Q1) Can I also use SW-33plus on base radio like icom ic2300h? A1) It can use on sw33,but not include adator. Q2) SW-33 plus check the antenna and swr is 19. I rechecked other antennas and it's provided dummy load, 19. A2) Please make sure that the radio that you are checking is analog ? check sw33 use dummy load is 1.0 ,mean the meter is normal Q3) SW-33 plus good to measure mobile Radio? A3) For mobile Radio, we suggest using SW102 Q4) is it possible to test vehicular radios (power less than 100W) or just portable radios? In case yes, do you need a dedicated Load compatible to that power, correct? A4) Can test vehicle radio , but need to replace the adapter, high power dummy load Q5) Easy to use, results indeterminate The device was very easy to use. The results were anything but usual. I used a buddies swr meter and it was more accurate than this one i purchased. For my setup my buddies meter read swr of 1.75, this meter read of 3. It fluctuated up to a swr of 12. A5) Each radio will have some tuning errors. An SWR reading error of 1.25, plus or minus 1.5, is normal. If tested with a 50ohm dummy load, the reading is 1.0:1 - 1.05:1. Q6) I've read, "doesn't work with DMR radios" & that it "doesn't work in DMR mode". Simple question, Does it work with a DMR radio in set to FM mode? A6) SW-33 MarkII not support DMR radio Q7) HT VHF analog power out with dummy load and with antenna appears to match radio vendor specifications, although I do not have an in-line commercial watt meter to validate. However, on UHF analog (435.000MHz) the device displays an all white (pixelated) screen. See photo. This is consistent across multiple radios, power (3, 5, 10 watts) with native antenna or with the dummy load. Results in an inability to measure UHF power, vswr, and requires the device to be powered off and back on to recover. A7) remove the back cover, unplug the battery, and then plug it back in. Resetting the battery will resolve the blank screen issue.
