What a great quality radio and accessories you have! Wow, I'm impressed and am thinking, I'll have to keep my eyes peeled when helping folks downsize and clean up their homes, basements, garages and shops. My wife and I have helped many families and friends clean out and sell items for them after the passing of a loved one, having to move to a care facility, moving into a smaller home or moving across the country. We come across lots and lots of tube type vintage radios as well as vintage solid state radios and devices, boxes packed with nos tubes and such. I will go through the tubes carefully to log all the numbers and letters of each tube and then id the tubes for their uses, list them for sale and into a customer's hands that needs a specific tube. Thank you for your informative videos on the CP2000 radio and accessories! It's appreciated at least by me!!
my Dad had the Radio and Freq. counter and I think the Mike. I KNOW He DID NOT Have the Watt meter. Had it about a year than traded it for something else. this is the one Radio I wish he would have kept as I really liked it.
I got bored during the pandemic and had been computer modeling this antenna for about a year, decided to build it but my Asian supplier went missing whom was going to supply me with very lightweight hollow fiberglass fishing blanks. I ended up ordering $20 worth of bamboo from Amazon I couldn't be happier if it's a real conversation piece on are and gets the job done extremely well for a fraction of the cost:. 73-Gregg s9radio ua-cam.com/video/iwx3pke5JZc/v-deo.htmlsi=QYfRmYt_D3DA4WxZ
A stock CP2000..... My CP2000 has an additional rotary switch installed between the power switch and mic connector. The mounting hole for the rotary switch is already there from the factory. There is also another rectangular hole near the transmit LED for an additional slide switch. Besides the frequency counter, there was a monitor oscilloscope.
I struggled to believe that is factory as I've owned several CPI's back in the day and serviced several as well. I am however familiar with the monitor scope as well as the amplifiers it were available as add-ons for the station I'm not sure why CPI would even entertain the possibility of rotary power switch as there's really only one point that the CPI has great audio with a little extra power which is definitely less than 10 watts and if you exceed that the modulation goes to hell and I don't think the factory would ever do such a thing (thrashing the radio's audio). Love to see some close-up photos of these mods and I could easily tell you whether they were factory or not however it's pretty doubtful they were. 73-Gregg s9radio
@@s9radio it’s not a rotary power switch. There was a kit board which would take the cp2000 beyond channel 40 up to 99. If I remember correctly it also added duplex frequencies/channels. With an external power supply, I believe output can be 25 watts at 100% Modulation. However a heat sink must be installed on the RF output assembly otherwise it will heat rapidly and shutdown the output driver and finals.
@@DandyDon1 A simple double throw double pull toggle switch is all that is required to turn the 40-ch CPI into a 120-ch radio going up 40 or down 40. The stock CPI will do 25w without breaking a sweat as the driver & final have plenty of heatsinking as mentioned in the video. Yeah a 30 minute key-down might get things a little warm and the active bias I also mentioned in the video self adjust both the final & driver preventing thermal runaway. The CPi's modulation circuit tolerates a max of about 12 watts AM carrier before back-swing becomes an issue. Anyone thinking about modding a CP2000 beyond extra channels should have their head examined as they are perfect box stock and capable of more forward swing than most solid-state rigs by leaps & bounds. You can dial back the driver circuitry to 2w and swing well past 20w if you want. I find the BC2000 runs best at 6w for the best sound. 73-Gregg s9radio
@@s9radio I'll need to take the box out of the upper storage cabinet where my CP2000 is. The original shipping box, as I bought it new in the 1980s and take some pictures of the kit which was installed. Not sure if I still have the installation instructions somewhere. I do not doubt it cannot be done without the PWB and wiring installed, but I do believe this was the way it was done at the time. The only thing I don't care for is that the NB was (disabled I believe) for the 5Khz drop switch, which can be easily returned to original. At the time it was explained to me that even though there is a knockout stamped into the front face plate near the transmit LED from behind, it is nearly impossible to remove.
@@DandyDon1 sorry to hear someone has disabled the NB. CPI / Motorola engineers were proud to boast they had created what they believed was the best NB in the business and I concur. It outperforms many modern day amateur rigs NBs.

Hi there in England here....Can we see your bamboo Quad..?
