Printed Circuit Board PCMA001S

I make a special EPROM expansion board that will add 4 more bands to many radios that use either Binary or BCD programming, it also adds a 10KHz shift function as well, click here to find out more.

It will give 1 band down, 1 band up, UK 40 (up 64 channels without Alpha ch hops), NZ 40 (down 63 channels) and 10KHZ shift.

On a 40 channel radio it will give coverage from 26.335 to 28.005 (including the normal low,mid and high bands of 26.515-27.855), that is a total of 167 channels !

I can also make a custom board upon request which will give whatever frequency range you want (within the limits of the radio).

Modification for SuperStar 2200

To get 10-meter, cut trace from + 5 Volt to Pin 8 and 9.
To get 12-meter, cut trace from GND to Pin 7 and connect Pin 7 to + 5 Volt.
Re-tune both Transmitter and Receiver-part.

VCO operates between 17.115MHz (Ch.1 Band A) and 18.445MHz (Ch.40 Band E),
output on Pin 6 is 36.780MHz (Ch.1 Band A) to 39.000MHz (Ch.40 Band E),
and output on Pin 9 is 2.550MHz to 2.110MHz in all band.
The VCO-voltage (TP1) operates between 4.5 Volt (Ch.1 Band A) and 0.5 Volt (Ch.40 Band E).
