Hi Bob, It wasn't oxidized copper anyone was worried about, as all component leads had coatings well before HSD was ever implemented. The real problem was "what" they were coated with! It varied from

Finally, according to the SPG experts, I will need to spend $300 or more to get all of the cables and wires coming into the house tied to one ground panel. The electrical entrance panel is at least 4
I noted that Keith had said in an earlier thread that he used a solder station set at 650F. I have a TC201 (42 watt) with a 700F short conical tip and it takes a long time to solder the shell. I usua
A solder station doesn't provide sufficient thermal mass to transfer heat to a PL-259 connector body. You obviously have not used a Weller WESD51 or EC1002. After you "drain" all of the heat from yo
Tower Talkians, Anyone have a good source for quality RG-11? I need to install a moderately long run for cable tv. use RG216/U as a minimum (double shielded RG11/U), but frankly RG6 quad shielded, sa
Loss...not much difference. RG6 Quad is manufactured expressly for the cable and satellite TV markets, has a foam dielectric and is 100% shielded and has better characteristics for the application th
I'm amazed they use RG11. When you look at it (if you get a chance), I'll bet you find it really is not RG11, but a special CATV version of RG11 that has a foam dielectric and multiple shields. Nobod
Hi Jim, Good rant. I have mil-spec (MIL-C-17/6B imprinted) RG11/U on spools in my garage. I'm trying to remember the mill, probably Carol or Times. It's not very new, I've had it several years, proba

That's not entirely true. Ever try to make a vhf or uhf duplexer on a two way radio system work with only single shield interconnects on the cavities? Especially with a close spaced system. You will
About 30 years ago, I worked for an MATV contractor who had lots of installations in high rise buildings on Chicago's Lake Shore Drive, in the shadow of VHF and UHF transmitters on Hancock and Sears
Jack, I had a 3K Premier for many years (I owned the first prototype of this amp, actually, and it was designed just for me as the very first amateur amp Henry ever built that covered 160 meters, in

Re Telrex 40m yagis: You know which model KS8S had, Mike? Performance-wise the 3 el on 29' boom model was marginal while the 3 el on 46' boom played very, very well. I used them both, at various stat
Sounds like my Gotham vertical. It does exactly the same thing. Even when I have it pointed the wrong direction, it is louder than the 6 element big stix. Congo! I remember those ads.....-WB2WIK/6 __
Golly, Weren't those ads fun? Gotham could do anything with nothing at all (ha-ha). One lives and learns (gosh but we are showing our age and hopefully, maturity). one watt and a single crystal on 70
The pattern was just a little (ahem) skewed in gain across the aperture, but the important thing was, we worked Jupiter! (Well, not really, but we heard it) rig...-WB2WIK/6 __________________________
Mark, these things are useful for miniscule parts having no thermal mass, like soldering a clasp on a piece of gold jewelry (if it's a small piece). Solder a PL-259 with it? Hahahahahahhahahahahahahh
