Digital dial c-drake for R4A/b/c plug-n-play
C-Drake: Digital Frequency Display for Drake R-4A/B/or C
Now with TCXO reference oscillator for exceptional accuracy and stability.
Plug and Play on R-4A/B or C (shown here on top of my R-4C not included)
C-Drake display contains power rectifier / filter and regulator. Goes on / off with the radio.
Displays frequency with 10Hz resolution
Fully automatic. It measures the INJ port RCA jack.
Installation consists of connecting to INJ jack using supplied cable.
Power can be obtained from the radio's filament voltage on the AUX Power connector.
(Mating power connector for the C-Drake is included)
For use with a T4 and RCA jack is provided to make a "Y" connection to the INJ port.
The preselector control must be tuned reasonably close to the band being used, which is of course true anyway.
If C-Drake does not operate properly on a band it will be necessary to peak the premix circuit, for that band, as shown below.
properly on a band, after adjusting the
preselector control on the front
panel, it may be necessary to peak
the two premix circuits, for that band.
