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 https://discord.gg/3vZQNdZ79B

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.http://en.wikipedia.org/wiki/Superheterodyne_receiver

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.)http://en.wikipedia.org/wiki/Hydrogen_sulfide36:04 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"

Ni-Cad Battery Deep Dive

Opening Theme

 

01:02 Introduction

Greetings to the hams working the California forest fires.

03:10 Feedback

Tim, KI6BGE, writes about his first radio, a Yaesu FT-747GX, and his first hand-held, an FT-60R, and other rigs. He also asks about cross-band repeating through the FT-8900R in his car.

Damon, NN7B, says Richard is his ham hero, and also listens to the Linux in the Ham Shack podcast. He was having a problem downloading the first episode, but that should be sorted out now.

Joe, NE2Z, enjoys both podcasts, and made a donation. Thanks, Joe!

Bob, KB3OQY, likes the podcast and learns something new in each episode. He also made a donation.

10:43 Donations

Thanks to Joe NE2Z and Bob KB3OQY for their donations. If you find anything useful in an episode of Resonant Frequency, consider donating a dollar. That's less than a gallon of gasoline.

Song "Voodoo Queen" by Tommy Dardar, from the album "Blues Fool"

13:55 Buzzword

Memory effect - reality or myth?

If you partially discharge a nickel-cadmium battery (NiCad), and recharge it, it may "remember" that point of discharge as it's fully discharged state. The best practice is to fully discharge a NiCad battery pack before recharging, and avoid the use of rapid chargers. A related phenomenon is "lazy battery", where the battery appears to have a full charge, but becomes depleted rapidly when put to use. This is often caused by frequent overcharging, and may be cured by several deep discharge/recharge cycles.

20:29 Song

"Wasn't That Enough" by Janiva Magness, from the album "Bury Him At The Crossroads"

22:01 Topic

Nicad batteries.

This topic was suggested by several messages on the forums.

The abbreviation NiCad is a registered trademark of SAFT Corporation. Advantages: lower weight, good charging efficiency, smaller variations in terminal voltage during discharge, low internal resistance, non-critical charging condition. In theory, a nicad battery may be charged and discharged up to 1000 times.

39:06  

Comparison to Nickel-metal Hydride (NiMH)

40:42

Disadvantages: higher cost, toxicity, memory effect, and a negative temperature coefficient. Nicad cells are typically 1.2V, while alkaline cells are 1.5V.

45:11

Charging. The typical overnight charge, called a C/10 charge, is accomplished by applying 10% of the battery's total capacity for a period of 14 hours; that is, a 100 mAh battery takes 140 mAh of energy to charge.

53:53

Episode 27 Watt Elmer? Show Notes

Song: 00:00

Intro: 00:54

Feedback: 01:23

Regarding episode 25

Thomas, WC5B, says he has changed his mind about what he recommends to new hams for a first radio, based on Richards comments.

Ray, KO4RB, also talks about episode 25 and his thoughts on a handy-talk as a first radio.

Jerry, KD0BIK, of The Practical Amateur Radio Podcast disagreed with some of Richard's comments about media coverage of hurricane damage (Ike and Gustav) along the gulf coast. Richard's comments were meant to be specific to his local media.

Ray, KO4RB, also writes to thank Richard for the podcast, and extols their virtues as a tool for elmering new hams. He's also exploring Linux for use in his shack, experiments with digital modes, DStar, and more. He also made a donation!

Rich, AB6TY, says he listens as he works in the welding shop, and enjoys the information and music. He loves CW and encourages others to give it a try, and recommends FISTS and SKCC. He reminds Richard that new hams should be aware of split-frequency operations while chasing DX. He asks "What is a 'lid'?" A lid is a bad operator.

Donations: 17:25

Rich AB6TY, Ray KO4RB made donations, which allowed the purchase of a microphone, and a new machine to record the podcast. Consider a dollar per episode. Every dollar helps. Remember, we have to pay for the hosting service. shop at Amazon through the link at the website. Thanks!

19:55 Russ K5TUX and Richard released the first episode of Linux in the Ham Shack. Give it a listen

Song: 22:07 "Night Time is the Right Time" by Elvin Bishop, featuring John Nemeth & Angela Strehli, from the album "The Blues Rolls On"

Buzzword: 23:19 SWR and Watt MetersMeasures power out in watts and the SWR (standing wave ratio). Higher SWR is bad, as most modern radios will reduce their output if the SWR is too high, so it's a good idea to monitor the SWR. They can also be used to tune your wire or mobile antennas.

Song: 31:58 "What Is That You Got" by Magic Slim & the Teardrops from the album "Midnight Blues"

Topic: 34:17 How can you be a better Elmer? Elmer is the amateur radio term for a mentor. Anyone can be an Elmer. It just takes the desire to share what you know with someone else. It does take patience. Talk up the hobby with other folks. Teach a class. Get involved with one of the scouting organizations. Wear a shirt that proclaims your interest in the hobby. Be available at a special event station to answer questions.

Song: 57:17 "Sleep" by Albert Cummings from the album "Feel So Good: Albert Cummings"
