Not that I have ever noticed with 242. A small bottle lasts me for years, and it always seems the same. -- 73 from Ian GM3SEK 'In Practice' columnist for RadCom (RSGB) http://www.ifwtech.co.uk/g3sek
Thanks, Charlie - that's excellent information. As regards curing time, we come back to Jim's warning that there's more than one "it". According to the data sheet, 242 will cure on stainless or passi
I don't think there's any evidence for deterioration in exposed environments - quite the opposite. The Loctite seals and protects *everything* inside the thread gap, not only the two metal surfaces b
Whichever method you use, always add your own local knowledge about the first few hundred feet from the tower. The closer the reflection point is to the antenna, the more fine detail is needed. A typ
It is probably due to the limited directivity of the Wheatstone bridge circuit. If the bridge is not perfectly balanced, there will be some small "leakage" of the forward signal into the detector por
In Peter's household, even the cat can use a slide rule (wish I'd had the camera handy when it did that). -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ________________________________________
Worse yet, one of our locals screwed a PL259 into the N socket on his new rig! (Ohlordyme, the shells *do* use the same thread, don't they? Makes a quiet exit to upgrade the club's teaching materials

We beat 'grades of Loctite' to death in August of this year. The archive is at http://tinyurl.com/yoxjdg I'm not a high-volume user, but have never had a single failure with Loctite 242... and that d
As well as locking the threads, Loctite is designed to seal them against penetration by water and moist air, so it's one of the best things you can possibly do to prevent corrosion. Nyloc nuts. That
Please can we confirm what is meant by 'flooded' heat shrink tubing? Are we talking about tubing that is coated internally with fairly normal type of hot-melt glue... or can it also be something else
Thanks for the confirmation, Roger. Heat shrink tubing lined with hot melt glue is readily available in Europe. I use it a lot for waterproofing, and also to increase the pull strength on small conne
Have you downloaded the latest HFTA instructions from the ARRL site? http://www.arrl.org/notes/9876/HFTA.pdf (updated Sep 10th, 2007) -- 73 from Ian GM3SEK 'In Practice' columnist for RadCom (RSGB) h

Tin/lead solder will continue to be available. Assuming the US regulations follow those already existing in Europe, tin/lead solder will be legal to sell, legal to buy, and legal for us to use. The E
Welcome to the Wet Coast of Europe, Barry. The main cable entry here is in a similar exposed situation. First of all, don't use a large diameter unless you absolutely have to... and it seems like you
With one more capacitor, it probably wouldn't be difficult to make the same network match on 40m as well, without switching. As a starting-point, try doubling all the L and C values in this 40/20m de
I was assuming he might follow your suggestion to do that. On 80m it would be a top-loaded T, to be fed at low impedance against a good ground. On 40m it would be what G3VA describes as an "inverted

There's an interesting demo program from the British consultancy firm Plextek, which shows how a 'four-square' configuration can be adjusted to produce two simultaneous nulls while still maximizing t
