Many thanks to Randy (K8ZFJ) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, read this post. Check out Randy’s field kit:
Penntek TR-35 SUV Field Kit
I built my field kit around the venerable Penntek TR-35, mounted in a Pelican-like case, including the
- CW Morse Pocket paddle,
- a 4 memory K1EL keyer,
- QRP Guy’s swr/power digital meter,
- rechargeable Satechi mini round speaker (similar to this one),
- and a cheapie digital clock.
A single 3S LiPo battery with Anderson Powerpoles powers the TR-35 and keyer. All 53 , Rhode Island POTA parks were activated using no more than 4 watts.
The homebrewed EFHW antennas and feedlines are stored separately in an old camera bag. One End-Fed Half-Wave (40/30/20) uses the SOTAbeams Pico traps , another is a linked 20/17 meter variety. Both use stacked FT50-43 toroids to construct the ununs, mounted on plastic perfboard like winders.
The antennas have been deployed as slopers, supported by a 32′ telescoping fiberglass mast and mounted in wood and PVC holder that slips into the trailer hitch. This approach takes up minimal real-estate, is easy to set up and the operating position is either from the rear hatch or inside the vehicle.
