FlexRadio Comparison Chart

Mike-VA3MW

Hi All

I have been playing with a building a FlexRadio comparison chart. It is a bit of an eye strain, but if you can see it full size, it does show all the models and all the features.

Interesting, it shows the 510 and 520 non-M radios available 2025 Q4 . And the 510M and 520M available 2025 Q1. Is this a typo? Should it show that the 510M and 520M as 2026 Q1? If so, does that mean that it has already been determined that the M versions of the 510 and 520 won't be available until sometime in the first three months of 2026? I was told when I prepaid for the 520M I pre-ordered, that it should ship sometime in the last three months of 2025. ( 2025 Q4 from the original information I was given) So, what has changed that the M versions have been moved to next year? And why haven't buyers who have prepaid in full, been notified instead of finding it out on a chart?

It was a typo.

Thanks Mike, that's what I was hoping to hear. Have a good night.

I am actually working on this chart everyday. I will replace it as I make changes, hence the reason for the data stamp.

I appreciate you posting this . I think a lot of people would love to have a chart like this one to actually be able to see what the different models provide. This even helps people buying used Flex radios. While most Flex owners already know this, you might think about adding what kind of storage media ( SD card or eMMC ) that is used with each model and whether or not it user replaceable. I can think of a few more things as well. But, it could cause information overload!

That is why I did it. We also have a lot of staff who have joined over the more recent years and are have not worked with every radio.

The 6700 entry does not include VHF.

As an aside I noticed that on the second Nyquest zone (2M) the wideband noise suppression seems to ADD very weak signals (From the first Nyquest zone?)

The FLEX-6700 does cover VHF from 135-167Mhz as an exciter and then there is an add on amplifier.

Thanks for putting this together. I’m considering a FlexRadio as my next purchase and this is super helpful.
