Sidetone etc. - DX-60, ADD a TICK keyer

[Fred Finster]

If you are listening to this list, you are probably interested in KIT
building.
Mostly Heath Kit building.
So my simple answer, get a tiny TICK kit and mount the board in side the
DX-60 to create your side tone and drive your DX-60 transmitter.  The JUNE
99 issue of QST showed a Twin T oscillator transistor circuit to create the
sine wave tone, too  (or was that the Yellow colored issue of Ham Radio with
the QRP Card File receiver).

Here is
my suggestion for sidetone with a straight key or bug with the DX-60.
Rectify some of the filament voltage 6VAC or 12VAC with a DF04 bridge
rectifier and a 10uf cap and 0.1uf RF bypass cap.  Now use the ~14Vdc to
power the 78L05 on a Tick Keyer IC KIT.  Put the keyer in straight key mode
using the push button switch.  Side benefit of TICK is the "TUNE" mode.
Since the DX-60 is probably negative grid voltage keying.  Look at my
website
for a PDF file showing how to add 3 resistors and 1 PNP transistor to the
TICK to
key a negative grid voltage.  Also check out the "gridblok.htm" Jackson

PS.  Using a transistor and resistor to drive a speaker gave better 700Hz
tone than with
        the piezo that comes with the TICK Kit.
