Mcbazel Surecom SW-112HF 1.5-60MHz 120W V.S.W.R. & Power Meter

I bought the SW-112HF to measure the output of a Xiegu X6200. (I continue to have doubts about the efficacy of that radio ;-) ) I needed something more accurate than the cheapo SWR/power meter that I have for the station here. In all, it's a rather weird little collection of switches. Having an on/off switch is the weirdest part. The rest of it, the calibration switch & pot are another story, especially since it's a basic 'Stockton' meter circuit (which would work great as a cross-needle meter system). It appears to measure the output pretty correctly. The IC705 (which radio I trust does indeed crank out 10W on external power) reads as 10W on the SW-112. The X6200 reads ~7.5W out at full-tilt (8W) and the X5105 gets a bit over 5W (I trust the X5105 to be fairly accurate). A G90 gets a full 20W read at full power too. So there is a basic accuracy for ham use. As an SWR meter it works fine, once 'calibrated.' So that much is worth the crust. The instruction sheet is printed in 5pt type but at least the instructions are legible and in decent English. (Opposite side of the sheet is in Mandarin.) Even without the sheet it's a manageable meter set up. In all not a bad meter. Can't use it on the 500W radio but what the heck, at least I know how my QRP stuff is working and the accuracy of the Xiegu boxes. So five stars, considering the price.

After comparing this guy with a few other meters, I'm feeling confident that it is relatively accurate and is definitely more sensitive than 30 year old MFJ meters, and I recommend it. This is an inexpensive analog forward/reverse power and VSWR meter. It is completely analog and doesn't require any power to operate, but does accept a 5-12 volt input for the LED meter lights and includes a USB-A to barrel connector to power the lamp from a rectangular USB-A port. Note that you will need to provide your own patch cable to go from your transmitter to the back of the meter, that is not included in the box. It has 3 basic modes (Forward Watts, Reverse Watts, and VSWR reading) + a forth "calibrate SWR to max transmit power" setting where you adjust the dial while transmitting to calibrate the VSWR part of the meter. There are multiple switches you need to flip between different states to move between the modes, but there is a silkscreen set of arrows on the front that makes it relatively easy to do (if you read the 1 page manual first). Accuracy wise, it says my "100 watt" transmitter puts out 110 watts (with the dial pegged) and 10 watts (at min setting) so it is probably accurate to at least 10% [It's certainly possible that my 30 year old radio is putting a little more than 100 watts out...] An SWR reading on an antenna was close to that given by my NanoVNA. If you are really concerned with perfect accuracy, you will probably need to pay more, but this meter does a good job giving you a ballpark estimate, detect a sudden SWR spike due to a break in your antenna, test/confirm a radio at a swap meet is transmitting correctly (with a dummy load or antenna attached please!), etc. I found the white background meter perfectly legible even in dim lighting, and you really only need to plug in the lamp if you use it in the dark / at night without lights.

This meter is junk please dont purchase or you will be sorry. I received it and didnt get around to using it for a few week till I could get my radio installed. Took it out of the box and realized the needle was out of range and couldn't be zero out so I contacted seller since I couldn't just return based on time limit and the seller just Blew me off just like they will blow you off if you buy this cheap junk. I ran into another guy that bought one and his needle fell off right out of the box. Haha be careful

Worked as advertised. I connected it to my (tr)uSDX and a vertical antenna that reported an SWR of 3.8 which agreed to that reported by the (tr)uSDX. Reconnected to my Chameleon whip and it reported 1.0 which matched the (tr)uSDX and my G90. Power output on the (tr)uSDX was 4 watts which appeared to be accurate. Seems to be a very good meter especially at this price. It is replacing an SWR/Power meter that was purchased many years ago and no longer works. It is not necessary to connect power to the unit unless you are working in the dark as the meter is very easy to read. It actually came with instructions that were easy to understand. Only thing missing in the instructions was the setting needed to transmit after verifying SWR and Power.

compact and acceptable item

Compact and light weight meter. Works as advertised on my QRP radios using the 12 watt setting. I use the reflected rather than the SWR setting. When the reflected setting is at its lowest, then you KNOW the SWR is as low as it can be for the existing condition. No need to rely on calibration or the SWR circuitry. Yes, I recommend.

Awesome product works great

I was hoping this would work. But it appears it was DOA. I read the instructions several times and followed them while trying to get a power reading and a SWR reading. The power reading twitched and stayed at zero. The SWR would not even move the meter pointer when I turned the knob slowly, as they recommended, or fast; it did not matter. So, it appeared the meter was damaged, although the meter lock switch was set to off when I took the meter out of the box. It was either a bad meter or it was damaged during shipment, as the box came in just an Amazon plastic bag rather than a box. Either way, the meter was no good to me and was returned. I had considered getting a replacement, but did not want to have to return that in case a second bad item came. If I purchase another it will be a digital meter.

Nice little meter.....does the job very well at a good price. Well built

tres bon produit pour le controle des antennes HF

PERFECT !

É notório que não é novo, em virtude de o aparelho não vem com manual e o aparelho não trazer as tampas plasticas nos conectores das pl259 femeas.

Very good
