Comimark 1Pcs 1 MHz -1.1GHz LED Frequency Counter Tester Measurement for Ham Radio PLJ-0802-F

Wow. Its going to FM frequency. There difference in reading between stand alone frequency counter , but FM signal is unstable no crystal calibrated FM transmitter and probably different gate timing between counters. Its works great.

Nice counter. Very wide range. Very compact. Very happy with the performance.

Told seller item was defective and was offered a 2 dollar refund. I refused the refund seller contacts me again and wants a picuture of the item for review before refund. I don't recommend the product or the seller. This is just another item for the trash bin.

added this unit to shortwave radio kit with manual tuning, shows frequency tuned with dark segments with lighted display, very easy to read. good value for price.

It works and construction looks good, but i could never get it to display the correct frequency. If I input 14.000MHz (with HP sig gen) it would display something like 14.734 and jump around, very unstable. I tried different amplitudes from 0.5Vp-p up to 5Vp-p sine wave. I also tried square waves, triangle waves, etc. I never got a stable display. Very cute device, wish it works, I need one!
