RRA EP 30 Embarrassing Ham Nets

Embarrassing Ham Nets

Hello everybody, first I would like to apologize for the amount of time it has been since the last RRA. I recently found myself in the hospital and have been having to spend a tremendous amount of time recuperating but we are hoping to get the show back on track so that you can hear my melodious voice regularly.

We recently did a live recording on the Resonant Frequency Discord server and we would like everybody to join us for future recording sessions click this link and it will take you right over there. Do the verification and and you will be ready to go. The server is located at

This time I wanted to talk a few minutes about something I found very disturbing recently. That is to say “What The Hell Has Happened To Amateur Radio Nets?”

I am not talking about the old and well established nets but the new and improved idiotic ragchew sessions that are being spoon fed to the new operators because they don’t know any better. Listen a bit and form your own opinion.

“Goin’ On a Date With Santa” by Dr. Elmo, from the album “Up Your Chimney”

Buzzword: 16:16 Superheterodyne, presented by Tim Sutton, KI6BGE.

Song: 22:34 “Don’t Want No Bones for Christmas (I Want An Electric Guitar)” by Paul Austin Kelly, from the album “Don’t Want No Bones for Christmas”,

Topic: 25:54 Batteries: Gel cells and lithium ion.

Gel cells are a type of valve-regulated, lead-acid (VRLA) batteries. They have a pressure-relief valve to allow venting of hydrogen during overcharging, and a gelled electrolyte. Theyhave a greater resistance to extreme temperatures, shock, and vibration than typical wet-cellbatteries like the common car battery.(Contrary to what Richard says, hydrogen is a colorless, odorless gas. The “rotten egg” smellfrom an over-charging car battery is due to the creation of hydrogen sulfide gas, H2S. -Ed.) Lithium Ion batteries.Most of the newer electronics, like laptops, handheld radio, etc., has Lithium ion batteriesdue to their energy to weight ratio, and no memory effect. They also have a low self-dischargerate and are lighter than other types. Their service life depends on the time of manufacture,regardless of number of charge/discharge cycles. The internal resistance is higher than mostof the other chemistries.

Song: 41:44 “Send Me a Wife for Christmas” by Dr. Elmo, from the album “Grandma Got Run Over By A Reindeer”,

Conclusion: 44:42 Listen to Linux in the Ham Shack, too!Happy Holidays!

Closing song: 46:42 “Jingle Bells (Dan the Automator Remix)” by Dean Martin, from the album “Christmas Remixed -Holiday Classics Re-Grooved”
