Re: Topband: Loop query

Jake: If it's for Field Day only, then forget about the expensive balun. For a single-band loop, my suggestion would be to use a 1/4WL piece of 72 Ohm coax (take VF into consideration when calculating 1/4 WL figure) as an impedance transformer between the nominal 100 Ohms of the loop

Re: Topband: Top Band and JT65

Promised myself I'd stay out of this, but it's getting ridiculousComments like "I worked 20 new ones on 160, and I never heard any of them!". Wow! That's amazing...I personally can't find any satisfaction in claiming a contact I never heard. I never have...Yes, the digi modes allow easier

Topband: Fwd: Re: Loop query

Hi Jake, It is not the best antenna for DX ,, but a good antenna for Field Day. The rather high angle pattern should net you many QSO's. With the match box an acceptable VSWR for the transceiver should be possible. Good luck & have fun. 73 Bruce-k1fz

Re: Topband: Loop query

The answer depends on a few things. 1. How high this this loop going to be? 2. Is it going to be parallel with the earth (horizontal) or vertical? 3. Do you want to work just the surrounding states, all of North America, DX, or all of the above? A horizontal loop on 160m is an NVIS antenna,

Re: Topband: Loop query

How do Top Banders, I've got a "theory" question for the collective group. Think Field Day. Full wave loop on 75/80 meters. Coax fed with a 2:1 balun. (I know, use ladder line and a Match Box). Is it usable if you use ladder line down to near ground level into the balun, and coax from

Re: Topband: Stone age arguments

Roger, I pretty much agree with what you're saying. However, some of us here (me included) are NOT arguing. Rather, we're trying to learn something. :-) 73, Mike www.w0btu.com On Sat, May 20, 2017 at 3:09 PM, Roger Cooke wrote: > > I have been following this argument with

Topband: Stone age arguments

Hi. I have been following this argument with some amusement. Only because it can relate to just about any situation that we can think of. Example 1 I got a teleprinter in 1959 and put it on the air. I was told in no uncertain terms that the awful jingle-bell QRM was not amateur radio

Re: Topband: Top Band and JT65

Rick, The technical explanation takes into account a number of conditions. The details are all available on K1JT's website. If memory serves, it uses 2.5kHz BW in the calculations. CW will have different readings depending on the BW used. All I can say, as a user of the mode, is that in

Re: Topband: Top Band and JT65

Mike, I'm most interested in hearing more about your conversation with K1JT about JT9. I've been away from the WSJTGroup for some time, and may have missed any new info about the mode. In theory, JT9 should be the chosen LF mode. A couple of dBs more sensitve, and about 10% the BW of JT65.

Re: Topband: Top Band and JT65

I've never operated JT65, so maybe some of you experts can answer a beginner's question. Searching on line, it is difficult to get a definitive answer to how much advantage it has over CW, but the number seems to be around 10 dB. Maybe not even that much if the receiving station is using an SDR

Re: Topband: Top Band and JT65

I haven't even listened for anything digital in several years. But I need to share some things soon --that K1JT himself told me via email-- concerning JT65 vs JT9 on 160. To make a long story short, I'm no longer 'preaching' against using JT65 in favor of JT9, as I have been in the past. More

Re: Topband: To JT or not to JT

This sounds like a question that will always be around. To me the great thing about all of this is the increase in activity on a band that does have some rough times with propagation. I know that for myself, using the JT modes along with my very inefficient antenna and 'low' power, has

Re: Topband: To JT or not to JT

Right! When we see some of issues that are popping up now, such as remotes being used outside ones entity but claimed as inside, to argue about which mode is worthy or not, is misguided. In addition, is not like 160 is a crowded band. :^) 73 de Vince, VA3VF On 2017-05-20 1:25 PM, rick

Topband: To JT or not to JT

There is no question. get them anyway you can mixed. If you want an all CW, SSB or Digital, go for it but don't belittle guys that don't have 500 ft. beverages in 6 directions and full size 4 squares for transmitting. I have 91 countries on topband with an S-7/8 noise level and if it

Re: Topband: Top Band and JT65

It seems the the something worth working for would be worth striving for. Having WAS on 160 Qrp posted on the wall always reminds me of the effort of operating and the time spent learning about antennas that actually work over the long haul distances required. Instead of taking many minutes
