If a build-from-kit solution would work for you, I can recommend two kits from qrp-labs.com . This is the ProgRock "triple programmable crystal" kit, which can be GPS-disciplined by the QLG-1 GPS receiver. I've built these (and other) kits from QRP Labs: high quality,

[Elecraft] Review of W8FGU Services, LLC

Dave Van Wallaghen is who I was referred to by Elecraft for a thorny problem with my K2. A number of knowledgeable people had looked at the problem and given up. Not only did Dave spend a long time with me on email exchanges, trying to help me fix the problem on my own, but once he got the

Re: [Elecraft] 10 MHz reference osc. suggestion?

I use the Dual Output part from Leo Bodnar so I can set one at 10MHz, and the other on a different frequency for use with my VNA. Additionally, I use Bodnar's NTP Server to serve extremely accurate time to everything that I own with an electronically settable clock, including my K3s

Yes. Headphone to mic distance gets short and feedback can happen from leakage. Sent from my iPhone ...nr4c. bill > On Feb 5, 2020, at 10:44 AM, Richard Corfield > wrote: > >  > Even with monitor running into headphones? > > I was running the contest with monitor off at first, but I

Re: [Elecraft] 10 MHz reference osc. suggestion?

I have a Bodnar dual output GPSDO although I don't use it on my K3S.  Be advised that the software is very clunky and while you can get two different frequencies out, there are limitations on what they can be. Frankly, I don't know why you would want something like this for the K3(S).  The

Re: [Elecraft] 10 MHz reference osc. suggestion?

I used this one from Geppetto Electronics when I last ran temperature compensation on my KX3: https://www.tindie.com/products/nsayer/gps-disciplined-ocxo/. One advantage is that it also produces NMEA output along with PPS, so one could build a GPS-based NTP server at some point in the future. It

Re: [Elecraft] RF feedback into MH3 mic with KX3 on 2m

The metal shield cover on the 2m module was not flat but slightly raised at the edge. I have pressed this back on and the problem seems cleared. So I guess it was contacting or coming close to the circuit board on the control module, perhaps that giving the feedback loop for RF. Question is -

Re: [Elecraft] RF feedback into MH3 mic with KX3 on 2m

I've done some further tests and proven the problem is with the MH3. So I'll have to take that apart and look for the problem. The radio is fine with little earbuds/mic plugged in via splitter cable. Swap out the mic on the earbuds with the MH3 and leave all the rest the same and it goes wrong.

Hi Gary, Here is the one I use: http://www.leobodnar.com/shop/index.php?main_page=product_info=107_id=234 It feeds my K3 and I also use the other port to calibrate the oscillator for the main MCU on all the K2's I service. 73, Dave, W8FGU On 2/5/2020 2:43:46 PM, "Gary Peterson" wrote:

Does anyone have any recommendations for a particular 10 MHz GPS disciplined oscillator that would work well as an external reference for a K3S? I might also use a GPSDO as an external time base for my frequency counter. Either recommendations or products one should avoid would be most

Re: [Elecraft] KPA3 in K3S mostly not working

If it is intermittent, then check for the KPA3A not being seated all the way down (pull Fan panel, 4 screws and inspect). Or it could be the relay on the KPAIO3A riser board. To confirm; click above and below 12W a bunch of times, if occasionally the RX comes and goes, it is that relay.

I had issues with RF feedback on the MH3 during the UKAC SSB 2m contest last night. It seemed intermittent. Result was terrible noise in Monitor output (my headphones) and to the other station, so it affects the audio input. With experiments at the time and this morning: - Occurs when RF
