Re: [Elecraft] K3 + SDRPlay's RSP1 as panadaptor

I've used it both ways and found with the IF output signal to the SDR that the sidebands were inverted. Simple solution ... in HDSDR Options -> RF front-end frequency options & Calibration, *check* "Mirror RF Spectrum in general", "Mirror RF Spectrum for Tune >+ 30,000 KHz", "Operate CW in

Re: [Elecraft] K3 + SDRPlay's RSP1 as panadaptor

Yes and it gives you a much wider RF spectrum.  It is protected when you transmit thus no switching or muting is needed.  I've used it both ways  and found with the IF output signal to the SDR that the sidebands were inverted.  Thus a LSB signal appears as above the carrier while a USB signal

Re: [Elecraft] [K3] low audio volume and low s meter readings

Gary -- Did you get your problem resolved? I have a K3 that has low sensitivity on 20 Meters. For comparison, on a given signal, my Icom 756P3 shows S5-7, my KX3 will be showing 5-6 bars on the meter and the K3 will be showing 1 bar or less. With the Preamp ON, I get 2 bars. I did the factory

[Elecraft] K2: KPA100 fan issue + current question

I just finished building and testing the KPA100 that goes with K2 #7225. This kit was a rev C, and I have brought it up to the latest specs. U1 says PA 1.1. #1: It has passed all of the tests, except it apparently has no low fan speed. I have set the temperature of the heat sink using CAL tPA,

The RTL-SDR has a direct sampling mode that will do HF. $30 is about as cheap as it gets. Not as good as a real P3 but it does work. Ken K6MR From: elecraft-boun...@mailman.qth.net on behalf of Bob McGraw K4TAX Sent: Thursday, November 8, 2018 8:14:30

If it will tune to the IF frequency of about 8.2 MHz.  From experience, without an up conversion added, they won't tune that low. 73 Bob, K4TAX On 11/8/2018 9:57 AM, WW3S wrote: Can you use one of the less expensive sdr dongles in a similar way? Sent from my iPad On Nov 8, 2018, at 10:19

I used HDSDR software and a BNC T  and a couple of short coax jumpers from the RX ANT output back into the RX input.   Activate the feature from the front panel of the K3S.    The input impedance of the RSP-1  SDR is well above 50 ohms and thus I didn't observe any loading or loss of the

Re: [Elecraft] KX3 booster

Petr, The KXPA100 was designed specifically for this purpose. It is rugged, high performance, fully integrated with the KX3, and very reliable. With PIN diode T/R switching and a fanless design (very large heat sink), it's like having a 100 watt KX3. Also makes a great mobile amp, with

Re: [Elecraft] K3 + SDRPlay's RSP1 as panadaptor

Isaac, I did exactly that, using the HDSDR software. I used the RX ANT output (must activate it from the front panel of the K3) to feed the antenna of the RSP1. You use a BNC tee to feed the antenna back into the K3. Purists use an RF splitter instead of a tee. I have a YouTube video that

I would recommend that you use Win4K3Suite, really does a nice job of integrating the RSP and K3. No relationship with Win4K3Suite, just a satisfied user. de Dave K5MWR On 11/8/2018 8:22 AM, TL_Netvision wrote: Hello all, I am considering using an RSP1 SDR with my K3. I will probably use

Gordon, many thanks. I know about it but it is 50W only. (at the best) I am looking for something to give full standard 100W out as same as other barefoot transceivers. So idea was to have in portable QTH my KX3 reduced to clean 5W out boosted to 100W out which is corresponding to conservative
