The Icom 9700 with an SM-20 microphone is used for VHF/UHF FM and SSB/CW weak signal work:

On 2 meters, the output of the 9700 is fed into a Mirage B2518G amplifier and with about 25 watts input, produces about 150 watts into the antenna according to my MFJ-849 and Diamond SX-400-watt meters. The amplifier is keyed using a cable and amplifier buffer produced by Dan, W7RF.

K9WK Yaesu FT-736R

A Yaesu FT-736R is used for 144 MHz, 220 MHz, and 440 MHz all mode operation. I was very lucky to be able to find a 220 MHz module for this radio.

K9WK Bridgecom 220 Radio

A BridgeCom systems BCM-220 transceiver is used for 220 MHz FM. It is built like a commercial grade radio. Heavy duty with a front firing speaker. Plenty of receive audio and easy to program.

The vintage equipment on the upper shelf consists of a Heathkit HD-1410 electronic keyer, Heathkit HG-10 VFO, Heathkit DX-60, and a Lafayette HA-700 receiver with the matching speaker.

The shelving unit on the left contains a Radio Shack Globe Patrol shortwave receiver, a Lafayette Explor-Air Mark V receiver, a Lafayette Comstat 25A with a Turner +2 microphone, an SBE Console II with an SBE amplified desk microphone, and a set of Lafayette Dyna-Com 23 walkie talkies.

I use a Vibroplex Square Racer Deluxe for CW:

On HF SSB, I use the Yaesu M-100 microphone. I set the AMC level at 40, the gain at 50 and the processor level to 40:

K9WK M-100 Microphone

I use the following switch settings on the M-100 microphone:

  • Dynamic element (D).
  • LOW CUT set to ON.
  • HIGH CUT set to OFF.

​The menu settings on my FTDX-101MP are:

  • MIC EQ: ON
  • SSB TX BPF: 100 - 2900
  • ​SSB LCUT FREQ: 100
  • SSB HCUT FREQ: 3000

The receive AGC is set to MID, and the roofing filter (RFLT) is set to 3kHz.

These settings may or may not be to your individual taste, but they sure work FB for me!
