SURECOM SW-33 Plus SWR / Power -ICOM-52 Testing

[@RidgeHikerAdventures]

Great review and test. I just watched your video to see one in action before I placed my order. Looks like just what I want for the portability and price. 73s from Northern Nevada!

Glad I could help,73

You dont need to turn if off for "reset" It will do it automatic the moment it senses as new burst. Quite nice it keeps the value. you can also save configaration, on how you want the screen to figure.. you do that by holding in the button, then it will remember the orientation for next time.

Thanks loads

Thank you for the positive review. I'm curious, would this equipment be suitable for testing both my 25-watt and 45-watt base radios, or is it designed specifically for portable radios? Your clarification would be greatly appreciated. Thanks!

[@HamTechRadioScannerDrones]

I think 45 watt sounds high i would carefully read the manual .

Didn't you read the manual ?

@@Cris-ih3jx why read manual when there are many helpful people in KZbin,

I have this Swr meter and I like it. But my main concern is when the replacement battery time arrives. Do you have any idea how to replace the battery and what kind battery is it use ?

[@HamTechRadioScannerDrones]

Ooh time to dismantle

[@malcwallace4119]

The power the meter can handle is up to 120 watt not 5. The dummy load can handle 10watts

[@HamTechRadioScannerDrones]

Ok

[@terryshrives8322]

Every single person i have seen uses this swr meter completly wrong and because of it get gross miscalculations.

[@HamTechRadioScannerDrones]

Please explain.

@@HamTechRadioScannerDrones Did you read the manual? It shows _PICTURES_ with big red Xs and green check marks of incorrect and correct ways to test. Power is done with radio vertical position with dummy load NOT antenna . SWR is done with radio vertical and finger tips gripping the meter. This may or may not be an updated manual, but it does seem that everyone is just doing what _they_ think is correct.

[@Techy125]

Finger tips act as a counterpoise for antenna. Vertical and touch the sides, then check SWR 😊

[@theripper121]

@@braddahbill8131 I noticed this as well. While testing SWR you need a hand on the unit or you will get wild miscalculations. But the instructions quite clearly state how it SHOULD be used.

_@braddahbill8131 & @Techy125_ -- Excellent comments. However, the antenna of a handheld is not just grounded (counterpoised) by the user's hand, the proximity of the user's head is important, too. That's why, when manufacturers measure the power on their handhelds, they position them next to a dummy head. So, to do a proper measurement you not only hold the radio in your hand, you must also move you face close to it the same as you would if you were going to talk into its built-in microphone. SWR measurements are a little different and you MUST carefully follow the photos in the manual. This is because accurate SWR measurements require you to also ground the test instrument (SW-33 Plus). So, when making an SWR measurement, you must hold the radio in one hand, hold the SW-33 Plus in the other hand, and move the radio near your face. When you are NOT concerned about the SWR and just want to know the power, then you do not need to touch the SW-33 Plus.
