These feeds will be down tomorrow as I move them to a new (higher elevation) site close to KBED.  This site will run a directional antenna to start and then a discone will be added in about a week or so later and combined with the beam.

The feeds may be reorganized a bit as well.  Will post more tomorrow.

The following feeds are now being run from a location closer to Boston, in the Rt. 495 area northwest of Boston.  This is about 15-20 miles closer to Boston and Bedford, MA. Previously these feeds ran from my house.


I installed a Grove Scanner Beam (pointed southwest toward CT) that I had lying around up on an antenna tower at about the 100 foot level.  This is above all trees and the view from the top of the tower is pretty amazing.  It is a clear shot in all directions.  The location is about 700 feet above sea level.

The following improvements were noted:

1) On the KBED feed, reception of Bedford Tower (KBED) is improved and we can now hear most aircraft on the ground at Bedford.  Bedford Clearance Delivery and Ground are included in the feed now.  Both Lawrence Tower (KLWM) and Beverly Tower (KBVY) are audible.  Sometimes Beverly Tower is right on the edge of the squelch but this should improve a little as the leaves fall off the trees.  Overall, reception is greatly enhanced.

2) On the KORH feed, reception of Boston Center (GDM 36 123.75 and CON 37 134.70 sectors) is greatly enhanced, as is Bradley Approach 119.0 and Worcester Tower 120.5.  On the UNICOM frequencies (122.7, 122.8, 122.9), reception is very good, and we can hear aircraft from pretty far away.  Still evaluating that - and may move that traffic off to another feed with perhaps UNICOM and Flight Service and Flight Watch + Guard only.

3) Boston Center (Misc)

I'll list all the frequencies being scanned when I retrieve the scribbled piece of paper, but this feed covers essentially all the Boston Center low and high altitude frequencies except the ones listed under the zbw_dj feed.  All of them except 123.75 and 134.7 have the scanner DELAY set to off.  This is a primarily aircraft-only feed which is designed to have a wide sampling of what's going on on the Center frequencies.  Occasionally the 124.85 ground transmitter in Connecticut can be heard.  It is very weak right now but with some antenna tweaking and the addition of a second antenna reception may improve.

4) zbw dj Feed (Boston Center High Alt Sectors)

This feed is currently focused on the Boston Center high altitude sectors covering inbound Atlantic arrivals.  No real change here - reception should be somewhat enhanced but it is hard to verify.

All these feeds are down at the moment due to a system issue.  Hopefully back in 24-48 hours.

The reception does sound better on this feed. However there is a problem with the audio in that there is now splashover from the other Boston Center feed coming through in the background. While the splashover is not quite as loud it is very noticeable (distracting). DJ

It has been that way for awhile DJ.  I didn't want to be the one to bring that up since there are some here that think by me bringing up things that I am a bit pushy

From what I remember previously, the splashover was coming through on the Boston Center Misc feed, now it's the other way around, coming through on the Boston Center High Alt (Atlantic) feed. DJ

I noticed it during the install but ran out of time at the site.   I will see if it is something that can be fixed by playing with the Linux audio mixer remotely.  Otherwise I'll work on it next time I'm there.  It is definitely annoying and I don't recall hearing it before.

Appreciate your efforts Dave, from what I've heard so far it appears to be an excellent location, the reception on 133.450 is much improved (hardly any interference now). DJ

Still hearing the Misc feed splashing through on the High Altitude (Atlantic) feed, actually sounds worse than before. DJ

Just checked it again now, no change. When listening to the High (Atlantic) feed I can hear the Misc feed in the background at about half the volume. The same when listening to the Misc feed, I can hear the High (Atlantic) feed in the background at a lower volume. DJ
