BRIAN JUSTIN AND CREW MAKE NEW 145GHz WORLD RECORD

On Jan 1st, 2001 at 23:22z, W2SZ/4 worked WA4RTS/4 on 145GHz over a distance of 61Km.

W2SZ/4 was operated by Brian Justin WA1ZMS from FM07fm (37-31-4N 79-30-40W).

WA4RTS/4 G.P. (GEEP) Howell was located in FM08ia (38-2-57N 79-18-37W)

The distance calculated based on actual lat/long is 61.6Km.

The distance calculated based on centers of the 6 digit grids is 59.7Km.

The weather at the time of the QSO was 15F an 60% RH at the FM07fm end.

No weather data was taken for the FM08ia end, but the temp was around 25F.

The atmospheric losses were calculated to be around .27dB/Km.

Equipment used was the same gear that set the former North American record on Nov. 6th, 2000.

Some changes to the feed system of one dish gave the extra signal margin needed to extend the record to the 61Km mark.

The addition of Rubidium standards to each station also helped by practically eliminating any frequency error.

As with the last North American record, we've reached the 0dB S/N limit of one station, so further DX will require much work on the stations themselves.

I left my audio recording gear at home, so no wave files are available.

Pete, W4WWQ and John, N4QWF helped during this rather cold rover effort and photos taken by Pete of a test QSO earlier in the day as well as photos from FM07fm
