    Picked this up yesterday.

    I asked the guy - are you the original owner, and he said yeah I used to work there. Turns out he used to test and build the units. The frequency counter was one he built that was never released he thinks. I’m going to try to get more information from him and document it if possible. Would love to get some stories and behind the scenes insight into the factory.



    23 channel but had the mods for extra frequencies.

    crazy thing is the power microphone - it’s a old turner 70 which woody and I had just been discussing in another thread! Turner did a CPI version.

    There’s something I’d never expect to see, much less get a chance to own. Congratulations!

    Nice! Get any documentation from him you can, it's probably the last chance for most of it.

    I emailed him today - hoping I can do an interview with him. Made some contacts to Cali with it today. Not much output (5-7 watts PEP on both AM and SSB) but the stock microphone is a bit lacking in gain on the lows. Audio sounded nice though on the SDR but I'm really excited to test out the Turner Road King 70 version on it but have to wait for the 7.5V battery I just ordered.

    I have to say switching between this and a Uniden 980 the CP300 has a really nice sound to it, super crisp and less static - the external speaker in the base power supply is really booming, barely have to turn up the volume.

    The two knob channel switching is more intuitive than you'd expect. I can go to 27.555 or 27.025 really easily. In many ways it's almost easier than a 40 channel single knob because you don't have to flip through a ton of channels.

    Awesome radio, two channel knobs like that Palomar. I wonder how much they have in common?

    CPI built the Palomar DigiCom 100. So they probably share a component or two.

    Here's some info on the 300. Also if the radio has a green dot on the TA sticker on the back it was modified at the factory for improvements for the noise blanker, ambient noise level and modulation warble on SSB.

    And, they don’t make them liked they used to: 7-lbs, according to that spec sheet.
