Guppy Still Swims

The Guppy from the NOGA QRP Group provides
Transmit / Receive Switching for QRP separate rigs.

My version of the Guppy

This little item is extremely useful if you are trying different
QRP Receivers and Transmitters.  It is a kit based on the original
board by W1FB in QRP Notebook and a QST article.

It has made a ‘Rig’ out of my NS-40 from 4SQRP Group and
the MRX-40 Receiver from QST :

NS-40 / MRX-40 prior to packaging

After modifying the MRX-40 to include a Mute circuit,  QSO’s
have been great.  Still working on a Spot switch for the NS-40.
