Re: [Elecraft] K3 Speaker Amp Protection

Joe, you may be right, but the description of the Revision C mod says, This modification protects the K3's audio amplifier if either speaker output is connected to a short circuit or very low impedance load. Since I've made this mod, I'd like (hope) to know that this protects the audio amp.

Re: [Elecraft] K3 Speaker Amp Protection

Don, Joe -- Don, You missed my point. of confusion, Joe said open circuit. Yep, I do use a stereo plug, thus I have an right channel open circuit when I connect an external speaker. But there seems to be something else that Joe is warning against other than open circuit. Referring to

Re: [Elecraft] Help on Configuration

Hi Deane - for what it's worth. I think for most non-critical (non-contest, non-DX) users, the K3 standard 2.7 kHz SSB filter does a good job for CW and SSB modes. The K3 DSP software allows you to narrow the bandwidth for CW to 500 Hz or less. The DSP works much better than the Yaesu and

Todd - try the SUB (sub-receiver button). It links the VFOs. This feature appeared in a software update described as ... VFO LINKING: Holding the SUB switch links/unlinks the two VFOs. When linked, VFO A is the master; turning it moves both VFOs the same amount. VFO B can be set to

[Elecraft] Using Heil ICM mic with K2

[Elecraft] K3 Convergence

Speaking of the K3's computer interface - I've noticed that no K3 responses are generated for the following K3 front panel buttons: RIT, XIT, AGC OFF, DUAL PB, NB, NR and NTCH. Also, the response for XFIL is always FW. I am using the most recent firmware.

[Elecraft] K3 Programming questions

I've been playing with the K3 remote control commands. I've enabled the interface with a AI2; command expecting to see FA responses when I change the VFO A frequency. I do see the FA responses, however they are not continuous. As I tune VFO A, there is a delay in the FA response and there

[Elecraft] Remotely controlling a K2

Here's a configuration that may work. It incorporates a K2 radio control program running on your Mac and a means to control you Mac via the Internet from your Windows operating system PCs. (You've got the audio part figured out.) 1) Install a K2 control program on you Mac. This will allow

[Elecraft] MH2 handmicrophones

Ron - somewhere way back (months ago) there was a comment by one of the Elecraft folks that the new HM2 has been improved in terms of interior mechanical construction. From that comment, I inferred that electrically they are the same. Barry, WK2S

[Elecraft] K3 Covers

I just received a K3 cover I ordered from www.compucover.com. They make covers in custom sizes. Not having my K3 yet, I guessed at the size from the dimensions in the FAQ. Wish I could confirm that it fits. Their price was $14.95 plus $12.00 shipping (I thought the shipping was a bit high,

[Elecraft] K2 mike question...

Steve - I believe the answer to your question, Can the Heil GM-4 work with the 10k hooked up from AF to 5V? is yes. The Heil Icom cables for the GM microphones have a capacitor that isolates the 5V from the GM microphone element. See the description of the Icom setup on the Heil web site -

[Elecraft] K3 microphone wiring ?

Thanks for the additional information in the FAQ about microphones. But I still have a question. The wiring for the K2 MD-2, MH-2 microphones and the Heil headset has 5V applied to pin 1 through a 5.6k resistor. Will the K3 be able to supply 5V on pin 1 through a 5k resistor via a jumper or
