Re: Topband: Receive loop observations

Hi Herb (KV4FZ), You said "but the 50 turns is going to be a chore" The only problem I find with winding a core with many turns is keeping track of the number of turns. What I do to solve the counting problem is that I take a zoomed in picture showing all the windings (using my smart phone

Re: Topband: Receive loop observations

I couldn't resist..K9YC says"The BEST way to buy ferrite parts is...buy in quantity from industrial distributors" Well, first off, I don't need quantity - I need one or two ferrite cores.so, I guess I'm "out of luck," eh? Let's see --- to test K9YC's

Topband: Preampm for 160 meter receive loop

OK - did a little listening yesterday evening and this A.M. on 160 with my loop and found band noise way down, relative to my transmitting antenna (an Inverted U). So, I'd like to add a pre-amp at the base of the loop BUT when I google 160 meter preamp for sale (or 160 meter preamp kit) the

Re: Topband: Receive loop observations

If you're on the air and have neighbors, you've got RX noise, and most of it comes from noisy electronics. SO -- you need ferrite cores to suppress that noise. You also need ferrite cores to kill common mode current on antennas. If you can buy cores that do both, you can buy in quantity.

Re: Topband: Receive loop observations

You make my case, Cecil...my "requirements" are - I need two - and not in the position of buying beaucoup and hoping I can sell, at cost, to others I forgot the minimum "reqmt" of Newark - thanks for the reminder -- makes my position - small companies like W8DIZ' are more relevant when

Topband: MA-160V

I just picked up a used one. Any tips? Internet comes up a little bit dry. Anyone have any first hand knowledge? My intention is to use it sometimes @ home and sometimes "afield" with only a few radials (possibly raised if possible) 73 de Mike VE9AA Mike, Coreen & Corey Keswick

James, Here is a link to a low cost preamp on ebay. I have purchased one and it works as advertised. Maybe this will do what you desire to accomplish. http://www.ebay.com/itm/J310-push-pull-HF-pre-amp-KIT-BUILT-TESTED-/151745349257 ~73 Don KD8NNU 2014 3905CC Top Gun :-) -.- -.. ---.. -.

Re: Topband: Preampm for 160 meter receive loop

I've made and used several W7IUV Preamps over the years and worked well.  There should be schematics on line still but I do have them if anyone is interested.   Regards, Jim/k2hn _ Topband Reflector Archives - http://www.contesting.com/_topband
