Re: [Elecraft] preamp for using an SDR as a pan adapter
I knew I had an issue when I could hear signals on the K3s that weren’t showing on the waterfall. I need to engage Elecraft tech support to see if I need the mod for my K3s, and see what they say about using an external buffer amp or preamp. When I posted, I thought this might be a common problem that others had fixed before.

Re: [Elecraft] preamp for using an SDR as a pan adapter
A friend of mine, Tim AB4B, suggested that I might need a buffer amp to keep the IF being pulled down by the sdr. DXEngineering sells the Clifton Z1. That adds about 6db of gain, but maybe the buffering that it does has an even bigger effect. On Fri, Oct 4, 2019 at 2:18 PM Bob McGraw K4TAX wrote: > In a word, YES.

Re: [Elecraft] preamp for using an SDR as a pan adapter
Some. I was planning on sending an email to Elecraft support with the s/n of my K3s to see if I needed the mod. The difference I’m seeing in signal strength is about 20+ dB. Is it normal for the if-out to be weaker than a direct connection to the antenna? 73, Fred AE4ED On Fri, Oct 4, 2019 at 12:44 PM Don Wilhelm wrote: > Fred, > > Have you looked the K3 IF Output mod? > > https://ftp.elecraft.com/K3/Mod%20Notes%20Alerts/IF_Output_Buffer_Gain_Mod_Rev_A.pdf > > If you don't have the 13k SMD resistor or a 1/8 watt 13k resistor, you > can order the kit from Elecraft. > > 73, > Don W3FPR > > On 10/4/2019 1:24 PM, Fred Massey wrote: > > Good afternoon Wes and all, > > > > If I connect the antenna directly to the QSR-1, I get the same signal > level > > as the K3s.

Re: [Elecraft] preamp for using an SDR as a pan adapter
Good afternoon Wes and all, If I connect the antenna directly to the QSR-1, I get the same signal level as the K3s. But, when I connect to the QSR-1 to the IF-out, the signal is about 4 s-units less.

[Elecraft] preamp for using an SDR as a pan adapter
Good afternoon, I have successfully connected my QSR-1 to my K3s if-out, and immediately noticed the signal strengths showing on the QSR-1 were much weaker. I probably have an early K3s, so the if-out signal strength is even weaker. Any recommendations at a good preamp to use? It seems like 20db is what I need: 73, Fred AE4ED __ 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

Re: [Elecraft] new K3/0 Mini
It would be ideal to also include the band scope of the p3 into the solution. Perhaps the integration of the solution could be encapsulated into a new P3. The functionality of remoterig can be in the new P3, and the P3 scope data could be sent digitally over the internet as well.

Re: [Elecraft] new K3/0 Mini
A K3/0 that could directly connect over the internet with a K3s (K3s+ or K4) is really needed. The remoterig is relatively difficult and old tech. The client server architecture like flex is using is what is needed. 73, Fred AE4ED On Thu, Feb 28, 2019 at 8:12 AM Jorge Diez - CX6VM wrote: > Hello > > any idea if will be a new control radio for remote?

[Elecraft] K3/0 headset or desk mic suggestions
I purchased a heil headset, and I’m running into a bias problem using the K3/0. I want to work the SSB NAQP remotely and need my hands to be free. Has anyone a solution to using a K3/0 with either a headset or desk mic? 73, Fred AE4ED __ 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/0, RRC-1258 MkII, DXLabSuite Commander, WSJT-X configuration
Happy Holidays, I do not know if what I am trying to do is possible. Before attempting to set up remote using K3s/0 and RRC-1258 MkII, I was using DXLab Suite and WSJT-X just fine on my K3s. I am hitting a wall when I try to use DXLab Suite plus wSJT-X with the K3s/0 and RRC-1258 MkII. Has anyone successfully done this? I have seen two remote options come up during my internet search. 1) K3s/0 remote using RRC-1258 MkII w/o PC 2) K3s/0 remote using RemoteHam software apparently w/o using RRC-1258 MkII. Ultimately, I want to do remote contesting using N1MM+ with the ability to operate SSB, CW and data. So, if anyone has information on how to configure such a setup, that would be great as well! 73, Fred AE4ED __ 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
