Re: [Elecraft] K4: panadapter directional coupler required?
Hi Brian, I understand that the panadapter is built in to the K4. The directional coupler added additional functionality to the P3. It gave real power output and SWR, as well as an output waveform. All functions I use today. I was wondering if that functionality is avail in K4 since there is no input from the feedline if using an amp or external tuner. Thanks. 73, Marty - N1VH On Jun 3, 2019, at 4:14 PM, Brian Broggie wrote: The panadapter is built in to the K4's display. See it on our website!

[Elecraft] K3S - N1MM+ CW Message Transmit Decode Question
Thanks Rich. I appreciate the detailed response. Makes sense to me now. 73, Marty - N1VH On 8/18/2017 1:05 PM, Richard Ferch wrote: > Any idea why the K3S decodes the CW message transmission using the CAT > command, but not the MYCALL command?

First off, when you use the CAT command the radio is not decoding transmitted CW at all, it is simply echoing the ASCII text you sent to it in the command. Second, the only transmitted CW the K3/K3S can decode is keying from the paddle input to the radio's internal CW keyer. Keying input from a straight key, a computer or an external keyer, whether it comes into the radio on the DTR line of the radio control port or via the CW Key jack, does not get decoded. 73, Rich VE3KI __ 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
[Elecraft] K3S - N1MM+ CW Message Transmit Decode Question
I have my K3S set up in N1MM+ as suggested on pages 187 & 188 of the Fred Cady manual (38400,N,8,1,CW,Always Off). The radio is set to RS232 = USB and PTT-KEY = OFF-dtr. CW Transmit Message Decode Behavior: (.mf file) When the function key (eg. f4) is set to '{MYCALL}', the radio transits as expected, but does NOT decode the CW mycall transmission. When the function key is set to ‘{CATA1ASC KY *;}’, the radio transmits and DECODES the CW mycall transmission. I get similar results for all of the function keys. Transmit decodes with CAT command, does not the standard command. Any idea why the K3S decodes the CW message transmission using the CAT command, but not the MYCALL command? I have verified that the radio is transmitting in both cases. I have tried various decode threshold values as well.

[Elecraft] K3S - no output power from 14.180 - 14.220
I just received my K3s back from service (IMD updated TX boards). There is no output power on 20M from 14.180-14.220. All other bands and the rest of the 20M band appears to be ok (regardless of mode selected). Is there a setting that I missed? What would cause this odd behavior. I hope I don’t have to send it back for another 6 weeks to get additional service.

Re: [Elecraft] K-Pod MCU 1.09 'F3 Power Up' Question
Hi Fred, I re-installed the K-Pod and K3S firmware. The K-Pod is now working as it is supposed to. I must have had a ‘glitch’ in the original K-Pod firmware upgrade. The ‘F3’ at power up does the correct ‘divide by 4’. The K-Pod now resets itself when I cycle the power on the radio without the need to disconnect the K-Pod. (My K-Pod is powered through the data port - I did the resistor upgrade to eliminate the need for a power cable). Thanks again for your help.

Marty - N1VH - Hello Marty, I don't remember seeing any response to your question so here is what I have found with my KPod: The K3's tuning rate is determined by VFO CTS, FST and CRS and there are two fine rates (1 Hz and 10 Hz) and a course rate (100 Hz) depending on the FINE/COARSE switch. So when my CTS is 200, the K3 tunes 200 Hz, 2 kHz and 10 kHz per revolution. The normal power-on KPod tunes 100 Hz, 1 kHz, and 5 kHz per revolution. (it divides by 2). Holding F3 when power-on the KPod tunes 50 Hz, 500 Hz and 2.5 kHz per revolution (divide by 4).

Re: [Elecraft] RFI on K3s
I had the same issue. It was caused by my Powerwerx SS-30DV. After trying a number of things to mitigate the noise, I ended up replacing the power supply with a Samlex SEC 1235M. Noise gone.

Re: [Elecraft] SS30DV feedback
I have similar spur issues, approx 30khz apart, with the SS30DV on 40 & 80 meters as well. I do not get any noise from my Samlex 1235M using the same power cabling and same installation location. I will try the suggested toroid solution to see if I can get rid of the spurs. I do prefer the connectors of the SS30DV. Marty, K1MTK On Oct 2, 2015, at 11:50 AM, Rick Stealeywrote: We had spurs all over the 80 meter band here on the K3S station that is being run as a remote, approximately 30 khz apart. The main station 50 ft away (but on different antennas spaced 100 feet) had no noise. At first we suspected the OCF dipole, then the networking boxes, then the laptop. Put a gelcel in place of the PS and voila!So it was the SS30 PS. 5 turns of the K3 power cord around a type 31 2.4 inch diameter toroid took all the noise right out.
