TSRC has plenty of projects underway - see one that interests you? We always need help, and it's a great way to learn new skills or add your own.

The New Support Trailer is Under Construction!

It's a 7'x16' all-aluminum Nitro cargo trailer with an RV side door and drop-down rear ramp. It will haul many of the club's "toys" and provide space for an additional operating position for Field Day or large public service events. Right now, the Trailer Committee is working to design and build the interior fixtures and plan the modifications and installation. When done, it will have: 

  • 7' workbench with parts and tool storage drawers
  • On-board battery and charger/power supply
  • AC power center
  • Bright LED lighting inside and out
  • Carpeted interior walls, painted floor panels, both sides
  • Storage for multiple HF beams and VHF/UHF verticals
  • Shelves for radio equipment cases, test gear, APRS trackers, etc. 
  • 2 NMO antenna mounts
  • Forward and aft cable entry ports
  • Folding tables and chairs
  • 10'x15" canopy
  • Both AB-577 military towers
  • Cables, push-up masts, sandbags, portable lighting, and more
  • Room for a generator and fuel
  • Exterior graphics will be similar to the existing Communications Trailer's

Take a look at the current floor plan design (not to scale and in constant flux - hey, it's a design-build!)

(If you have a 2" drawbar hitch and electric brake controller on your full-size pickup or SUV, AE1H would like to hear from you!)

Communications Trailer Upgrades and Maintenance

It's 13 years old! Doesn't seem that long. We're doing some maintenance and upgrades to make it more functional and to overcome some limitations.

  • DC power wiring up-sizing to eliminate voltage drop with high-power radios
  • New better-shielded coax cable to the operating position's connection boxes
  • Oil undercoating to slow frame rust
  • Corrosion repairs
  • Replaced the old white-board with a new magnetic one
  • Carpet repairs and cleaning
  • Upgraded network and WiFi mesh network capability
  • Permanent antenna patch panel to replace old "temporary" panel
  • Battery box, master disconnect
  • Long-term (we hope!) planning for a larger replacement trailer
Contact Al, AE1H for more information.

Field Deployment Kits
As a result of several large equipment donations, we're also now building some task-specific kits, such as one for Summits On The Air (SOTA) and US Islands activations, and a Winlink Pactor 3 go-kit. Do you have any ideas? Contact Dan MacMartin AD1HD.

New Repeater Site
Work is underway on a third linked repeater site in S. Strafford, VT. It should have excellent coverage in the Upper Valley and well into Vermont. The club's portable repeater is currently operating at low power from a nearby garage and the full system should be on the hill as soon as we have the power line and equipment shed completed - hopefully before winter! The DB-224 antenna and 1/2" Heliax feedline have been installed at around 80' on the 100' tower (pics to the left.) Information on the new repeater will be shared with members via the email list. Contact Dave N1HAC, TSRC Repeater Manager.

Repeater Upgrades

The old GE Mastr II repeaters in use on Moose Mt. and East Corinth are in need of replacement due to an increase in maintenance needs. We're in the process of acquiring and modifying newer Mastr III repeaters. At the same time, we'll be installing a new S-Com 7330 repeater controller to replace the aging and somewhat funky Link RLC-2 on Moose Mt. Contact Dave N1HAC.

Inventory Management System

With a steadily growing equipment inventory, Steve and Adam Goldsmith are working with the BoD to develop a simple and easy to use inventory database and labeling system. The goal is to make the annual inventory much faster, and help track equipment locations and status when needed.

Tower Trailer

Our venerable old military tower trailer is in need of some maintenance and paint, and a bit of body work. We're hoping to get a body shop to fix the fenders. Rust clean up and new paint are next. Contact Al, AE1H.

Amateur Radio License Test Prep

In conjunction with the CVFMA ( we're planning to offer one or more Tech license classes and exam sessions soon.  We're also training up some more Volunteer Examiners (VEs). Contact Ray WA1ORT for more information.

Digipeater/iGate Expansion

To better support local public service events like The Prouty, Vermont 100, Vermont 50, Covered Bridge Half-Marathon, and others, we're building out the network of APRS site. If you'd like to host either a digipeater or iGate station, get in touch with Steve W1HS to see if your site is appropriate.

HF Beam "Portable-izing"

We have two HF and one 6m beam to make fully portable, This involves permanently attaching boom saddle-blocks, slitting element ends and adding thumb-turn hose clamps, etc. If you've seen our portablized Moseley Mini-33A beam, you'll know what the goal is. Hopefully we'll get a crew of three or four together this fall or next spring. Contact Dave, WA1ZCN.

Mesh Networking Kits

Steve W1HS has been putting together a deployable Amateur Radio 5 GHz mesh network. This will be used at Field Day to connect logging computers, and can be used for public service events or ARES emergency operations.
