[Elecraft] Elecraft K1 Noise Blanker

I recently had the question on the Elecraft K1. - looking to buy an already built K1 Noise Blanker KNB1. And here is the best answer to adding a noise blanker. http://www.westmountainradio.com/product_info.php?products_id=clr_dsp CLRdsp ClearSpeech® DSP Noise Reduction Processor $220 plus

[Elecraft] P3 SVGA card repair

Good afternoon, My P3 was just returned from Elecraft, where I sent it for repair (lightning). The SVGA card was in the box with paperwork saying the U502 voltage regulator was replaced, but the unit was unrepairable. Is there anyone on the list who would be willing to try and repair it? I

Re: [Elecraft] K3 ATU Problem

HI, After a bit of button pressing I have noticed the following: When doing a first tune using the internal ATU the tuning power is a set 5W. Immediately doing an extended tune the tuning power toggles to 10W. It does indeed flash up in the VFO B window whilst tuning is in progress. This is

[Elecraft] K3 ATU Problem

PS  When using the tuner in the KPA1500 with the K3, it gets the 10 watts that I have as my default.  I've not tested to see if that can be changed to any other value. I also attempted an ATU tune on the K3 into a dummy load, it's too fast for power to be displayed.  ;-) 73, Rick NK7I

Re: [Elecraft] K3 ATU Problem

On my K3, (Tech Mode on, just for clarity): Config | TUN PWR  is set at 10.0 watts.  If I want it set at another level, I turn the main VFO knob to set that level. I just tested that into a dummy load after setting the output per above to 9 watts and got 9 watts out (since reset to my

[Elecraft] K3 ATU Problem

*You can set TUN PWR in the K3 Config Menu to something other than 5 watts.73,DrewAF2Z* Drew, Page 60 of K3 Owner's Manual states: "TUN PWR Note 1: *TUN PWR* does not pertain to *ATU TUNE, *which always uses 5 or 10 W and is internally controlled" Does anyone know how to change the 'internal

Re: [Elecraft] K2 and N1MM+

I made a simple modification to allow this. I don't use ALC, so I repurposed the ALC pin in the interface connector. On the control board I added two 1n4148 diodes, cathodes to the former ALC pin of the connector and anodes to the dit and dah lines that go to the paddle. Then I connected that

Re: [Elecraft] K2 and N1MM+

The N1MM documentation shows a simple circuit for keying via DTR/RTS or parallel port using a 1K resistor and an NPN transistor (2N or equivalent): https://n1mmwp.hamdocs.com/setup/interfacing/ > On Dec 8, 2021, at 9:44 AM, Bill Coleman wrote: > > > >> On Dec 7, 2021, at 4:13 PM,

Re: [Elecraft] K2 and N1MM+

Jim, Since the K2 has a positive key voltage, an NPN transistor is necessary. (eg 2N, 2N3904, etc) Alternatively, one could use an enhancement-mode N-channel FET (eg 2N7000, etc). > On Dec 7, 2021, at 5:25 PM, Jim Brown wrote: > > On 12/7/2021 1:13 PM, eda...@aya.yale.edu wrote: >> Can

Re: [Elecraft] K2 and N1MM+

Hi Ted, For keying my K2 I use a special CW-usb cable and that works fine in N1MM You can find this cable on Alieexpress or Ebay 73 Jos Pa3hgx
