Re: Topband: FT8 discussion

I know this has been “Discussed Out,” but I just want to ask why the window is in the 1840 area instead of the 1990 area? They are asking for QRM at 1840. It will be a losing battle during contests. Just sayin’ Chuck W5PR Sent from Mail for Windows 10 _ Topband Reflector

Topband: FT8 qrm & Bandplanning History on 160m

Hi Jeff Agree with most of your comments . . . However - if there was a 160m CW sub-band, it might be a RULE in the USA . . . but it wouldn't apply elsewhere . . . So what would be the point?! I think 160m works pretty well as it is. (and compared to all the other bands, it's still the most

Re: Topband: FT8 and digital QRM

160 is the only HF band where all HF modes (except CW) have no restrictions. The FT8 guys will really enjoy the CQ WW 160 SSB contest! At least 160 isn't all that useful to the 2.8 kHz wide Sailmail guys -- they really use the full 2.8 kHz. The band segmants are pretty consistent on all the bands.

Re: Topband: FT8 qrm - 3khz wideband digital

My two cents is - at least with FT8 so far 99.99 percent of the folks stay in the 2 - 3 khz segment . I am amazed I see virtually nothing about the proliferation of 3 khz wideband digital two way hash on all HF bands . For instance last night on the ZA1WW on 3536 , it covered both the ZA and

Re: Topband: FT8 discussion

Well said. Just a few weeks ago, someone made the point that we should be thankful that there is activity up there. The gist of it was that during the year, much of the time the only activity on 160m is digital. "Use it or lose it" was his point. I do not wish to discuss this. 73, Mike
