KX7N Amateur Radio

The station

The Shack

A practical mix of modern HF capability, VHF/UHF coverage, QRP gear, favorite paddles, and just enough computing power to keep the digital modes moving.

Inside

Radios and supporting gear.

Every part of the station has a job. Some equipment is current, some is classic, and all of it is here to be used.

HF station

Primary radios

  • Yaesu FTDX10
  • µBITX
  • Heathkit HW-7 QRP rig
VHF / UHF

Local coverage

  • Icom 2730
  • Tram 2m / 440 MHz vertical
Supporting gear

Tuning and power

  • HW-201 amplifier
  • MFJ antenna tuner
  • Daiwa SWR and power meter

Outside

A deliberately simple antenna system.

The HF wire covers 80 through 6 meters. It runs through a tree to the far support, approximately 20 feet at each end and 40 feet at the center.

It tunes where I need it across the working bands except 160 meters. On 75 meters I use the manual tuner; elsewhere, the FTDX10’s internal tuner usually handles the job.

Antennas
  • 80–6 meter end-fed wire
  • Tram 2m / 440 MHz vertical

Keys and computers

Paddle collection

They all get used, but the Vibroplex Blue Racer and my other Vibroplex paddles remain the favorites.

Digital desk

Mac mini & Raspberry Pi 4

The digital modes run on a Mac mini or Raspberry Pi 4. The microphone is rarely invited. Neither is Windows.

On the bench: the µBITX

My µBITX has already received its share of upgrades. The next planned addition is a built-in digital SWR and power meter—another useful reason to keep experimenting.
