Wasn't this reviewed or one similar on The Signal Path?
Nope ... that one was about 2.5X more expensive... had a fairly solid shielding box (similar to those cheap(er) microwave components) and was a some RF conditioning (on the front end) followed by an attenuator chip, followed by a AD8317 logarithmic detector... feeding a microcontroller for ADC.
Better than what passes for a RF 'power meter' that came as an accessory for your Kenwood; but, useless (or at least not very useful) for any accurate or precise power measurements, where a broad bandwidth, and large dynamic range is required.
In the above regard... and? IMO... the one Reg has is a poorer build quality... is probably fair close to the same performance... but perhaps has more 'blinkenlites' built into the firmware/software.
By the way... if one is into "Trust, but verify" ... skepticism may wax... and enthusiasm wane.??
