Re: Topband: Top Band and JT65

Mark, What you are saying is, that by using the K1JT shorthand messages, i e single carriers representing a report, confirmation "RRR" and "73" we are seeing a wonderful advancement in communication technology. JT shorthand messages are nothing but a carrier at a certain frequency offset.

Re: Topband: Top Band and JT65

In the context of this discussion I think RTTY is an "in between" mode. Decoding is done with a computer (or in the radio if you have a K3) but I've never seen a decode on a signal that I couldn't hear or see on the spectrum display. As a non-contest DX chaser, I find that it often takes

Hi Rick, That's a very good question indeed! If we would go back through the Topband archives, I think that a major factor in this is the CW skill of the operator. Some are not so good (and we should not berate them for their lack of ability!); and those fellows will benefit more from the

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

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
