What are you experts using for strain relief on the coax? I cant see the PL-259 taking all the tension of a very long length of RG-8 (plus a nice fat K9YC choke). I always think of Kellem grips in si
An affordable solution is the VNWA. Its only a 2-port VNA, but its application includes calculations for 3-port measurements. As I recall, DG8SAQ included that specifically for baluns. Users say it
Surf over to buyheatshrink.com. I get all my adhesive-lined tubing there. They have 4:1 as well as 3:1. The thick-walled stuff is like a rock. I wont use anything else on connectors. http://buyheatsh

Because the heavier-walled adhesive-lined tubing cannot be bent or coiled without some damage, and they supply it in 4-foot lengths. They ship it in a rigid cardboard tube. BTW, I only use it on the
An effective clear anti-corrosion coating for aluminum is class 3 chemfilm, a.k.a. Alodine 1500, which are all names for a particular chromate conversion coating. You more often see class 1, which is

Heres a re-post of my detailed price comparison for type 31 toroids and clamp-ons from last June. KF7P put on a special sale back then and I ended up buying a bunch from him Maybe hes up for a repeat
Does anyone offer a coax stripping tool to prepare Buryflex for PL-259 crimp connectors? The DX Engineering coaxial cable stripping tool does a nice job for solder connectors. Looking for something l
I'm still searching for the perfect QTH, but so far I've had wonderful experiences in contacting hams in various towns. If I don't already know a ham in that area, I search in QRZ by city, then pick
The cell tower on the property at N6RO has a battery charger that they confirmed is a switcher. Generates a nice bunch of hash on 80 and 160. They refuse to fix it. Gary NA6O ________________________
