safe pakage speed delivery the frequency counter is nice and good accuracy HZ digits two only

حزمة آمنة سرعة التسليم عداد الترددات جميل ودقيق أرقام HZ اثنين فقط

I tested the device with my dual band FM xcvr and found the accuracy was off a few megacycles at both 2m and 70cm. Looking at the back there is a trim cap that adjusts the reference frequency for the meter. (I included a pic showing it.) I was able to tune the meter "dead nuts". (Engineering term for extremely accurate.) Can't wait to mount it in a box for a professional looking piece of test gear.

Another Great and high Quality product from BanGGood. I give it 10 stars !!! Works fine....did some tests with Tx on HF-VHF..see pictures. Recommended !!!

The frequency counter was tested from 1 MHz to over 500 MHz to see at what signal level it gave an accurate and stable reading. This was done by increasing the signal level at a know freq until the counter display was correct. Amplitude adjustment was down in 1dBm steps No measurements of maximum input power were made because of the risk of damage. The sensitivity rolls off below 10MHz.and above 500MHz. The counter stopped functioning at 580 MHz. The frequency was calibrated using a known 10MHz source. A large adjustment of the tuning capacitor was required. Testing was done with a 9V battery as the power source.

I jumped a wire from the antenna metal outside to the middle of the meter's coax connection and got a reading within 0.01 so yeah it's good! My battery was a little low too so I bet a fresher one would work better.

Nice Equipment. Easy to integrate within small inclosure. Precision is OK for hobby (see picture with gene at 100MHZ

Un bout de fil suffit comme antenne et permet de vérifier la fréquence d'émission. Excellent produit.
