SSB Adapter for Hammarlund Super Pro SP-600 - $142 - (Godfrey, ON)
These are great AM receivers. With this adapter installed, they become great SSB receivers as well. All controls work as before, and AM performance remains the same. You mount the adapter under the chassis, remove some components, install two small capacitors (included), and connect eight wires. No drilling. When the BFO is turned on, the single-balanced product detector and dual-time-constant AVC circuit are switched in automatically. With the BFO turned off, the original AM detector and AVC are restored. Significant under-the-chassis work is required. We recommend that you go to http://www.treetopcircuits.com/docs/SB-600-Manual.pdf Normal 0 false false false EN-CA X-NONE X-NONE and download the owner's manual before buying. This is about a 1.25 megabyte file, so it may take some time to come down on a slow Internet connection. We'll also be glad to respond to questions.
