around us, is there any choice | 16345 Englewood Ave www.pwpconsult.com | but to explore? - Lisa Randall | Los Gatos, CA 95032 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Bill,
Getting the IF output from the subRX is not a problem, but adding the 'new protocols' would likely be a problem. So if you just want to monitor the band around wherever the subRX is tuned, that part is easy, just add an IF output to the subRX. I have done that to one customer's K3, it is not difficult. 73, Don W3FPR On 7/1/2016 1:49 AM, Bill Frantz wrote: > One of our field day operators announced that while he was making QSOs > on active bands, he was going to use the sub receiver in his K3 to > scan for 10M CW activity.

Thanks Don.
Part of my reasoning for posting was that this feature might increase sales of P3s. Given the relative lack of interest, I think it remains a user mod. (But my K3 might look nice with 2 P3s on top of it. :-) 73 Bill AE6JV On 7/1/16 at 5:28 AM, [hidden email] (Don Wilhelm) wrote: >Bill, > >Getting the IF output from the subRX is not a problem, but >adding the 'new protocols' would likely be a problem. > >So if you just want to monitor the band around wherever the >subRX is tuned, that part is easy, just add an IF output to the >subRX.

I have a different subreceiver question: The configuration selection is
bnc or ANTtuner ant 2. Does it require a separate antenna? I thought the subreceiver would use a pickoff of the current antenna or a separate antenna.

There are figures on pages 43 thru 45 of the K3S owner's manual (and similar
pictures are in the K3 owner's manual) There are two relays that route signal to the sub RX. One of the options you have is picking the sub receiver's input from the main rx antenna path. That's the one I use. Tap ANT while in BSET to choose main path or AUX RF source.

Leroy,
The subRX will normally use the transmit antenna, be that ANT1 or ANT2 - there is a 3 dB splitter inserted to feed both the main and the subRX. Now --- *if* (and only if) you select the AUX antenna for the subRX, then the antenna connection that you have plugged into the rear of the subRX will be used - whether that be the BNC connector or the non-transmit antenna. So decide on which TMP cable you want to connect to the subRX AUX ANT input. If you want it to be a receiving antenna, then I think it is best to connect the BNC jack. If instead you have two antennas, both of which are transmit capable, then you may want to connect the subRX AUX ANT to the KAT3. When the subRX AUX antenna is selected, receive for the subRX will be from the non-transmit antenna - in other words, if you select ANT1, the subRX will use ANT2 - and vice-versa. 73, Don W3FPR On 7/1/2016 7:44 PM, lmarion wrote: > I have a different subreceiver question: The configuration selection > is bnc or ANTtuner ant 2.

HiOne thing missing is software support. A key api command is missing for the subreceiver and is unlikely to be made available.So, it's an ok mod to get an overview of an area of the airwaves, but not accurate enough for serious use.73 Tom va2fsq.com

I'd definitely buy a second P3 for my sub-RX if the IF Out was on the
back panel and it was incorporated into the firmware... ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 7/1/2016 5:04 PM, Bill Frantz wrote: > Thanks Don. > > Part of my reasoning for posting was that this feature might increase > sales of P3s.
