Re: [Elecraft] P3 and averaging - dillemma or no problem?

I have raised this issue with Alan (N1AL), on SSB signals below about S9 they average out to little more than a few dB above the noise floor yet look quite good with the peak enabled. Like you suggest a peak facility where the reading decays after a few seconds would be very useful, in

Re: [Elecraft] K2 switch replacement

Paul, If you do not have professional de-soldering equipment, cut the leads of the switch and remove the pieces one at a time. Do not try to salvage the old switch, that does not make sense considering the value of the rest of the board. 73, Don W3FPR On 1/17/2011 11:18 AM, Paul Huff

Re: [Elecraft] P3 VFO B Tracking

Jim, I am not sure what you mean by track. The P3 will show the VFO B frequency with the magenta cursor. See Using Cursors in the P3 manual. If you mean -- display the output of the subRX, that is not possible without a mod to the SubRX - there is no IF output from the sub. 73, Don W3FPR

[Elecraft] K2 speaker/headphones switching.

Just bought a new K2 #4913. All is great, however, inserting a headphone doesn't cut off the speaker. The headphone plug is a standard 3.5 mm plug. The schematics show the plug should cut the speaker. Is there an internal parameter that needs setting? If not what's the easy way to access

Re: [Elecraft] K2 speaker/headphones switching.

Chris, In all probability, the little plastic lever which operates the switch inside the headphone jack has broken. It usually fails with no speaker, but it can fail either way. It is a bit of a pain, but you can shut off the speaker by plugging an empty jack into the external speaker jack

[Elecraft] [K3] CW transmit filter bandwith

I was reading W8JI's article http://www.w8ji.com/what_causes_clicks.htm but see that the advice in it (use a narrower filter than an SSB filter for transmitting CW) conflicts with the K3 manual, which says: Rotate VFO A to select a CW transmit filter (2.7 or 2.8 kHz). Note: Key clicks may result

Re: [Elecraft] [K3] CW transmit filter bandwith

Graham, Tom W8JI was dealing with analog transceivers when that was written. The K3 generates the signal digitally in the DSP portion of the transceiver, so many of those old rules of thumb for analog radios do not apply to the K3. As Guy has said many times on this reflector, This is not

Re: [Elecraft] [K3] CW transmit filter bandwith

I am wondering why a narrow filter can cause key clicks? One cause is related to the placement of the CW frequency in relation to the filter passband. If skewed to the edge of a sharp filter, a severely distorted waveform will develop. A CW waveform is a quasi square wave and replication

[Elecraft] K3/K144XV/P3 Signal Strength Readings

Re: [Elecraft] P3 S meter variance

My K3 S-meter and P-3 show identical S-9/S-3 readings at 50 uV and 1uV with an XG-2 on 40M. Sideband and particularly band noise are different as noted in previous posts for obvious reasons. If your readings are miles apart, time to check calibration of both units. I went through the

Re: [Elecraft] [K3] CW transmit filter bandwith

Probably the biggest variant in how to think about this is that in an analog transmitter you start with a badly flawed signal which needs to be cleaned up. The filter attenuates sideband energy (clicks) from a waveform which was already distorted at the point where the RF was keyed. In the K3
