Printed Circuit Board number PTBM133A4X

I make a special EPROM expansion board that will add 4 more bands to any PLL02A radio, 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).


Circuit Theory

Oscillator frequency
VCO-frequency = Oscillator frequency (Q2) - FIN
VCO-frequency = 20.105MHz - 2.55MHz = 17.555MHz @ Ch.1 Band 40
Output from BPF (T1 / T2) = Oscillator frequency (Q2) + VCO-frequency
Output from BPF (T1 / T2) = 20.105MHz + 17.555MHz = 37.660MHz @ Ch.1 Band 40
RX and TX frequency = Output from BPF (T1 / T2) - IF-frequency
RX and TX frequency = 37.660MHz - 10.695MHz = 26.965MHz @ Ch.1 Band 40
