Make your radio new again!
DDS-VFO kits are out of this world and the best way to upgrade or expand your old radio so it has a
new life and look.
This is a great project for those of you who want a full functioning VFO for your radio. It can be as simple or as full featured as you like. Lets say you have a favorite radio but the Pll is dead and it will cost a lot to repair it, no problem, with the DDS-VFO you can, and cheap! Another example is your Channel display is out and you don't want to pay the high price of getting a new one, no problem...just slide in the DDS-VFO and your done!
The new version has been fully customized to adapt to various radio models, including HF radios. This version allows a frequency adjustment for bandwidth mode with limits from 0Hz to 99MHz, it also allows removing the Channel mode and Radio Receiver mode, remaining exclusively for a VFO mode.
In general, this version has:
Channel Mode, VFO Mode, display your call sign, band Scan, spectrum scan, selectable
channel scan, priority scan
HF Receiver Mode (mixer not included, but easy to build or purchase from us!)
Polyphonic roger beeps
A settings / Service Menu with 29 items
includes several adjustments that can be made by the user, such as:
lock / unlock clairifier, choose between roger beep tones or leave in a random mode, Turn on / off frequency in Channel mode, limit TX time, control brightness of screen, set high and low frequency range, 2nd output for Transverter to name a few.
