Version
3.03 Dual VFO for PIC16F88 processor
08.10.2005
VFO A is in use when PIC16F88
pin #4 is high, this is the default (pull up resistor). VFO B is in use
when pin #4 is grounded. The active VFO is indicated by two different decimal
separators in frequency display. Dots means VFO A and commas means VFO
B. Both of the VFOs can be set independently to a desired frequency in
JUMA-RX1 range. Save function will save the frequency and the step value
of both VFOs. A switch which will ground the pin #4 is needed for VFO selection
see example. It is recommended to change the
R21, 1k resistor (pin 4 - VCC) to 10k. There is no problem with the the
1k resistor, it just consumes 5 mA more current when VFO is in use. See
another picture of dual VFO connection.

Version 2.01_88 (Experimental
version for PIC16F88 processor) 28.08.2005
This is a beta test version v2.01
for PIC16F88 processor. It has more program memory (Flash) but the code
is not exactly compatible with the PIC16F819. The version has one additional
feature, there are now four frequency steps 10Hz, 100Hz, 1kHz and 100kHz.
Please check your prommer compatibility with this processor. We had to
make an adapter for ICD2.
