Very Happy  Time owned: more than 12 months
I have read alot of reviews where people are comparing the accuacy of the readings with far more expensive TEST equipment. I find the accuracy of my Daiwa meters reasonably good and rock steady. I use them for what I think they were designed for. This is to glance at whilst transmitting, to show the forward power needle is in the right area and the reflected power needle dosn`t move or if it does its very little. All the accurate testing and adjusting as already been done. The readings off the little Daiwas are just a check that nothing as changed and for less than £60 in my opinion there is nothing better.

It's actually quite accurate!  Time owned: 3 to 6 months
A buddy of mine bought the Daiwa CN-103L. I had him bring it by my place so I could check it out. Surprisingly, the readings were in line with a Coaxial Dynamics (Bird Equiv) unit that another friend had previously brought over to my house. The Diamond meters I've previously had (SX-400C and SX-40C) have all read high (i.e. 72W output vs 65W actual). The Daiwa appeared to be nearly spot on.

After testing out my buddy's Daiwa I purchased a CN-103M meter. The box says CN-103L, but I've noticed it has some other improvements over meters marketed as the CN-103L.

First, it has rubber guards that slip on the sides of the unit(not sure if this was simply packaging material of if Daiwa intended for people to leave this in place when using the meter). Second, the CN-103M has an LED backlight vs. an incandecent backlight of the CN-103L.

This meter is a clear winner over the Diamond meters, which I was also happy with, due to the Daiwa's very accurate power readings, easy cross-needle SWR measurement, and nice LED backlight.

My only gripe is the 20W or 200W power scale. The 200W scale is simply too high unless an amp is being used. **** I did find that you can transmit 25W into the meter on the 20W setting - the needle simply goes a little bit higher than the 20W mark. This allows you to take advantage of the meters accuracy as most meters are rated +/- X% of *full scale*, so if a meter was +/-10% of full scale it could, in theory, be off 20W on the 200W scale. ****

Simply put, you can't go wrong with the Daiwa CN-103M SWR/Power Meter.

Useful meter  Time owned: more than 12 months
I've got two of these. One I keep in the antenna lead of my Comet multiband vertical (144/222/440 MHZ) for continuous antenna system monitoring and the other is for general purpose grab 'n' go use, like checking the antenna in the car for example. They've been treated carefully (I suspect they may not be awfully rugged) and have given consistent performance.

It's been a long time since I compared their readings to those on a service monitor, but my impression was that they weren't grossly out of cal. Since most ham measurements are relative-indication oriented, the Daiwa does OK. Since I use the CN-103 with FM rigs it doesn't matter that the passive peak-reading function is almost worthless due to its inability to accurately display peak power for SSB. (This is also true of the Daiwa CN-101L and MFJ-815B.)

Now, if Palstar would make a VHF/UHF coupler unit for its WM150M, that would make this Daiwa model irrelevant...

good value  Time owned: more than 12 months
I own 2 daiwa CN103 meters (with N-connectors) work pretty good, even the power is within 10% accuracy.
Personaly I prefer the 103 with N-connectors
But I wished they made a 5,50,200 watt scale

Okay for hobbiests  Time owned: more than 12 months
I'm on my 2nd Daiwa meter as the first had a stuck pinion on one of the meters. The replacement works fine. Compared with Bird 43 (standard meter, with standard inaccuracies!) they both agree. The 20W and 200W power settings are poor choices for most mobile operators. They should've used 5W, 50W and 500W in my opinion! The SO-239 spigots work themselves loose over time. What can you say? Its a hobbiest-grade unit!
