Re: [Elecraft] K3/P3 issue

In a recent message, Alan writes So you would expect it to read 3 dB lower (half the power), which is half an S unit. This is something that has always puzzled me, Alan. I agree that -3dB is half the power (in watts), but S-meter calibration is related to (micro)voltage.

Re: [Elecraft] K3/P3 issue

3 dB? I've seen an S unit described as 6 dB -- double the *voltage*, or four times the power. Or in recent years some radios do 5 dB -- keep a linear string of LED's where over S9 is in 5 dB increments and below S9 is in 5 dB S units. Your assertion is the first time I have ever heard an S unit

[Elecraft] K3/P3 issue

Perhaps I missed the answer to this... My SVGA external monitor shows signals about 1/2 to one S unit lower than my P3 does on the native screen... What am I missing? If I use Peak Hold, there is a clear 1/2 to one S-Unit difference in teh display height... -- Thanks and 73's, For equipment,

Re: [Elecraft] K3/P3 issue

For a continuous CW tone, the level should be the same on the P3 and the external monitor. For SSB, the SVGA display should read 1/2 S-unit lower. The reason is that, unlike CW, an SSB signal is spread out in frequency. Since the SVGA monitor has twice the frequency resolution than the P3

Re: [Elecraft] K3/P3 issue--no signals

I have similar issue. Just built the P3 and it worked immediately. I shut down and returned a few hours later and no signals. It's like the IF is no longer getting to the P3. Weird. Hope someone has the fix soon. Pete WK8S -- View this message in context:

Re: [Elecraft] K3/P3 issue--no signals

Pete, I have experienced the same thing. It seems the IF BNC connector on back of the rig is a bit touchy and I have difficulty getting a really solid connection. If I move the rig around any at all the BNC disconnects. Playing with the connector seems to get me up and running again.

Re: [Elecraft] K3/P3 issue--no signals

I'm sorry I didn't post the fix. As it turned out, the RF board holding the BNC jacks was bad. Elecraft sent a replacement and I was up and running again. 73, Gary W7TEA - 73, Gary W7TEA K3 #1001, #5763 -- View this message in context:

Re-seated the internal coax to the P3 RF bd. That seems to have fixed the problem, at least for now. We'll see if its a permanent fix. Pete WK8S Subject: Re: [Elecraft] K3/P3 issue--no signals To: elecraft@mailman.qth.net Message-ID: 1324131709649-7104107.p...@n2.nabble.com Content-Type

[Elecraft] K3/P3 issue--no signals

Left my rig for a couple of hours this morning and when I returned, my P3 was no longer reading band signals. It is as if it is only hearing internal rx noise with the grass well below S0 and RefCal cranked up to 145 and beyond. The K3 seems to hearing just fine. Have restarted both units,
