1. Topband: Top Band and JT65 (score: 1)

I am hoping more DX stations will take advantage of the JT65 mode on 1838 next season. I have been using it on 20M recently and am amazed at its weak signal performance. This mode should enhance the

Why not JT9? It has a 2 dB improvement in S/N ratio on 160, while using only 1/10 of the bandwidth. I cannot understand why JT9 is used so little on 160 thru 20. JT65 is a VHF mode. physics.princeton

This may sound strange, but my opinion is that hams like the musical tones of JT65. I cannot understand why JT9 is used so little on 160 thru 20. JT65 is a VHF mode. physics.princeton.edu/pulsar/K1JT

Maybe some do. But I usually turn the speakers off when operating digital modes. That extra 2 dB over JT65 --as well as freeing up large portions of the band-- ought to matter to more hams. 73, Mike

I find the better ability for JT65 to decode co-channel signals with its two pass decoding makes up for any 2dB improvement in decoding JT9. I also find a single static crash can take out JT9 decodes

That's interesting. Thank you for sharing that with us. What software are you using, Brian? Joe Taylor's, or some other? I'm guessing you're only using the wide SSB filter. In any case, I'll have to

Wrong. Both in SSB and AM cases the operator's skills and abilities are involved. Even more of those are needed on CW. On those JT modes an operator is just a computer accessory. -- 73, Victor Goncha
