Last day of 2024, 22:46 and I just launched #cwmouse This is my high precision 3d printed #iambic #paddle . It is based on mouse micro-switches, magnets, quad ball bearings and 3d printed case along with integrated 3ft cable. All comfortably fitting in a palm of your hand and weighting only 2.1oz (60g). If interested, drop by my web page and order one! #amateurradio #cw #cwkey #ham #hamradio https://cwmouse.com/ cwmouse.com/

#cwmorse aluminium #cw key feels great, but I’m not happy with missed symbols. I suspect it is sensitive to debris in contacts. I decided to design my own using #3dprinting . Four ball bearings for paddles, magnetic tension and top secret switching components :) I intend to make more of these if youtube key reviewers give it favorable feedback.It is designed for quick no post processing assembly. I learned a lot to go from “one time piece” to no-post processing.

Morserino-32 production is ending due to parts unavailability. This is a fully self contained, battery powered #cw trainer, keyer and decoder with wifi and lora connectivity. Even includes capacitive paddles!! I’m using it daily to pick up and practice my cw for few minutes at a time. I’m looking forward to building it’s successor kit :)

No more excuses, I’m starting my #qrplabs #qcx mini build tonight :) The remaining excuse WAS that my new #40m #efhw element and transformer were not tuned. I finally purchased a #nanovna -h and got below 1.2 VSWR in the center of #CW band :) Also used my efhw #3dp insulator to allow quick returning (design similar to tent guy lines lock). Out of curiosity I checked this ant on 10m but it was ~3. It will be easier to make a 10m than go for linked setup.

I like the concept of capacitive paddles, but the #morserino -32 execution is somewhat lacking as the PCB paddles wiggle their way out of their slots during operation. The remedy is simple, a small 3d printed block to slide between case and between paddles to align, stabilize and prevent shifting. It feels so precise when sending #cw with this improved setup - you feel touching the paddle, zero movement and it responds.

As I’m learning #CW I continue to experiment with #SDR receive and change my setup to improve usability. I’m using 40m #EFHW on a 26ft fishing pole as a inverted-V mast. While receive-only for now, I used my 25W EFHW transformer (from before selling G90) but find it bulky. I bought and build KM4CFT’s 5W efhw transformer and configured it with bullet connectors and creative use of paracord and zip-ties for anchoring the antenna wire. I also built 8-winder to avoid tangles and quick setup.

Got a fancy #cwmorse .us machined aluminum #cw key. Dual paddle, ball bearings, magnetic tension and base, and fully adjustable. Very precise and a big upgrade from the 3d printed #cwmorse unit. I started with their single 3dp paddle and added stronger springs but it didn’t feel consistent. This one DOES! Some downsides: loud contact clicks, need to hold horizontal due to heavy arms, can’t touch tension adjustment screw when operating. Rating it 8 while #3dp was 4.

I’m learning #cw with #morserino32 + a sideswiper for simplicity. Now that I’m pretty good at sending at 18wpm (my letter spacing stretches as I get fatigued) I’m thinking of getting a dual paddle and I am exploring different keyer modes. Ran across this awesome video highlighting #ultimatic vs #iambic A and B. For somebody who only used a #sideswiper , I’m sold + #morserino supports it! Q. aside from HF radios keyer support, any downsides? #hamradio #amateurradio https://youtu.be/Hn4j2nfdKNE youtu.be/Hn4j2nfdKNE

I setup my RTL-SDR-v3 for HF on #Linux using #SDR ++. Used a 40m EFHW badly strung 5ft off the ground around the garden in #NVIS configuration. I was able to pick up CW from CA, NV, AZ and CA<->TX SSB. Also FT8 and JS8. Problem: on the #CW end of the band, I’m picking up an AM station which I assume is coming in via IF. Do I need real ground? or better common mode choke? Please advise. Having sold my bulky G90, I will use SDR, learn CW and get QCX once I can “hear” :)

#Introduction #cq for #amateurradio and #hamradio . I’m Technician into #aprs , #cw and #emcomm on #hf . My equipment is Kenwood TH20A 2M in my car with magmount and #xiegu #g90 with #efhw on #battery #solar #power (the emcomm bit). I also have a 1W tracker in my #aircraft . The furthest I made SSB contacts from #california is #mississippi . On #js8 #js8call I easily make contacts into eastern seaboard. Current projects are learning #cw setting up a permanent #antenna and getting my #general .
