Important announcement regarding N5CST / KD5WVV packet system.

Effective immediately, the Tulsa Digital Radio Club has severed all radio and internet ties with the Poteau, OK N5CST packet BBS system operated by Kevin Davidson KD5WVV.  He is also no longer a member of our organization.

We received information this morning that Mr. Davidson was arrested June 15th.  The press release from the arresting police department outlines a previous criminal conviction that we were unaware of until this morning.  The nature of the conviction classifies Mr. Davidson as a potential danger to the general public and falls outside of the bounds of acceptable membership behavior for the TDRC.

None of the "social media" information exchanged for the crime of June 15th was passed through the AE5ME-15 BBS system and we have extensive filtering safeguards to prevent that from occurring.  The AE5ME-15 system will continue to operate with our affiliate in Magnolia, AR. and other clients in Oklahoma, Missouri, and Western Arkansas.

The leadership of the TDRC will be meeting in the near future to determine additional steps need to be taken to prevent a membership situation such as this from happening in the future.  No further announcements will be made regarding this deeply troubling matter, but anyone is welcome to contact me at ae5me at if you have questions.

New opportunity for SWL Digital reception!

From Kim Elliott at VOA:

Hello friends,

The concept of digital text modes via analog shortwave broadcast is expanding!

Beginning 8 June, The Italian Broadcasting Corporation (IBC) will add a half hour of digital text modes to its Wednesday transmission via Channel 292 in Germany, 6070 kHz.

The entire broadcast is Wednesday 2000 to 2200 UTC, with MFSK32 followed by Olivia 16-500 at 2030-2100 UTC. 

2030-2045 UTC in MFSK32 (1500 Hz): DX and media news from "Radio Passioni", Andrea Lawendel's  blog

2045-2100 UTC in Olivia 16-500 (2200 Hz): DX Italia, news from the amateur radio world

Complete schedule and updates at

Reception reports can be sent to

Outside of Europe, try reception via the University of Twente receiver in the Netherlands:

DigiDX will continue this week via Channel 292, 6070 kHz, daily (maybe not Saturday) at 0530-0600 and 1830-1900 UTC. Vatican Radio on the same frequency at those times provides a special challenge for the digital text modes. (I hope this co-channel situation can eventually be resolved.) This week Stephen has been experimenting with multiple modes transmitted simultaneously:

1500Hz - Olivia 16-500
2008Hz - Oliva 8-250
2300Hz - Olivia 4-125
2900Hz - BPSK-125

Thank you for your reports to VOA Radiogram, program 166, during the past weekend.

Comparison of the FT-817ND to the Elecraft KX-3

I am a proud owner of an FT-817 since Green County Hamfest.  Also considering the new KX-2 that Elecraft introduced at Dayton Hamvention.  The cousin to the KX-2 is the KX-3, which has been out for a while.

M0JCQ put out an excellent comparison article between the FT-817ND and Elecraft KX-3.  Not to be a spoiler, but both have their advantages and disadvantages, depending upon what you are looking to do.

What run HF QRP portable?

With the TDRC operating digital QRP for the upcoming Field Day, one question I've been asked is "why"?

M0JCQ put together an excellent article giving the top ten reasons to take ham radio portable.  And he is not just talking HTs on the local repeaters.....He's talking HF!

TDRC Meeting Saturday June 11th at 1 PM

The next Tulsa Digital Radio Club meeting will be Saturday, June 11th at 1 PM.  It will be held at the Broken Arrow Central Library at 300 W. Broadway.

We will have an intro and Q&A session regarding the Raspberry Pi computing platform.  We'll also be discussing plans for operating our club station QRP/Digital for the upcoming ARRL Field Day.  To our knowledge, it will be the only all QRP/Digital station in the area.  If you're looking for a change of pace from traditional Field Day, be sure to check it out!
Also, don't forget to check in to the statewide APRS net this weekend, which coincides with the start of the meeting at 1 PM.  We will be operating the net from the library.

Hope to see you at the meeting!
