Topband: 160m monoband amp (was strange propagation)

[Louis Parascondola]

Thanks Mike, I'm not going anywhere.  I hope that Tom reconsiders his leaving.  If you look at the time and effort he spent on his website which he always updates and adds to, and the efforts he puts forth on the various reflectors you have to say it is nothing less than admirable.  A handful of people do such things and many of them are on here also.  So I agree, this is the place to be.  I've know about this reflector for years but never bothered with it since my interest in 160 was nil.  Recently I made a decision to give it a crack and boy do I see it is a whole lot different than working even 80 meters and above. Lou W1QJ

Hi Lou,


Of all the sources of unique help and info about 160 meters, IMO this reflector is the best one.
I suppose you've found the searchable archives, which I've found invaluable many times:

lists.contesting.com/archives//html/Topband/

lists.contesting.com/archives//cgi-bin/namazu.cgi?idxname=Topband

There are other sources, notably ON4UN's Low Band DXing, published by the ARRL. Everyone with an interest in 160m should own a copy.


There are a number of other informative web sites out there, too. I have some of them listed and linked to from www.w0btu.com (not all on one page, sorry). And there's a page there about Beverage antennas there that you might find useful.



Maybe you would let me pick your brain sometime about my swamped-grid dual-833C legal limit amp. It works fine on 160 and 80, but it needs neutralizing if it's going to be stable on 40 (and work at all on 20). I have a plan to neutralize it using a tertiary winding on the input transformer, but I foresee a lot of trial and error. But I don't have time to work on that right now.

I wasn't even sure if two of those triodes in parallel would even work, so I didn't spend a lot of time making it look pretty.

Stick around, Lou. Believe it or not, this is usually a friendly forum!

I came to the group to try to pick up pointers on improving my 160 meter experience.  In the short two weeks I have been here I have so much information to digest.  Especially with receiving antennas,
