[Elecraft] Elecraft CW Net Announcement

Good Evening,    A warm and wet week has changed into a cold and wet week. There were a few hours of sun around sunrise, sunset, and when the clouds dropped into the valleys.  The FedEx driver had to chat for a while to enjoy the sun.  It was his first trip up through the clouds.   The sun

Re: [Elecraft] Rx-In/Out used for exteranl SDR Device?

To use the RxAnt In/Out BNC connectors in the KXV3, you need to select the RX Ant from the front panel RX Ant switch. This means you need a jumper between RX Ant Out and RX Ant In to feed the RX in the K3, with a tee or splitter to feed signal to the SDR. If you do not select RX Ant, the only

Re: [Elecraft] Rx-In/Out used for exteranl SDR Device?

5 S-units is way too much drop for even a simple T-connector. I see almost the same loss whether I use a "real" splitter or a simple T-connector. Bob, you say "right upper rear" which doesn't sound right. That's approximately where the LINE IN-OUT phone jacks are located. Are you sure you didn't

Re: [Elecraft] Rx-In/Out used for exteranl SDR Device?

Did you use a splitter in the loop between RX out and RX in?  Loss with a splitter is more on the order of 3-4 dB. 73, Pete N4ZR Check out the new Reverse Beacon Network web server at . For spots, please use your favorite "retail" DX cluster. On 12/4/2021 3:41

[Elecraft] Rx-In/Out used for exteranl SDR Device?

Hello Elecraft List I recently got my K3 back from Elecraft. They'd upgraded it to K3s. I used to be able to run a cable from the Rx in out area on the right-upper-rear as I face it. That gave me antenna without the threat of RF into my SDRPlay. I tried Rx In and Out then pressing RX on teh

Re: [Elecraft] K1 LCD BaCKLIGHT

Sounds pretty similar to what I did.  The white rectangle in my photo is a piece of white sticker vinyl stuck to the PCB under the area where the LCD mounts  The two LEDs were sanded down with a Dremel tool and sanding drum to get the light to diffuse and also to make them small enough to

Re: [Elecraft] K1 LCD BaCKLIGHT

I made my own backlight for my K1 before the Elecraft version came out.  It was actually more of a sidelight, but it works fine.  I took a white LED, sanded the plastic case to make it more diffusive, and fed it off the 12 volt buss with a current source made from a gate-source connected

Re: [Elecraft] Elecraft K1 VFO reading

As a follow up to Don's great advice, I had a few spare moments today while I was relaxing from some physical labour so decided to crack open the wee little K1 and take his advice. I compressed the turns on L1 (whoa, is it ever finicky!) but after some playing around my tuning is now: 20m- -

Re: [Elecraft] K3 Auto ATU Problem

Tom, Does the problem you describe occur on each of the ANT1 and ANT2 ports on the KAT3 output when the ports are terminated in a good 50 ohm power load? Have you checked the K3 ANT selection when the KAT3 is installed to be sure that the port to which your 50 ohm load is attached is the one

Re: [Elecraft] K3 Auto ATU Problem

The KAT3 performs well at 10 watts, lower output levels may not get consistent results. Ditto the KAT500 and KPA1500 tuners. 73, Rick NK7I On 12/4/2021 8:58 AM, Dave wrote: Hi Tom, In your initial post, you failed to state the power level of your failed autotune event. Hence why my

Re: [Elecraft] K3 Auto ATU Problem

Hi Tom, In your initial post, you failed to state the power level of your failed autotune event. Hence why my question did not ask what the tuning level needed for the K3 to trigger was, but at what power level you were performing your failed autotuning event at. My thinking was that you

Re: [Elecraft] K1 LCD BaCKLIGHT

I did a backlight on my K1 ~20 years ago that worked out well. The key was getting a transreflective LCD panel so the light would show through. The original panel was opaque.  Here's a couple of pix: https://www.dropbox.com/s/pu01s46xylba2se/100_0047.JPG?dl=0

Re: [Elecraft] K1 LCD BaCKLIGHT

Ken, The K1 LCD backlight is no longer possible.  The original used half of the K2 backlight strip which is no longer available and the new K2 strip is too thick to fit under the K1 LCD. 73, Don W3FPR On 12/3/2021 11:39 PM, Ken Brown wrote: Need the best modifications for back lighting

[Elecraft] K3 Auto ATU Problem

Dave (NK7Z), The K3 performs its auto-tune sequence at a power output of 5 watts I believe. 73, Tom G3OLB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post:
