Four years after its initial design, the VGC 6600PRO has evolved into the BTech UV-50X3, a full featured Tri-Band mobile that delivers a full 50W on VHF and UHF, with addition of a 220 MHz module that delivers 5W output. The 220 MHz module was specifically designed and filtered for 222-225MHz US ham band operation. I mention this as there are currently radios being advertised as Tri-Band operating in the range of 240-260MHz that are not adaptable to frequencies below 240MHz due to their internal filtering.
Included with the radio are:
50X3 Weight: Main Chassis 2.1kg (4.6 lbs)
The 50X3 is FCC Part 90 certified for commercial use in the US.
The suction mount is about the best I’ve ever used. It requires a smooth metal or glass surface, but the silicon rubber cup will not let loose. My control head has been mounted atop my computer for over a month, and it is going nowhere.
The button functions are displayed on the LCD screen for easy function identification. The PTT button on the upper right is for Momentary or Toggle PTT. One press turns the TX on, next press turns it off. Setting to Toggle is convenient if running a net or using a mobile headset.
The 220 ham band transmit range is limited to 222-225MHz. The receiver is capable of being programmed above and below those frequencies, but may be outside of the performance range due to the ham band specific filtering.
The radio comes with a full function keypad style microphone. On the right side are two slide switches that control the Lock and Lamp feature, and on top of the microphone are two frequency Up and Down buttons. Along with a 16 button DTMF style keypad are 4 programmable function keys. Choices are Squelch Off, TX Power, Rptr Shift, Reverse, and Tone Call.
There are two microphone input jacks. One on the control head, the other on the main unit. There is also a built in microphone element inside the control head. Although the audio quality is excellent, the sensitivity is that of a standard microphone. The OTA reports were excellent with plenty of audio, so there’s no reason to shout.
A nice feature in the audio section is an adjustable microphone gain control. There are 5 settings available. Min, Low, Normal, High, and Max. Normal is great for speaking in a normal volume an inch from the microphone. Running a net with VOX and a headset, you can bring it up a bit. Driving in an off road vehicle, you just might need to set it back.
Along with the standard VHF / 220 / UHF frequencies, the receiver covers:
0.5-1.7 MHz (AM Radio)
The control head has built in speakers, as well as one in the main module. An external speaker jack in the rear also allows for a larger speaker if desired. The jack provides for either mono or stereo output. (each receiver can have it’s own speaker). I found a menu setting to adjust the tone of the speaker as well. Although there is more than ample audio output, when the volume control is all the way down, the radio is silent, as it should be.
Cross Band Repeat
The radio takes full advantage of the independent receiver by including a Cross Band Repeat function. I entered the VHF and UHF frequencies, power level and tones, selected the Cross Band mode, and was ready to go. The audio levels are preset and the audio quality reports were excellent.
Cross band repeating using a 220MHz frequency was not possible. This is more than likely a precaution due to the minimal frequency separation.
The control head has a large 5″ LCD with your choice of background colors. Options include White-Blue, Sky-Blue, Marine-Blue, Green, Yellow-Green, Orange, Amber, and White. The brightness and contrast are also menu selectable.
Unless you are only entering a few channels, I would recommend the optional PC05 programming cable. The UV-50X3 uses the CHIRP programming software.
Scanning in the VFO mode allowed me to scan either the VHF, 220MHz, or UHF band. In the Channel mode, the scan would select any channel in the list regardless of band.
There are radios that draw less power whose power cables use thinner wire, lower value fuses, and can be plugged into accessory plugs. Do NOT use these cables, even though they may be plug compatible. The 50X3 draws twice the current, and will blow the fuses and possibly overheat the wire.
The cable on the 50X3 appears to match that of the hi-power Yaesu, Icom, Kenwood series. ONLY use the proper cable for the radio.
Base Station Operation
For mobile drive testing, I teamed this radio with a Nagoya Tri-Band TB320A and SB-35 NMO mag mount and the results were excellent.
Some of the added advantages to the US market are the FCC Part 90 certification, local US support, and exclusive program support using CHIRP software. The radio can also be shipped worldwide by contacting BTech directly.
This is definitely one of the nicest mobile transceivers I’ve used; and yes, I’ve owned the “big 3”.
