Good SWR, reasonable power meter Time Owned: 6 to 12 months.
My Daiwa CN-101L is great for SWR measurements, but it leaves a bit to be desired as a power meter. I haven't tried the lower frequencies yet, but at 145MHz the reading from the Daiwa is consistently too low, by as much as 20% depending on the power level and setting. You'd almost think that the 1.8-150MHz denotes the -3dB bandwidth rather than the usable range. I've compared the Daiwa to a Bird model 43 but I don't have any slugs for it to measure HF frequencies.

not good Time Owned: N.A.
The summary says it all.
Same problems as below.

Great Value! Time Owned: more than 12 months.
I've had my Daiwa CN-101L for over 5 years and it has never let me down. Compared it to other watt meters and have found it to be very accurate on the HF bands, both output power and SWR. I have run everything from legal limit power to QRP through it with no problems. Highly recommend this meter for the ham on a budget.

Diodes interchanged Time Owned: more than 12 months.
I have two CN101L?s, both from different brands. One?s response was extremely non-linear and it turned-out that a silicon and a germanium diode were interchanged on the PCB board. With de diodes on the proper place the meter corresponds normal. Then I calibrate both meters on 14.25 MHz on each range with a BIRD 43. The trim-pots on the board are indicated with 'L', 'M' and 'H'. The meters are now very accurate in the 80 - 15m range, they can match the BIRD. The deflection of the needle is about 10% less on 10 and 160m.
Frits, PAØFRI.

Junk Time Owned: 0 to 3 months.
I wish I would have read the reviews here before I bought this meter. I echo what the other people have said in that this meter reads off by as many as 30 watts sometimes.

I returned it after 7 days of this non-sense & got my money back.

a complete piece of trash Time Owned: 6 to 12 months.
I bought this meter to make power measurements for a project at work and immediately noticed problems. The response is extremely non-linear. With 15 W in, the low range reads full scale, which is correct. However, if you switch to the mid scale the needle is at zero and does not begin to register any power until about 30-40W input, at which point it jumps to life. On this (mid) scale from 30W to 60W it?s not too far off but then shoots up rapidly indicating 140W with only 80W in! I finally did a comparison test (using a Tektronics scope to measure real power into a 50 ohm load as the basis) between the Daiwa CN-101L, an MFJ 949, an MFJ 860, and a Radio Shack 21-522. The MFJ 860 and Radio Shack models were almost perfectly linear from 10W to 140W and the MFJ 949 had a few wiggles but kept basically to the line with a maximum error of about 4W. The Daiwa response on the other hand can only be described as exponential - deviating wildly from the linear response everywhere except over the 30W to 60W section of the range. This meter is a complete piece of trash. Email me if you want to see the graphs. (Tests were done at 10MHz.)

Very Poor Watt Meter Time Owned: 3 to 6 months.
I bought this Daiwa Watt meter second hand but like new condition. I expected a quality product from Daiwa but, this SWR/Watt meter is not accurate whatsoever on HF or VHF.
The indicated power output always reads lower than
actual Power output of the radio.
For the price and reputation of Daiwa I expected more. This is a poor quality SWR/Watt meter.
I believe one could get a better meter elsewhere.

Good but -not- great! Time Owned: more than 12 months.
The CN101L is -NOT- a true peak reading meter even though it has an average/peak selector awitch. It is a passive meter and does not have any active components within it as a true peak reading meter does. Furthermore in comparisons to my Yaesu YS-60 true peak reading meter the CN101L read much lower power levels with the same input even though it was switched to the so-called 'peak' function. Nowadays I have dedicted this meter to 2M use where it has the bandwidth and works quite nicely. But a true peak reading meter is is not.

Excellent Value ! Time Owned: unknown months.
This cross-needle wattmeter works from 160m to 2m in 3 ranges, 15, 150 and 1500 watts, peak or average power. All this and it costs less than $100. What else do you need ?
