[Elecraft] Looking for K2 PCB

I would like to do some experiments with the K2 VFO. If someone has a dead (or unbuilt) K2 VFO/PLL PCB, I would be interested in it. Trades and/or a small amount of cash would be available. This is strictly for personal interest - I have attempted to replicate K2 VFO performance using ugly construc

[Elecraft] K1 For Sale

This K1 is a GREAT radio. I'm always impressed by it when I've taken it out camping, or on field day, or when I'm at home. The ATU matches just about anything you can put in the trees! This is a 2-band version (70Khz band spread - can be changed to 150Khz) (20 and 40 mtrs installed) with an extra K

[Elecraft] K3/0 documentation?

Hi Wayne, Eric & all, before ordering a K3/0 I would like to take a look into the manuals, i.e. builders guide, etc. to see what is different to the K3/10 or K3/100 and what connections are needed. Haven't found it on the website yet - any time schedule when it will be available? Tnx! Vy 73, O

[Elecraft] Firmware update process stalled K3

I wanted to install the latest firmware beta release (4.47). The process started, on the K3 display MCU LD appeared, but after a while the message appeared, that the update failed. The K3 stayed in the MCU LD mode and the K3 utility showed that there is a communication problem with the COM port.

Re: [Elecraft] Low sensitivity on K2...

Robin, What filter were you using when doing the sensitivity measurements? Did you use the same filter width for each? If they both have the KSB2 installed, try doing a comparison with the OP1 filter selected. Is one K2 above SN 3000 and the other below 3000? If so, yes there may be differe

[Elecraft] Low sensitivity on K2...

I have two K2s, and I find on one of them that the sensitivity is much lower. I see this when doing a test with an XG1 signal generator. The problem is that the "low sensitivity" rig is one that I bought built, while the one that works fine is a rig I built myself. I have tried to reallign the rig

[Elecraft] Stereo phone plug on back of K3

Back around the time I got my K3 (serial number #3799) there were several other K3 owners who had problems (like shorted audio circuit or something like that) when they put a mono 3.5 mm plug into the stereo rear panel phones outlet. I remember the warning: use stereo only for rear panel phones

[Elecraft] Great decision on K3

It was November last year when I decided on a "fully loaded" slightly used K3 versus a FTDX5000 and I am so stoked that I made that decision. I still monitor the user group for the high end Yaesu 5K because I am still interested in understand how the two rigs compare. One of today's posting wa

Re: [Elecraft] K3 Voltage drop

Joel, Measure the voltage drop right at the power supply terminals - that will tell you how much of that total voltage drop is due to the power supply. The rest is in the wire and connectors - there are 12 connectors if your PowerPole distribution box has fuses, and 8 connectors if no fuses.

Re: [Elecraft] K3 Voltage drop

Ron, I didn't think to look at that last night, but I am testing it now into a dummy load at 50W. I am using an MFJ-4125 with about 18" of #10 "zip cord." This goes to a PowerPole DC distribution panel and there is another run of about 30" of #10 to the K3. On receive, I have 13.4 - 13.5VDC
