Review on Fumei GY561 Handheld Frequency Counter & Power Meter for Two-Way Radio – Digital Mini, 1MHz-2400MHz, 0.1W-50W by Marc Stewart
Good for reference
They are good for quick reference. PROS: - price ($39 or less) - cable allows direct connection to radio to check frequency and power - antenna for frequency CONS: - manual could use improvement - antenna does not read power Also this is good for reference the price .
- With an external antenna, it can only measure the frequency without contact
- Difficult to say
