Some SINAD tests for my portable radios

As my IFR 2945A is finally arrived, I started to do some tests as part of learning curve (more than 250 pages from the User Manual!!!).
I took two of my collection portable radios, Yaesu FT 530 and Kenwood TH 79 and did a head-to-head test versus the new TH D72.
As I suspected, the results confirmed somehow my opinnion based on pure day by day use. The "old ladies" are still a good stuff!
And the TH D72 is a good radio, also!

The tests follow the standard SINAD 12db procedure with 3 kHz deviation (60%), 1 kHz test signal, 2 V peak to peak at audio output and, for TH D72, the VHF/UHF AIP was Off.
