A printout of the two different manuals for this radio downloaded from old Qrpkits site is included. 040, MHz with a small pulverising capacitor to shift the frequency few khz up and down. It has 8 xtals with a rotary switch 7.
I'm selling this to clear out the clutter avoid becoming a hoarders episode. Offered as-is, nominally for parts or your repair modification pleasure. It includes crystals a built in antenna tuner, among other doodads.
There is an unfinished random wire antenna tuner inside the box with led Sr meter. Not exactly a backpack field qrp rig but it does have possibilities. There is room inside the box as shown for a power sonic PS-1251fp rechargeable battery not included.
I never got the Ati to work properly and tired of messing with it. The Ati can be bypassed so output comes out NBC connector on front panel. This is a Qrpkits DC40 transceiver built into repurposed extruded aluminum b switch box.
