RV Service Net Reception at WA5MLF

During the last half-hour of yesterday's RV Service Net the signal from W4UOA was solid at Baton Rouge. The distance from my station to W4UOA is 430 miles.

Below is a screen shot captured at 0751 CDT, while W4BXI was transmitting on 7191 kHz  from W4UOA. Another strong signal can be seen below 7188 kHz.

A little earlier (0728 CDT) I recorded KB0BH checking into the Net and acknowledged by W4BXI. The recording (click here) was made from my Flex-3000 transceiver in Baton Rouge.

Open Wire and TPARCA

Click above to enlarge image.
Here's the cover of the March 1989 issue of Open Wire, the news bulletin of TPARCA. Note that the dial-up bulletin board system was in use at the time. For a bit of nostalgia you might like to listen to the sound of a dial-up modem connecting on this YouTube video. It offers explanations and waveform views of each stage of the connection process, starting with dial tone -- something that young folks rarely hear.













Among the contents of this issue was the following certificate from the ARRL:

   

The back page of the issue includes the Telephone Pioneers emblem:


N4AHJ has provided a large volume of historical Open Wire and TPARCA material that I can make available to any interested members.
