When I bought the C50Z as a backup, one season I tried it and got clearer reception than with the EDM. No clue why and I don't have an SWR meter. LOL, I should send it to Jim as he's one of the experts on Radio. I'd check your power switch inside the EDM. It has a low and high power setting, I think high power is 500mw although (I could be wrong about that). And low power is either 10mw or 100mw. Can't remember. As for SWR it shouldn't make that much of a difference on such a low power level. I was more referring to SWR in regards to reflected power when using 7 watts on a rubber duck antenna. Having that much power going through a rubber duck would likely have a fair bit of reflected power that would heat up and cook the transmitter over time. But for anything under 3w I don't think it should matter all that much. So using a rubber duck or even a wire with an EDM or CZH-05B shouldn't matter, however it will effect how far you are able to transmit. Link to comment Share on other sites More sharing options...
