Hi Mark.. sure looks to me like the issue is Northeast related. MSK144 calling frequency is 144.150 (was 144.140, but EME activity was being interfered with) and skeds commonly go to 165 and often 170. It sure would be great to find better use for frequencies below 144.100.

rr Fred, Rick, Jay, Ron, Stan, all Given the Packrats net on .150, and the fact that .175 is within the area of heavy ssb/cw use during contests (ex:W2SZ on .170), and other users (MidAtlantic+Northeast US general SSB/CW usage on .175), A frequency in the segment from 144.155 to .165 would work for FT8 and have little interference potential for SSB & CW users.Digital EME is great, and international. K1JT says 25 QSO’s can carry on similtanously without interference using 10 KHz. So, maybe they will need 45 KHz, or more during an EME contest? That’s OK too. But, it’s rare for a terrestrial station to hear anything in the 144.100-.145 segment. Digital modes will change, and get narrower and even better. A good test would be to estimate the interference potential between EME and terrestrial stations. It might be less that we think.Even if many new operators come on board, We have plenty of spectrum to operate all these modes. Do we want to ask the FCC to allow digital in the 144.000-.100 segment?Would the FT8 move get a better reception if .164 was proposed instead on .165?Tony, K8ZR, had a talk about this subject at our April Eastern VHF Conference.

It's my least preferred mode.   IMO it's a "necessary evil" to have or be left out.   If you operate 6M you know what I mean.   One thing I'd really like to change is 144.174.   Who was responsible for choosing that ?   Way too close to the SSB-CW part of the band.   Disputes already started with a long-time 144.175 SSB Net.   I'd like to start a campaign to move it to 144.165.   That's where it should have been to start with.   Who else agrees? Thoughts?   -73 Ron WZ1V  ----- Original Message -----  From: Rich Griffiths   To: newsvhf at mailman.qth.net  Date: Wed, 11 Jul 2018 22:23:28 -0400  Subject: Re: [NEWSVHF] 144.174 FT8 activity  > It's good to see all the followup posts questioning the value of FT8.  >   > Taylor and Franke made a neat accomplishment with this variation on   > their JT series.� The users can't claim the same.� There should be no   > claim to fame for making thousands of contacts when the computer is   > doing most of the contacting.  >   > If you want propagation info, WSPR and other tools are better.  >   > Personally, I hope FT8 use is just a fad that will slowly fade away and   > the users will find other tools with more communications value.  >   > ..
