Gerard - Wow! .50 cents!?  I have only found Mullard and Brimar 12AU7 going for $35 Plus... I have even seen some folks asking upwards of $100.... if your Dad knows of a reliable source at those prices - sign me up!

Called my dad and he said that is a very common type of tube, and that $34.95 price tag on the link Rowland shared was super crazy over priced. Good used ones can be found for .50 cents . But if someone can’t find that AU for under $35 let me know and he said he’ll dig some out and mail them to me. He’s in New Jersey, so it won’t happen overnight.

Let me call my dad, he’s an old school tv, radio electronics repairman. I know he’s got a lot of tubes, just don’t know which.

Hey Folks,

At the online SnoVARC meeting last week we discussed the possibility of running a Technician level online class.  We have 20 students who jumped at the chance.

Next step is to find folks like you to be mentors.  Then on some scheduled basis, mentors will be available to answer questions, provide insight, and understanding.  Each student will be asked to sign up and use hamtestonline.com.

I need mentors who will help with this.  Please let me know if you are interested, and how you could help.

Tests will be administered after the quarantine.

Urgent message for Badged CDCCC Volunteers:


An opportunity has come up for Carnation-Duvall Citizen Corps volunteers to assist in a local response due to the COVID-19 pandemic. The Cities of Duvall and Carnation are opening a Hot Line to support citizens who fall under the vulnerable populations category and might need assistance with certain tasks, such as grocery shopping, picking up prescriptions, etc. The Cities will take the calls and CDCCC Volunteers will perform the tasks, which are expected to take place during daytime hours. This is NOT an emergency response. YOU MUST BE A CDCCC VOLUNTEER WITH A KING COUNTY TEMPORARY WORKER BADGE TO HELP WITH THIS RESPONSE. If you want to assist with this response please contact Kathy Brasch at info@... or call 425-941-9295 and you will receive further instructions.

Rowland asked if adding a reflector below his 80m OCFD would improve NVIS performance on 80m.

 

Error! Filename not specified.

 

A bit more than a 2dBi improvement at 90 degrees.  That’s with the reflector length optimized for gain.  The modeled reflector height was .1m AGL.

 

The downside is that it messes up SWR somewhat.  I didn’t snap a comparison though, there are just too many installation variables to make the results meaningful.

Subject: [SnoVARC] Rowlands reflector question

 

Rowland asked if adding a reflector below his 80m OCFD would improve NVIS performance on 80m.

 

Error! Filename not specified.

 

A bit more than a 2dBi improvement at 90 degrees.  That’s with the reflector length optimized for gain.  The modeled reflector height was .1m AGL.

 

The downside is that it messes up SWR somewhat.  I didn’t snap a comparison though, there are just too many installation variables to make the results meaningful.
