The second Saturday Morse Code Tutor build event was also well attended.

This posting includes pictures from the second Morse Code Tutor build event along with Cliff, N4CCB’s video of Dave, KI4PSR demonstrating the steps involved in the build! Links to the schematics, parts information etc. are included as well.

This past Saturday saw a number of WCARES members take part in the first of two Morse Code Tutor build sessions coordinated by Dave, KI4PSR and Cliff, N4CCB. Dave put together a very nice kit of parts which included an update of the W8BH version of the W8TEE Morse Code Tutor adding a very nice printed circuit board and 3D-printed case. Some members soldered their kits while others assembled boards Dave had pre-soldered, wired and tested!

For those that have signed up, the second build session will be this coming Saturday, Sept. 21st at the EOC.

Pictures from the first session are included below.

Inspired by the recent presentation on Windoms, Dave, KI4PSR with the help of Jon, KK4AIZ, Rob, KM4SOA , Paul, KM4PT and Doug, W4DML, built and tested the design during this past Tuesday’s Portable Ops. Dave said the SWR was great, just as described by Ted, W3TB.

From Jon:
“Station was Icom 7300, with battery and solar panels. We were able to tune 20, 40, 80, & 17. I made one contact into Western Pennsylvania; on 7.255 – missed NC callsign. Got a 5.6 report!”

Dave Matthews, KI4PSR gave a talk at a recent Chew & Chat. The talk covered receiver designs over time and included discussion of the Tayloe detector.

Randy Moore, KK4SRO, our EC, has uploaded a video of Dave’s talk to Youtube and Dave’s slides are available as well:
