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

The Surecom SF401 is an interesting device and great for basic testing field of radio communication equipment. It's a hand held frequency counter with CTCSS and DCS decoding and can handle analog and digital (DMR) radio systems. When held around 18" away from a transmitters antenna, the device will display the transmission frequency to a precision of 3 or 4 (programmable) decimal places. Although not as accurate as a lab frequency counter, it is perfect for field testing and checking the frequency and CTCSS tone of unknown transmitters. The only minor drawback of this product is the plastic case which would be much better if it was metal. (Review price £31.42)

well its a great little frequency counter its just the right size to fit in your pocket, being cheap I thought it would not be much good, but I have been proved wrong, its bang on reading the frequencies, there is one draw back you have to key up very near the counter but I am very pleased with it and save me having to spend a lot of money on one of the Hunter range which cost about £200 this will do just the same job. I would 100% recommed this product.

This works a treat, although it does take a second or two longer than my old one to display the Freq. IT would also be nice to have a few more decimal places available. The CTCSS code feature is perfect.

This is a very simple way to test the frequency that a two-way radio is transmitting on. It displays the frequency that is in use and if analogue can display the tone codes in use as well. You have to keep transmitting the radio for a while for it to pick up the tone code in use. Set it to digital and it can show the frequency being used.

I needed a unit for checking some radio packs. Unfortunately as my packs are only 50mW ERP this unit has trouble reading them unless they are plugged directly into the reader via a cable. Great for 1 watt or higher walkie talkies etc not so good for body packs and handhelds.

A handy little unit. Remember to press save if changing the number of digits (and perhaps also if altering the calibration). If you need the spectrum rather than just the frequency try: "Spectrum Analyser RF Explorer 3G Combo"

Very happy with my product it does exactly what it says I use it to find The frequencies If my radios and other things......

What is the point of a frequency counter when you have to stand right next to the origin of the frequency? This thing won't pick up a radio signal more than 18 inches away from the source, utter useless rubbish, avoid at all costs

色々な機器の電波出力や周波数を調べたくて購入してみました。 取りあえず手持ちの特小トランシーバーで確認しましたが、 周波数は約0.5秒、Ctcss.Cdcssは約3秒で表示できました。 ただこの手の商品にありがちな事ですが、 アンテナはついているものの手軽に空中線を拾える訳ではありません。 物にもよるとは思いますが送信機との距離は5cm～50cm程度がベストなようです。 送信機との距離が5cm以内になると誤表示を起こしてました。

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.

Excelente, marca perfectamente la frecuencia. Es ligero y funcional, con dos antenas con conector bnc. Pantalla en color y facil manejo.

Ho acquistato questo prodotto però non mi ha soddisfatto in quanto mi indicava frequenze casuali. Lo reso ed il venditore è stato molto corretto e mi ha subito rimborsato Ottimo venditore serio e corretto

arrivé plus tôt que prévu. Bien emballé. Fonctionne très bien. Ravi de mon achat
