Good day All.
My Ebay lucky-dip FRG7 has arrived, and its what I hoped it would be, see pics below.
There are a few things that Im struggling to identify, so if anyone has any input, that would be great, thank you.
?
The serial number has extra digits, so if anyone recognises the number, please shout up.
Serial number: 17 8M 240615
?
The PCB marked DL6 SW 004 is power from the DC rail, it 'seems' to have an SO239 on one side and a BNC on the other side, no connection into the unit itself at all. SO239 SW2 is no longer connected to SW1 or BC. Does anyone know what this is please.
The XTAL is 38.66667Mhz
?
There is something that looks like an additional modulator marked astec, does anyone have any info on this please.
?
At the moment, its powered up, white noise when AM is selected, the lock LED will go out above 15Mhz ish but wont go out below.
Putting a TinySA outputting at 25Mhz with 100Khz AM-mod near the antenna plugs induces the signal at 25Mhz and is auditable.
?
That's about as far as I've got so far.

Br John.
