The PRO-26 Wiki has a link to a review Rich Wells did on this handheld, comparing it against a BC3000 and PRO43. His biggest gripe was that the audio is a bit muffled and weak when compared against these. The EHam comments didn't really compare the scanner to anything else.
I haven't seen any other online reviews of this handheld, tho. 73s Mike
I don't have anything scientific to offer, just some hands on experience with the Pro 26 versus a Yupiteru MVT9000, and Pro 96 (extended freqs enabled via win96)
I live in Columbia SC and there is a lot of mil air activity in the area (SHAW AFB, McEntire)
I sold the 26 a couple years ago, it was a nice radio. It was a little deaf in some of the bands compared with the Yupi. but acceptable. I believe the 96 is a good bit better than the 26. Little difference between it and Yupi.
Starrsoft.com has the freq. sensitivity results for the extended freqs .
I have had alot of radios over the years, and for my practical needs these two, Yupiteru and Pro96 (lot of Dig. trunking here) do about everything I care for.The 500 channels are also a big plus. I have a vfolder for Mil Air only......its full
The PRO-26 has good sensitivity and lots of coverage. However, the audio is absolutely the worst I have ever heard in any handheld scanner. You will need an earpiece with the PRO-26 if there is any type of noise around you. There are many better scanners out there.
