I'm not sure whether that radio uses one crystal per 40-channel band or a combination of fewer crystals and PLL code manipulation via PROMs to generate all of its bands.

With the age these radios are now, if a decent one came into my hands I would actually restore it to its original channel / band range, whatever that was.
Hi SH,

ok the Nato 2000 has five crystals...

Frequency range:
Band A: 26.065 to 26.505 MHz
Band B: 26.515 to 26.955 MHz
Band C: 26.965 to 27.405 MHz (FCC band)
Band D: 27Л15 to 27.855 MHz
Band E: 27.865 to 28.305 MHz
Band F: 28.315 to 28.755 MHz

In some models, Band E is called "FM" and contains the UK CB band of 27.60125 MHz to 27.99125 MHz, with no Band F.

Band A. Adjust CT-1 for 19.655 MHz
Band B. Adjust CT-2 for 19.880 MHz
Band C. Adjust CT-3 for 20.105 MHz
Band D. Adjust CT-4 for 20.330 MHz
Band E. Adjust CT-12 for 20.555 MHz

Band E may contain the UK-FM band, in which case crystal is. 20.423 MHz.

Some models may contain only 3 crystals of 19.655 MHz (Bands А & В), 20.105 MHz (Bands C & D), and 20.555 MHz (Bands E & F)

The Nato 2000 has a unique channel selector from what I understand?

This radio is rough, cracked/broken/scratched fascia... missing knobs etc.

Definately not one a collector would be interested in... put it that way!

I can use the 10m band so would not feel bad about making it more useable for me.
