Avery Davis & Amateur Radio and Electronics

Updated 2008 June 14

Callsign WB4RTP
Before I moved to Tucson, AZ, I frequented the
NFARL 145.47 or the BSRG 146.655 MHz repeaters in Marietta, GA.
Now, I am a member of the
Catalina Radio Club in Tucson, AZ
I am also a member of the
Tucson Amateur Packet Radio (TAPR) organization.

For Field-Day logging, I have been using the WR9R Field Day Logger software application.  
I have created number of DOS batch files to ease the use of WR9R’s software and collected them in a ZIP archive  CLICK HERE  

Here is a construction project for a Speaker to Headphone Adapter With Splitter.

Recently, I have written an article entitled The Closed Repeater Issue: A Remedy Proposal
Here are some links on this issue:
The Closed Repeater Issue
BSRG, an example of a repeater network that is NOT closed.
UPARC, another example of a repeater network that is NOT closed.
The Closed Repeater Coordination Society
Las Vegas Repeater Association - Closed Repeater Discussion

Here is a nifty code practice program called ZZCODE. Click the button to download ZZCODE.ZIP, which contains the source code, ZZCODE.BAS, and an MS-DOS compiled executable, ZZCODE.EXE. These files must be extracted from the ZZCODE.ZIP archive using PKUNZIP version 2.04g.

Also, look at my comments on the "ARRL-Recommended" power connector.

ALERT! Contact your Congressman to keep GPS usable!

Electronics Engineering:
Digital, analog and RF circuit design.
I now work for
Raytheon Systems Company in Tucson, Arizona. Up until May of 1998, I worked for Electro Systems International.
I am not currently looking for employment opportunities, so headhunters please don’t waste your time.
