All bull aside, the difference from 27.2050 to 27.2053 will be hardly noticeable, and will probably only make your OCD senses tingle because the frequency counter isn't dead on..
I for one never trust a built in freq counter/display. As long as it's close, it's good enough.. Even on Amateur Radio our freqs don't always hold 100% dead on where they are "Supposed" to be, and some deviation is normal.
Is there such a thing as too many radios??
Transceivers, receivers, and SDR! Oh My!
