Motorola Cm300 Vhf4/21/2021
The specs for the model I was given list the frequency range as 146-174Mhz.However, many of the VHF repeaters I would like to contact are down in the 145Mhz range, including the repeater closest to me.Is there even any point in putting frequencies in the 145 range on my frequency list I know the radios is not technically specified for those frequencies, but I seem to recall other radios Ive had which would transmit and receive just fine on frequencies a little outside the range in the radio specs.It was in great shape, it came with all new accessories (microphone, mounting bracket and power cord), it had a split that included half of the 2 meter band, supported wide and narrow FM modulation (more current radios only support narrow FM and sound weak on ham bands) and the price seemed right (100 shipped).
Motorola Cm300 Vhf Software And CableI quickly Googled the radio and found that it was 32 channels, 45 watts, covered 146-148 MHz and it appeared that CPS radio programming software and cable were readily available. I pulled the trigger and sent the seller the requested payment, 100 via PayPal. I choose to use Family and Friends option on PayPal so the seller got the full 100, I paid the PayPal fee myself and lost any buyer protection for the transaction its a choice I made, no regrets.). A quick Google and I turned up the needed adapter, Mini UHF male to SO-239, at a local retailer for 5 excellent While in the store I picked up a few other items a Tram NMO magnet mount that came with 17 of coax with a Mini UHF connector (about 25) and a power adapter to convert the Bullet power connector on the back of the radio to the ubiquitous Anderson Power Pole connectors (8). For those of you keeping score, Ive invested 100 on the radio, 5 for the antenna connector adapter, and a purely optional power adapter (8) I easily could have crimped a pair of Anderson Power Pole connectors on the supplied power cord so Im almost 120 into this radio. I decided to risk the few dollars the cable cost and put my trust in the positive comments from previous buyers for this specific cable and this specific radio model. I then went to a website called and downloaded the Motorola RP05 software after registering on the site. After installing the software, I powered up the radio, attached the radio to the computer with the eBay cable, and everything just worked it quickly downloaded the current programming on the radio. The channels were easily written to the radio, and the programmed channels all worked as expected success I quickly added a half-dozen more local repeaters, set the scan list for the radio, and programmed the few programmable buttons on the front of the radio for functions like Scan OnOff and HiLo power. Exploring the software a bit more, I found there was a capability to print out a cheat sheet on the programmed channels and programmable button settings what a neat feature I wish the various Chinese DMR radios and Japanese FM and digital radios had similar capabilities. But at the end of the day, I invested about 120 and put in a fair bit of work to make the radio work on part of the 2 meter band (remember, the radios split only went down to 146 MHz) with 32 channels and 45 watts RF output. For a few dollars more I could have gone to my favorite local Ham retailer and gotten a radio purpose-built to work the 2 meter band with higher output and way, way more channels But I have no regrets I got a great radio, learned a bit about the Land Mobile radio service radios, and now I finally have a pristine 2 meter radio I couldnt be happier with my purchase. If I had to purchase programming software for this bargain radio it would have cost me 300 for a three year license. At three times the price of the radio, I would have had a hard time justifying the purchase, even though the software supports numerous Motorola radios, I only have the one radio. While it is illegal to copy the Motorola software, it is perfectly fine to take your radio to a friend that does have the Motorola software and ask them to program your radio.
