Communications Power Inc. (CPI) model CP-2000 vintage AM/SSB CB base station

This is the CP-2000 transceiver made by Communications Power Inc. (CPI) in the USA. This radio was sold from 1977 to 1981 by CPI. It is the only CB radio on the market (then and now) that is designed as a professional HF radio. As a results, the specifications and associated performance are phenomenal (but so was the price tag in 1977!). To name a few, it has an adjacent channel rejection of more than 70 dB. SSB mode has a true 2.3 kHz 8-pole crystal filter, and a 6 kHz crystal filter for AM (combined in a single case). The RF power amplifier is designed as a wideband amplifier and uses a professional stripline transistor also used in military radios of the time. It is robust against infinite SWR. Modulation is superb in both AM and SSB mode, and uses a built-in speech processor to increase talk power, something you will normally find on professional HF radios not not CB radios. The AM mode has the best ALC (automatic level control) I have ever seen on a HF radio, completely eliminating over modualtion. The receiver uses a J-FET high-level mixer in the front-end and is very sensitive. The receiver AGC function works perfect (so you don't constantly have to fiddle with the volume control between weak and strong stations) and S-meter, wattmeter, VSWR meter, squelch and RF gain control are the best I have ever seen on any CB radio. Last but not least, the noise blanker on this radio is the best I have experinced on any HF radio, it works even better than the one in my $3000 Icom ham transceiver. To summarize: This without a doubt the BEST CB radio that was EVER sold, then and now. Period.
