QRPer Notes: sBITX Prototype, Updated Icom Control Software, and Jim Stafford (W4QO) SK

Because I receive so many tips from readers here on QRPer, I wanted way to share them in a concise newsletter format.  To that end, welcome to QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!


sBitx Prototype

Many thanks to Pete (WB9FLW) who sends a link to this article on It’s Ham Radio:

Ashhar Farhan VU2ESE demonstrated Hfsignals upcoming SDR transceiver – sBitx today at Lamakaan Amateur Radio Meet.

VU2ESE was working on this SDR Prototype for some time now. sBitx is the latest iteration of the popular homebrewer transceiver Bitx series started a couple of years by Farhan.

Keynotes

    1. Raspberry Pi instead of Arduino – No more Arduino Code, sBitx code is written from the scratch for Raspberry Pi.
    2. Power Output: 40 Watt ~ 20 Meters, 15 Meters ~ 25 Watts, 10 Meters ~ 10 Watts
    3. Ditched IRF 510 for IRF Z24N for Finals
    4. $250 for global buyers. Indian buyers would have to wait for now.
    5. Display: 7″ Raspberry Pi Stock Display
    6. Easy Digital Modes – FT8, RTTY, Free DV etc. No extra wiring is required.
    7. Simple Integration with existing Linux Desktop or Remote Login via SSH or VNC

This week, we learned that Jim (W4QO)–a noted fellow in our QRP world–passed away.

Jeff Davis (KE9V) wrote a wonderful tribute on his blog. Jeff writes:

Jim Stafford, W4QO became a Silent Key yesterday. That news wasn’t unexpected, I had been closely following the North Georgia QRP mailing list these last few weeks dreading the announcement that arrived yesterday morning.

I had known Jim for more than 20 years. We first met in the late 90’s during a Four Days in May event back when the conference took place at the old hotel south of Dayton. I think we hit it off because we both were native Hoosiers, but his infectious enthusiasm for the hobby made everyone want to be around him.

He became my guide into the world of low-power radio and over the following years we regularly renewed our friendship on the air, via email, and in person almost every year during FDIM at Dayton. [Continue reading on Jeff’s blog…]

  1. Jim , W4 Quaker Oats was one of the most generous Hams I have ever met. He is the reason I got into CW and I am not the only one he influenced. He will be greatly missed by everyone who ever had the privilege to meet him.

    73 my friend dit… dit…

    Rin,
    W4RIN
