Accurate and easy to use! Time Owned: more than 12 months.
I've had and used this SWR/Wattmeter for well over 15 years and must admit, it is a workhouse! I recently compared it's accuracy to a bird that was recently calibrated for 2-Way radio commercial accuracy and found it to be dead on accurate! I use it for 6 and 2 meter power and SWR readings and find it right on the nose. What more can I ask for? As Tony the Tiger says, "IT'S GREAT!" !

very friendly indicator Time Owned: more than 12 months.
DAIWA CN-801HP is a very friendly indicator, it is great for monitoring tandem transmitter - antenna, it has a large and perfectly legible meter, indicating at the same time both the falling power, reflected power and SWR. This meter is great for tuning a transmitter or antenna tuner, it has backlight and PEP power measurement works well. However, you should not expect accuracy from this measure, the declared accuracy by the manufacturer +/- 10% are fairy tales, the meter is much less accurate. Do not consider this meter as a power meter, it is simply a splendid reflectometer and a transmission monitor, I have it permanently connected to the antenna. A feature worth emphasizing is its durability, you can constantly pass through the meter 2KW power and nothing happens to it, in this respect DAIWA passed the exam.Once I bought a NISSEY meter up to 3 KW and burnt it with 1300W, actually I burned three copies of these meters, fire and smoke. DAIWA can withstand the continuous work of 2 KW without any problem.My DAIWA is a fairly early model that has such a property that when I switch the meter into PEP power measurement mode, the reflected power indicator was disconnected. I did not like it, so I made a small modification, after this modification both tips work, one from the falling power works in PEP mode, the second tip from the reflected power measurement works only in AVG mode. This is not a perfect solution, but it's better than not seeing reflected power at all.If you are looking for a precision power meter, buy a BIRD-43 and DAIWA will be better for everyday monitoring because it is better visible and more stable on the desk.I went through a long and thorny route to accurate power measurements, I bought a lot of different meters, looking for a good, accurate and also wide measurement ranges, you can read something about it using Google translatorhttp://sp5mxf.com/pomiary-mocy-w-cz/Thomassp5mxf.com

Erroneous Readings Time Owned: more than 12 months.
I have two 801HP series meters and in both cases they read within tolerance (+/- 10%) when the 12V power lead is not plugged into the unit. When the power cord is plugged into the units and the LED is lighted they read approximately 20-40% too high at 100W. To resolve the problem I wound the power cord six turns on a clip-on type ferrite bead (I think its a "C" series that fits RG213) and that brings the meter into spec.

dissapointing Time Owned: more than 12 months.
I have had this meter for a couple of years and when first received ws very inaccurate. i realigned the meter to a known good meter but found readings very non linear at various power levels. I recently tried the meter on a mates amplifier on high power and found it read ok up to 400W but as power increased the meter still read around 400W. The pros very nice meter panel but wildly inaccurate and non linear. Would not buy one again.

overall a nice meter to use.I did find that the meter read about 20 percent higher so I did a calibration against a known good meter.Power readings are a bit non linear but not a problem.SSB peak reading is great and holds well.
Such a shame that the factory gets the original calibration so wrong, must employ kids to do the job.Recalibration only took a few mins but should come better from the factory.

not bad. but not accurate as some Time Owned: more than 12 months.
I bought a new 801hp meter in nov 2016. been using it compared to my trusty yaesu ys-60,and find my older yaesu meters more accurate. the daiwa looks great and is large and bright. I use it mainly for 100 watts,but on the 2000 scale I find it way out with the amp on..ill keep it for what I use it for. would I buy another? probably not.

Great Meter for Price Time Owned: more than 12 months.
I think it is dumb for radio amateurs to rate a product by comparing it to a similar product that costs several times as much. I have had two of these meters for several years with NO problems and great results. If you hook up your meters properly and put ferrite beads on their leads, you get good results. You should use ferrite beads on your leads to all your gear. I find 5% error is no problem for amateur equipment. Are you really that exact with everything? My Lexus was not as good as my VW Beetle, but both got me there. A great meter, large dial, good lighting, great frequency coverage, PEP/Average switch and power switches. Get real when you evaluate and compare apples to apples not gold to lead.

Trash Time Owned: 0 to 3 months.
Total Trash....save your $ for another meter.I give it a #1 because she is pretty to look at but thats about it..!!!!!!!!!!!!!!!

Product has problem - Needs Redesign Time Owned: 3 to 6 months.
I also noticed a huge discrepancy between the Peak and Avg power readings; the Avg being much higher. After several tests, I discovered that the meter picks up RF on the 12 VDC input cord, detects it, and adds it to the power reading on Avg mode. Just pull the power plug out, and the Avg reading will be correct. The solution is to put .047 uf caps internally across the 12VDC line, and from each side of the line to ground. Seems to make the readings nearly identical. Bad design on Daiwa's part. I'm not impressed.

Very Poor Quality Control Time Owned: 0 to 3 months.
OK so I know it is far too easy to give a bad rating of a product with one bad experience. Mine is not that so please read if you are considering this meter. I bought one about a month ago and it worked within 10% on PEP and the hold feature worked well. However, on Average it read 90+% too hot. That is to say at 100 watts out (I run a barefoot FT950 so 100 watts is as high as it will go) on the 200 watt range setting on the Diawa 801-HP it pegs the meter at a 200+ Average watt reading.

It did this on all bands so I called up the supplier and returned it for a swap. The second one was exactly the same in that PEP worked great but Average read even higher than the first. To the tune of 250% hot. I could not even push the xcvr past 40 watts out or it would peg out in Average watts in the 200 watt range setting on the meter. Something seriously wrong here. Even a dead key was over twice the power out setting of the radio.

As a final check I called the seller and went through a test over the phone with them. I set the xcvr to 50 watts and PEP worked great at a 45-50 watt reading. Then I moved it to the 2000 watt setting, set it to Average, and did the same test at 50 watts out....drumroll...250+ watts on the scale. Moving back to PEP on 2000 watts setting showed a minor budge of the needle on the same output wattage.

Two in a row from different warehouses of the same seller. These meters have quality issues. Took me a return shipment cost and 6 weeks to confirm this for myself without any doubt. I know there will be thoughts of Average/PEP and that they are not the same...I understand the concepts both and there is no explanation for a 100 Watt max xcvr pegging out a 200 watt scale on a 200 watt setting and to push it to 300 watts on a 2000 watt setting.

This one is going back and I will not be getting another.

Excellent ! Time Owned: more than 12 months.
After spending a considerable amount of time comparing all other SWR-PWR meters available, and thinking about several of the negative comments here, I ordered this meter from Sydney over a year ago.

I have NO complaints!

The large meter is great and well worth the little bit extra compared to the small meter Daiwa. The accuracy (watts out) is exactly the same as the meter on my Elecraft K3. Running QRO with my linear amp I have no way to judge the accuracy and actually I could care less if it is in fact 10% off. I know it is reasonably accurate according to what my amp should deliver @ current and voltage readings. SWR readings are equal to that given by a MFJ-259 Analyzer.

Using the PEP setting for SSB output, there are no problems as stated by some of the reviews below; perhaps Daiwa has improved the circuit. The meter needle during SSB slowly rises and remains at peak (as it should do) and does not go up and down quickly.

The LED meter lighting certainly does not "blind" me, as another review stated.
The only problem I can think of is that I wish I would have had this meter many years ago!
