President McKinley EXPORT AM/FM/SSB CB Mobile Radio 20W SSB, 12V/24V

President McKinley EU EXPORT TUNING

CB radio with improved broadcasting and export mode enabled

A number of modifications made:

- Output power adjustment: AM up to 10W (20W PEP), FM up to 20W, SSB up to 20W PEP

- Unlocking to Export version - 24.710-30.105MHz, 0/5 rasters, multi-standard off

- Replacement of filter II HF on a better quality Japanese ceramic filter muRata 455 HT - improved selectivity (this applies to samples without this filter)

- Improving AM modulation - increasing the transmit volume - no gain microphone is needed

- Modification of the AM modulator adding treble in the transmission path - more "sharp" modulation

- Tuning / checking the radio receiver - checking / tuning the receiving path.

- Filter replacement for a better quality 10.695 KNKTR quartz filter - improved selectivity, reduced noise
