The scores are in! The N1FD team placed #1 in Area 1 Multi-Op category in the ARRL Rookie Roundup CW! We have won the Area 1 Multi-Op category in all three Rookie Roundup contests this year. The complete results can be found here.
Congratulations to Abby, KC1FFX and Jamey KC1ENX, who operated in the contest!
The N1FD Contest Team operated in the final Rookie Roundup of the year – the ARRL Rookie Roundup CW. Jamey, KC1ENX and Abby KC1FFX operated as a Multi-Op team using the N1FD callsign at the QTH of AB1OC and AB1QB.
The CW contest proved to be a great way to improve the CW skills of the rookies as well as the Elmers! It was the perfect follow-on to the Morse Code Class held earlier this year.
Abby and Jamey made a total of 21 QSOs in the contest, including one with another rookie from Alberta, Canada. Most of the activity was on the 20m band with a few contacts on 40m.
We all had a great time in the contest and are looking forward to working another CW contest soon.
We’re also looking forward to the next Rookie Roundup, the SSB contest which will be on April 17. We invite all of the new hams in the club to join us for the SSB version of the contest.

Below is my Arduino based CW iambic keyer. I wanted to be able to change my WPM on the fly using a potentiometer.
I had some LED 7 segment displays that would be perfect for this application. The issue then becomes how do I not use up all of my IOs… Below is the IC that I used.
Microchip Technology MCP23017-E/SP
This IC is much cheaper than a multiplexing IC for 8 digits.
Now I have plenty of IOs left over for buttons to Call CQ, give my callsign, and QTH etc.
If I wanted, I can keep adding more ICs (up to 8 total or 128 IOs!!) as needed just as long as I set a new unique address to each IC when using I2C.
I have also used this IC with an LCD display that uses up IOs quickly.
