Mcbazel Surecom SF401 Plus 27Mhz-3000Mhz Radio Portable Frequency Counter Meter with CTCCSS DCS Decoder

I needed to clone a set of radios that nobody at work knew the tones or frequencies. In 15 minutes I was able to accurately reproduce all frequencies and digital tones and was then able to program a group of radios in no time. It paid for itself on it's very first use. The tones were exact. The frequencies were very close. But knowing how radio frequencies are allocated I was able to adjust the stated frequencies to the closest allocated frequency and completed the task without problem. This was a perfect choice. If I never have a need for it again I will still be very happy with this purchase.

Works as described, and is very easy to use.

It came on time, but the one i received today apparently is a used/return, it's missing the charger box also range is very weak i have to physically touch the antenna with the counters antenna to get a reading, but it appears to be pretty accurate when i finally gotten it to read, my radio said 27.1650 the counter picked up 26.1660. If the range was stronger and worked correctly I'd give 5 stars even with the missing charger block. Only 1 antenna was wrapped inside the package also.

very helpful when you dont know the operation frequency

During the last hurricane response there were two agencies arguing on what frequency they were transmitting on. Without a laptop to read their radios I was able to tell each one what frequency they were transmitting on with this little handheld. For the price this frequency counter is amazing. I have deployed to three disasters and I keep this in my go back because it always comes in handy. It tough, and seen a little abuse due to the weather but it keeps on working. Highly recommend this little hand held. I keep it in a small plastic case brought separately for travel purpose.

Scans frequency and codes in just few seconds. Accurate frequency reading but the DCS reading was different from the one programmed on the radio. Searched online and found out it's an inverted CDCSS (DPL). Looked at the chart that somebody posted online and the DCS was correct. This frequency counter is accurate, portable and not too expensive. I wish the freq counter had an option to convert the inverted CDCSS to standard code.

This Counter DID work, but after 30 minutes only a few digits would flash now and then? Only a handheld radio would display it's expected frequency, but it needed to be closer than 5 feet and that is 'dangerous power' to a Counter 'front end'! I was NOT expexting a spectrum analyzer, but Los Angeles is TEAMING with RF almost everywhere ~ except on THIS display. I thought a Factory Reset would help and the "SELLER WAS PROMPT" with a reply, but I never could get this Counter to reset or function again? The term "door-knob" comes close, but I've lost way too much time with this little piggie so back it goes!PS, For a instrument with SO many options (in the Menu), a DECENT MANUAL is a fair thing to expect and ask! Buyers, you are on your own because they don't have one.

Not for wide bandwidth. Inaccurate at 100mhz. Good at 400mhz and up to 2.8 gighz.
