I have 2 bird meters. One has a aftermarket PEP. The second is a true bird 43P. The true 43P shows 2 or 3 more watts than the add on kit. I am talking Diawa showing about 20W less power. On my 100W radio. I also compaired it to a LP100A. And it was also unacceptable. I will end up sending it back for recalibration. I love the size of the meter and ease of seeing the SWR at a glance. But I must say a bit disappointing.
Sorry Nomad. I am home recovering and some of the things I type do not make much sense. I did end up buying the LP100A new. I really like the bird better for many reasons. The bird and LP are similar in wattage's and sometimes they take turns showing lower and higher wattage. Never very different from each other. What I meant by saying I compared to the LP100A and not being acceptable was Diawa was way off in PEP. VS. the LP100A average was also dead on pith the LP.
No Love both Birds. Diawa will have to go back. The one bird with the aftermarket kit may be showing a few less watts because I do have the needle falling back quicker than the factory 43P. Birds are older in fact my oldest one is a old military version that is as old as me.We were both made in 1958. Works perfect. Meter that is .
