Hi, sorry for the delay, the wait is justified.
Attached to this email I send to you a short survey about the OEM vs Real limits of some of the Commercial Kenwoods radios. (VHF and UHF).
In past days I asked some of my ham fellow to pass by my home and borrow his radios for a few minutes; the test was to put a 0.5 Mhz jumps in the channels of the radios and check where they fail to look the PLL VCOs, sure I tested them on either mode (RX o TX) data shows that RX will go about -6% in the lower edge and is the first to fail in the upper edge with a mean of a +4.0% (in one case TX can work up to 8%!)
In short: either VHF or UHF models can tolerate safely a -4% and + 4% as a rule of thumb (working on both RX & TX), data from my experiments shows that in most cases this is safe.
As -4.0% is the minimum that will allow to work the ham bands either on VHF as in UHF I will set a +/- 4% on both edges.
So, I'm submitting patched to the 3 drivers that support the tested Commercial Kenwood radios, I will create a new issue explaining the situation and data found and will send the 3 independent patches against this issue, I will link the Tom's issue as a subset of this.
This will allow to use that radios in Ham bands and yet the OEM ident/model string in the settings area will show the real OEM values, just as Tom suggested.
