    Anybody have one of those Nano VNA's?

    Yes even with the 3k dollar units you must calibrate after every change in a configuration of coax, baluns, connectors etc just the way it is until they come out with something even smarter.

    Anybody have one of those Nano VNA's?

    I have a Bird SiteHawk 6000 so I'm looking for a toolbox analyzer and have one of these like you just ordered to keep in my field toolbox. Here is a Man Captain that has done 5 or 6 videos on these I watch all his posts.

    trying to correct internal counter -

    If you use the clarifier and set the receiver to read 27.2045 and then transmit does it show the same as the receive setting it should? It should also show the same offset on all channels. The frequency should also show the same transmit frequency on an external counter as it shows on the Cobras...

    trying to correct internal counter -

    Does this unit have the clarifier locked for receive and transmit or does it only control the receive?

    Browning MKlll receiver

    I could be somebody's misguided attempt to control "HUM, FEEDBACK, RF FEEDBACK ???" Usually, these kinds of changes are not based on knowledge, and don't hesitate to start with a clean slate and just put it back the way the factory designed it.

    New President Lincoln 2 V3

    HUH? The only way you can ever have 3 or more radios on SSB enjoying a solid communications roundtable is if they are all capable of shifting both rec. And Tx freq. at the same time. The only thing that would not make that true would be the clarifiers somehow not done correctly.

    Mobile anybody on here run a high power (5kw+) suburban? i need some advice

    This reminds me of what my Dad said when I came home with a brand new Boss 429 He took his pipe out of his mouth he said rev that thing up again so took it up to about 4 grand and let settle down he looked at me and "WHAT THE HELL DO YOU NEED WITH THAT MUCH POWER". I said the same reason you...

    Mobile anybody on here run a high power (5kw+) suburban? i need some advice

    Maybe you are experiencing something completely different like harmonics that are rampant this would make it impossible. Are testing with just the radio or at high power Try? Try running coax direct from the radio to the antenna or use an analyzer and short length of coax and maybe you will see...
