It's on one of the ZBW feeds under Class D/Center feeds - named "ZBW - Boston Center High (Atlantic traffic)."

Here's the list of freqs for the feed:

High Altitude Sectors:
Augusta Sector (AUG 02): 134.95
NOTE: Interference
Nantucket Sector (ACK 17): 133.45
Boston Sector (BOS 46): 127.825
Cape Sector (CAPE 18): 128.75
ZNY - New York Center (High Oceanic): 125.925
Plattsburgh Sector (PLB 53): 118.82

It is covered from my home receive site, which gets great reception but is not close enough to hear the controllers on those frequencies since those transmitters are out of range.

which gets great reception

The reception in the lower and far southwestern portions of the 128.750 sector are actually not that great, just because of the low altitude and distance from the radio. For example PVD departures southbound routing via JUMPR and the MVY 260 radial to SHLEP and RIFLE pass through this sector, usually checking in climbing out of around between 7500-9000 feet for 10000 feet, although readable in most cases they come in very weak, which only makes sense given their low altitude and distance of around 75 nautical miles from the radio. Same with reception of handoffs from 128.750 to Boston Center (135.800/124.525) to the southwest in the lower altitudes. Unlike most high altitude sectors that are floored at FL240, the 128.750 sector appears to be floored at 11000 feet (can anyone confirm that ?). DJ

This ZBW sector (Nantucket Sector 17) goes all the way to the ground in certain parts of the sector.

This is the worst direction for me (southeast through southwest).  This feed and the several others (except for HF) that I host will be moving by late summer to a hilltop location that has a 360-degree clear horizon and is above all the surrounding terrain.  The location will be Harvard, MA and the antenna will be about 100 feet in the air or higher, fed with Heliax (hardline) and a preamp.

Sounds good, looking forward to that ! DJ

I went to assess the site tonight on airband.  I am already pretty familiar with the site's capabilities from past ham radio activities.

Using an existing 146 MHz antenna (too short to be resonant on airband) at about 70 feet in the air, and a very low loss feedline (hardline), I was able to pick up the following interesting things:

- All the Boston Center transmitters in Woodstock, CT (133.425, 127.825, 124.85) - ~52 air miles
- Boston Center transmitters from Gardner, MA (123.75, 134.7) - 25 air miles
- All Boston Tower and Approach facilities (a/c on the ground at Boston barely audible) - 27 air miles
- Everything at KBED (including all a/c on the ground, and loud); KBED virtually line of sight and 12 miles away
- Worcester Tower and Bradley Approach 119.0 - 20 miles away
- Providence Approach 135.4 - almost 50 miles away

I didn't have time to check much else...some of the Center frequencies I wanted to check were too quiet at that time of day (e.g., 128.75).  There is a reasonable chance of picking that up when I put a real airband antenna on the tower.

I will install a scanner beam (pointed southwest toward CT) and a plain aviation band vertical at the 75-80 foot level on the tower in the next two weeks.  I plan to power-split them initially but eventually may just have them feed two separate banks of scanners.  The tower already has spare hardline (very low-loss coaxial cable) installed.

This will be an excellent receive site with many feeds coming from here in the next two months.
