BN-86 is a transformer and BN-4000 is a choke. Both a bad investment in my experience. 73 Bert, VE3NR I get it now - transformer vs. transmission mode. Thanks Hector ! Matt From: Hector Garcia,XE2K [

Cushcraft A3 and A4S are cheap designs with inferior materials, especially boom-to-element clamps, which are basically just a cheap muffler clamp. One of my friends A4S lost the reflector as it wiggl
Hi Bob, Drill 2 new holes in the flange of the thrust bearing if there is space available. Problem solved! ;-) 73 Bert, VE3NR --Original Message-- From: TowerTalk [mailto:towertalk-bounces@contesting
I just checked the design of the TB2 and there is no space to drill another couple of holes. Sorry! Bert, VE3NR --Original Message-- From: TowerTalk [mailto:towertalk-bounces@contesting.com] On Behal
Use crimp UHF and solder the center pin. Much better! Bert VE3NR Good stuff Roger! One thing you left out. You mention the gob (or glob) of solder on the center pin but soldering the shield through t
I learned long time ago that using pop rivets, blind or not, don't make for a good electrical connection. For all antennas, using aluminum tubing, I've used self tapping screws for the last 30 yrs an

Jim, While I agree with most of you're writing I think you'll be hard pressed to get a solid 9 square inches of surface contact in your 1 inch tube with 3 inches of overlap. Maybe if you put in a lot
Very true! Forgot about the capacitance. Bert VE3NR to the a clamp Don't forget the capacitance. 9 square inches separated by 1 mil is about 2000 pF at 14 MHz, that's an impedance of about 5 ohms. Ev
As I was reading the post I was wondering if you could use ferrites of different mix in the same choke/balun? Would that work or not? I've read Jim's/K9YC excellent paper on chokes and baluns, but I
Hi Danny, Rack and pinion is mostly for linear motion. I believe a worm gear with direct drive or a chain drive would be a better choice. Using a worm gear you have the breaking function built in. Go
Hi guys, I was surprised when I read Roger's statement about US unemployment but here is the proof http://www.wethepeopleoftheus.org/true-us-unemployment-rate/ I guess it depends how you look at it b
Joe is absolutely right. I've been a business broker in Canada for a couple of decades and have some experience. The first and most important question to ask yourself considering investing in an ongo
...and this device (choke) would give you over 30 dB attenuation from 1 to 30 MHz!! I'm definetely missing something!! How can this kind of advertising be allowed? I'm no expert but I've made a few c
Hi guys, You're still ahead of the game. Here in Canada most provinces charge 11-15%. We're lucky we're not living in Sweden, my country of origin, where they charge 25% on almost all sales!! Bert, V
Hi guys, Does anyone have any experience with ferrite material #28 from Laird? A friend of mine tells me it's similar to material #43. Comments appreciated. 73 Bert, VE3NR ___________________________
Hi Rick, Thanks for your comments. I'm was planning to use the ferrite toroids to make common-mode chokes for HF. I found 2.4"x1.4"x .5" toroids on Digikey, Laird #28 for around USD 4.00 in quantitie
Hi guys, A friend of mine told me the other day he's putting up a doublet for 80/40M feeding it with a ladder line. He also wants to use the doublet as a T-antenna on 160. The doublet will be put up
