[BVARC] Power Pole to Power Pole and Banana - Banana jumpers needed for the Equipment Check Table

[John Chauvin via BVARC]

Can someone lend BVARC 3 or 4 sets of Power Pole to Power Pole and Banana to 
Banaana jumpers for use at the equipment check table?  All ratings are welcome; 
lengths of 3-6' preferred, but I'm not picky.  Contact me as cited below.
If you are interested in helping at the Equipment Check Table, you can sign up 
at: 2024 GHHFEqCkTable  or you can contact me by replying directly to me 
(please do not "reply to all") at k5...@yahoo.com

Hello all,


Here's another reminder that we will be going to Brazos Bend State Park this  Sunday February 25th doing Parks On
 The AIr (POTA). If you're interested in participating or just hanging out with us, we're asking folks to come by between 10am and 5pm. If you'd like to help set up you are welcome to come
 a little early. We will be located at the far end of the Elm Lake part of the park. Call us on 146.520 MHz simplex if you would like to reach out to us while in the park for

One more reminder: There will be a pre-POTA net

Josh,
Good afternoon.  Welcome!  It was a fun event to be sure.  I kept getting this 
fellow on CW giving his callsign as TI5JON and I stubbornly replying to him: 
“KI5JON ?”.  It turned out that he was indeed a TI station in Costa Rica and 
not a KI station from the US!  

Don’t be a stranger and hope to see you guys in more Ham radio activities!

[BVARC] Volunteers Needed - Greater Houston HamFest

[Mike Hardwick via BVARC]

Volunteers Needed – Greater Houston HamFest

 

Needing volunteers for two critical areas.

 

1.   Table Set-up and Tear-down

 

A scheduling conflict has recently arisen with the group whoset up the tables 
and the podium at the Greater Houston HamFest.  Three to four people are needed 
to do thiswith it taking 2 to 3 hours for setup and about 2 hours to teardown.  
The critical time is the setup.  You are not necessarily being asked to 
helpwith both setup and teardown.

 

Setup tentatively will take place between about 10 and 1 onthis coming 
Thursday, February 29 (the day before the actual Hamfest starts).  These 3 
hours can be varied if tooinconvenient.  Someone will be there mostof the day 
tending to this and other pre-hamfest work; In addition to the 2 – 3hours for 
table setup, we need other volunteers for an hour or two at any timethroughout 
that day (Thursday).  Teardownstarts immediately after the Hamfest ends at 3PM, 
Saturday, March 2.  If you can help, please contact Mike Hardwick,N5VCX at 
n5...@att.net or at 713-826-6917. 

 

2.  Loading and Unloading

 

To help both vendors and support for the hamfest, volunteersare needed to help 
load and unload vehicles. Some of the areas needed aresupport for Robert 
Polinski with the PA system, HRO unloading their truck, HAMWEARSunloading their 
vehicle and several other vendors. The time on this starts onThursday at 9 am 
and continues off and on throughout the hamfest. 

 

If you can spare 15 to 30 minutes Thursday, Friday or Saturdayin the morning or 
afternoon, it will really be beneficial. If you can help, pleasecontact Mike 
Hardwick, N5VCX at n5vcx@att.netor at 713-826-6917.

It would seem to me the fast rise time of the lightning pulse makes it similar 
to any RF good practice concernsthe safety ground path should have low 
inductive reactance, not just low resistance.   It also seems to me that skin 
effect resistance of braided strap may be lower than the skin effect resistance 
of  stranded large gauge wire because of the increased copper surface area of 
braid (keeping other things the same).  But all the weaving of the tiny braided 
little strands may present an increase of the  inductive effect, unless the 
strands are not tarnished and act like a solid band -- so that may be why, 
these days, you see a preference for copper straps that are not braided.  So I 
am not necessarily pushing a conclusion on what is best, but rather "thinking 
out loud" on why some choices may be better than others.

The type of wire is not important in bonding applications. The object of 
bonding is to prevent potential voltages from 2 different grounds. In the event 
of a lightning strike, you want all grounding systems to be at the same 
potential.  This relates to safety & equipment protection, not RF grounding. 
Example, if your electrical service ground has a resistance of 3 ohms (NEC 
requires it to be 4 ohms or less) and your ham station ground is 1 ohm, if 
lightning strikes the power lines on the next block, the surge coming in the 
power  line to your home will be seeking your ground rod at your home. This 
surge will not be the full current of the strike, as ohms law is in effect, 
resistance of the ckt limits the current. If the strike sees your house ground 
at 3 ohms, but the ham ground is 1 ohm, It will take whatever path it needs to 
that lower resistance ground, that means thru your radio or any other equipment 
that has both a electrical ground (3 wire cord) & a ham station  ground 
(antenna system) The bonding between these 2 grounds makes the surge see the 
low resistance of the combined grounds and greatly lowers the chance it will 
take a path thru your equipment. Robert

Use braided copper for bonding but minimum AWG6 wire for external grounding and 
lightning protection.

Every single ground system in the N0AX book suggests wire not braid.

 Braid is fine for indoor use where copper strap is not practical.  Use of 
braid outdoors is not a good choice because oxidation will likely result in 
unwanted impedance.

inductive reactance, not just low resistance.   It also seems to me that skin 
effect resistance of braided strap may be lower than the skin effect resistance 
of  stranded large gauge wire because of the increased copper surface area of 
braid (keeping other things the same).  But all the weaving of the tiny braided 
little strands may present an increase of the  inductive effect, unless the 
strands are not tarnished and act like a solid band -- so that may be why, 
these days, you see a preference for copper straps that are not braided.  So I 
am not necessarily pushing a conclusion on what is best, but rather "thinking 
out loud" on why some choices may be better than others.

Totally agree and it’s vital to measure the grounding resistance, both my 
positions (station and electrical service are linked but 300ft apart) are sub 1 
ohm which is well below code. All my bonding inside in the shack leads to a 
common grounding copper bus bar with braided copper cables to each bit of 
equipment. You can only do so much but every little helps.

The type of wire is not important in bonding applications. The object of 
bonding is to prevent potential voltages from 2 different grounds. In the event 
of a lightning strike, you want all grounding systems to be at the same 
potential.  This relates to safety & equipment protection, not RF grounding. 
Example, if your electrical service ground has a resistance of 3 ohms (NEC 
requires it to be 4 ohms or less) and your ham station ground is 1 ohm, if 
lightning strikes the power lines on the next block, the surge coming in the 
power  line to your home will be seeking your ground rod at your home. This 
surge will not be the full current of the strike, as ohms law is in effect, 
resistance of the ckt limits the current. If the strike sees your house ground 
at 3 ohms, but the ham ground is 1 ohm, It will take whatever path it needs to 
that lower resistance ground, that means thru your radio or any other equipment 
that has both a electrical ground (3 wire cord) & a ham station  ground 
(antenna system) The bonding between these 2 grounds makes the surge see the 
low resistance of the combined grounds and greatly lowers the chance it will 
take a path thru your equipment. Robert

Use braided copper for bonding but minimum AWG6 wire for external grounding and 
lightning protection.

Every single ground system in the N0AX book suggests wire not braid. 

 

The two are totally different animals

Make sure that ether you or your electrician, run a #6 wire from the electrical 
ground to any ground rods you install at your ham system. They need to be 
bonded together. Robert

I'm not answering what you asked, but for a new 2nd story install  I will 
suggest you put a good deep copper ground rod in the ground directly
