Hello all, I want to try the W8JI 'parallelogram' as described in ON4UN's low band book and W8JI's page. Dimensions 2 wires 183m long, spaced 5m, staggered 21m --what is the value of the termination
Hello all, We enjoyed the big 160m mess as well, with a relatively 'small' station.....just 600-700W into an 25 meter top-loaded vertical with 36 radials. However I set up a good reception system con
Hello all, we'll be QRV in PACC-contest saturday, february 11th, 12utc until sunday february 12th, 12utc on 160m. As main operator, I'am very interested to see how the RX-set up works, as I put a lot
Hello all, I'm searching for a low cost solid-state amplifier design in the 800-1000Watt class. I know in the past DL9AH designed something with 32x IRF710, good for 750Watt. Meanwhile there might be
Well, meanwhile I got some info. I want to build the amplifier myself so, there is no need for info about (expensive) ready made amps. Jim, thanks for referring to the G3YXM amplifier. (looks simple,
Hello all, Meanwhile I got some information about the use of Class E amplifiers with FET's on 160m, by searching the web. Unfortunatly I haven't found any complete (reliable) design yet. I know that
First off all thanks to those who send me information. Actually I found 3 possible designs: --WA1GFZ, Frank with 22x FQA11N90 in class E , unfortunatly I cannot run it as an amplfier behind a trancei
Hello all, wonder if it is possible to use #26 material cores as current transformer on 160m These are yellow/white cores used in computerpowersupplies. Putting a stack of 10-30 of them around de coa
Anyone has info about this? (schematic, component values, capacitor voltages etc) Especially looking for info about what cores are necesarry when running 1kW. Is T200-2 large enough, or maybe I even
Just to come back on the filter question. I want something that I can use behind a 160m MOSFET amplifier, which haven't much filtering in the output. The amp has to be runned in a multi-multi station
Well thanks for the comments! So, likely I have to choose a low pass filter, I guess. I suppose the advantage is that the capacitors have lower voltages on them, compaired with combinations of parall
Hello, I found some very interesting stuff about the use of a 4 square k9ay by the SP3KEY club. Unfortunatly only partial information. Is there anyone who has the emailadress from either sp3key or th
Well thanks for all those responding to this item, but.......... I was looking for detailed information about the way they feed the stuff etc. I do have info about a single k9ay system, so that's not
This weekend there is a contest in PA as well from sat 12ut until sun 12utc; we have some nice beverages up. We used to have a pair of 'staggered' beverages (2x240m) towards USA, and now have also a
Hello all, Had a nice opening into JA yesterday evening. It was the first time ever I experienced such a nice opening. We are trying to optimize our 160m station, and therefore we would like to know
Hello all, one question still open here: what about the new Ten Tec Omni VII on 160m?? How does it perform down there, and what is it like in a contest crowded band? Anyone around with in-field-exper
