Back then I’m guessing it probably was CW, but know that it has been done since then on SSB with S9 signals. Far as 1KW, LOL, have you seen how much it costs to get any kind of decent power (aka > 100W) on 5GHz? ;-)

(Reference: http://www.arrl.org/distance-records) I suppose it will only be a matter of time before some radio amateurs decide to get some broadband equipment on either end of this path and show Cambium how puny a 245km link really is. ;-) …Ron NN5DX From: Af [mailto:af-boun...@afmug.com] On Behalf Of Adam Moffett Sent: Monday, August 10, 2015 9:15 AM To: af@afmug.com Subject: Re: [AFMUG] PTP 650 Sets New Wireless Broadband Link Record of 245km burrrrrrn On 8/10/2015 9:59 AM, Andreas Wiatowski wrote: Maybe it only has the Lite license. ;.> Cheers, ______________________________ Andreas Wiatowski | CEO Silo Wireless Inc.

Ran the link at 5, 30 and 45 MHz channels and had receive signals of approximately -76 dBm even while battling some pretty heavy winds. We were running a high-def video link and a VoIP server over the channel. Consistently stayed above 30 Mbps which is what we had designed the link for. The link was established with both PTP 650 and PTP 700. The link came up fast and we were testing out the applications after less than an hour on site. LINKPlanner does take the curvature of the earth (and altitude) into consideration. Join the Conversation Cambium Networks Community Forum <http://community.cambiumnetworks.com/>
