201. [TowerTalk] another "geo888" problem? (score: 1)
Author: "Jim Jarvis" <jimjarvis@comcast.net>
Date: Thu, 3 Mar 2005 07:41:07 -0500
Let's not all pile on this one...the list moderator will see one post. However, has anyone else noticed that GEO888@cs.com has NOT returned undeliverable for quite a while? Several weeks, in fact. It

I take it back. Previous msg about Geo888 was incorrect. (he determined by having posted said msg.) Guess I've been too efficient with the delete key. Was looking at an admin. mailbox address in the

Folks, Before we get too carried away bashing Nello, or anyone else....I acquired some new rohn 45g 4 or 5 years ago... and found the legs wouldn't align. It's clear that some of the mfg. jigs Rohn w

Some of you may recall my posts on this topic a few years back, when I was considering driving two LPDA's with separate amps. The notion of controlling phasing at low levels in intriguing. But in ord

If I recall the story on GKK, which ran in either QST or CQ, a few years back, not only was his philosophy "be there when they're there"...it extended to "they'll always be on 20". As a result his an

Hi Tom & Peter.... Yes, I noticed the aurora on northern latitude stations, even as far south as Hamburg. One DL and I noticed the AU, and I mentioned it to him..and asked his qth. It's hard to notic

I commented on Peter Sundstrand and Tom Rauch's comments off-reflector. Brief summary: I'm aware of the aurora, although I didn't mention it. The tendency is NOT to notice things that AREN'T present.

I think you're under-rating the SteppIR, Peter. As I said in my private mail, I had a 3 el in Vermont and was quite pleased with it. I'd STILL have it, if it weren't for relocation...and another one

Turns out that sign companies have boom trucks to 85', capable of lifting a man plus 300 lbs payload. Prices run lower than crane companies, for whom a ham tower is a very light challenge. Worth expl

Author: "Jim Jarvis" <jimjarvis@comcast.net>

I think it would be more valid to compare the 3 el SteppIR price ($1200) against the C3 ($700). The price of convenience and flexibility is thus $500. Not that I'm trying to talk you into anything. I

Tony's right...I forgot to add in the price of a warc antenna, coax and/or antenna switch. Probably brings it to a wash. Which makes the steppIR convenience and performance almost free. Jim Jarvis 41
