Small Wonder Lab PSK-20 $100

This is a used Small Wonders Lab 20 meter SSB transceiver. This is a single conversion,
xtal filtered, transceiver. Coverage is 7.070mhz to 7.073.5mhz covering the digital
portion of 20 meters. Power output is 3 watts with 13.5vDC. The 4-pole xtal filter
sharply falls off outside of the specified frequencies, thus rejecting strong signals
that may overload the receiver. A digital audio signal (BPSK, THOR, MSK,etc.) is fed to
the AF-IN port. The PSK-20 automatically switches to transmit when it detects audio on
the AF-IN port. Any received signal in the passband is produced at the audio level
through the AF-OUT port. I recommend FLDIGI (free) as the most comprehensive digital
signal processor and decoder of digital signals. IN and OUT. 3.5mm audio jacks. A blue
LED is always on when DC is applied. This is the only mod to the unit. Includes manual.

Plus shipping from 15626. PayPal preferred. Shipped continental USA only. FT-707 not
included!
