Re: [Elecraft] Power source for KAT500

Sid, The KPA500 requires up to 1 amp when tuning. If you have nothing else connected to the AUX 12V on the K3/K3S, then that can power the KAT500. If the AUX 12V is being used by some other device (P3 for instance), then you can wire the KAT500 to the same power supply that is powering the

Re: [Elecraft] K3S with an external receiver

Jeff, The only way to do that properly is to use a 3dB splitter external to the K3S and the 590SG. Of course, that is only for receive. On transmit, the 3dB splitter would have to be removed and the input to the 2nd receiver protected. The K3S does that internally with the addition of the

Assuming it is in the vicinity of the K3, use the station power supply. If it’s somewhere else, just about any wall wart will work. Spec is 200 mA typ., 1.0A max. Ken K6MR From: Sid Frissell Sent: Wednesday, August 23, 2017 20:46 To:

[Elecraft] K3S with an external receiver

Hi, Is there anybody ever use an external receiver with a K3S as a second receiver… to act as a second receiver that can share the same antenna the K3S use or similar setup??? The reason here is I still a have my Kenwood 590SG that I could enable TX Inhibit for safety, and use it as a second

Just got my new KAT/KPA500 on the August Special. I have both units all wired, tested and ready to go except for the 12 to 15 VDC power connection for the KAT500. What are you experienced KAT/KPA owners using for this power source? What amperage is required? Advice would be appreciated,

Years ago the local law enforcement used 34.980 (simplex) and of course was often plagued by "skip" from other areas. There was no CTCSS then and their solution was to change the 10 code to 9 code. 10-8 became 9-8, etc. 73 K0PP On Aug 23, 2017 19:47, "Phil Kane" wrote: On

Re: [Elecraft] Noise Reduction

Impulse noise gets stretched out in time when passed through a narrow filter, so it must be removed ahead of the narrow filter. This is true whether in hardware or software. Since this is a very common type of man-made noise, effectively removing or reducing it would be very useful. I can't

CHP has totally upgraded their system. They use 39,42,44, and 45MHZ inputs/outputs. Most dispatch comm centers, but not up here in extreme NorCal, repeat the mobiles on the main base dispatch channel. Makes it easier to listen to both sides. They run their extenders in the 700MHZ range using

Re: [Elecraft] Noise Reduction

Maybe the additional noise in the stages between where the filter would be in IF and where it is in AF? I know I'm thinking of multi-stage RF/IF/AF superhets and that might be what is tripping me up when it comes to a single conversion SDR capability. Maybe there is no difference? Or maybe

Re: [Elecraft] Noise Reduction

Doesn't appear to say very much.  Other than the BW difference [RF/IF BW might be more than ultimate AF BW], and provided that the demodulated audio is free of IMD and other obnoxious distortion, I don't see why NR at AF wouldn't be essentially the same as at IF.  Obvious differences in the

Re: [Elecraft] Surprising Behavior on KX3 KXPA100 Combo

If you are saying you switched bands with the amp still transmitting, that would probably cause what you are seeing. There is a short delay after switching bands to switch in the new tuner settings. You should give the amp time to complete the changes before transmitting. -- View this message
