KID RF Hash

[Tobit]

Vic, the KID just happens to be in REST because of a thunderstorm.  It is terribly dark here. 

[Vic]

OK,   is there any chance,   that the KID awakened,   and was producing a very small amount of power,   at the time of that pic?

If you shut off the PV input breaker,   and looked at 6M on the radio,   does the display look any different?

Thanks, Vic

[Tobit]

Vic, the KID was "resting" for a good five minutes before I flipped the breaker to shut off the battery breaker.  I did not shut off the PV breaker in either pic.

If you want to make your own 4 to 1  1 to 1 combination Balun  watch the 3 part series on TRX bench youtube . There is a lot of information packed in there - I had to watch them  a few times ! I built the combination this winter and it works well .

Larry, thanks!  I'm a lazy old goat but I will check it out.

Tobit,

It is always good practice,   to turn off the PV breaker,  before the battery breaker,   when powering down an MPPT CC,   and to turn on the battery breaker first,   then the PV breaker,  when powering up.

Some CCs can run,  just with the PV breaker on   â€¦   you still might try shutting off the PV breaker with the battery bkr on,   just to see what the radio screen looks like.

FWIW,   Vic

[Tobit]

Vic, how can I do that?  As soon as I do, the KID goes into REST because of no input?  I'm confused.

[ClassicCrazy]

yeah the Kid will stay on if you shut off the battery breaker first but the PV breaker is on and power to it.

Tobit  -  Do you have your battery negative grounded ?

Not here, KID shuts down instantly with the battery breaker off.  If I shut off the PV breaker, it goes to REST.

Not here, KID shuts down instantly with the battery breaker off.  If I shut off the PV breaker, it goes to REST.

First,   if you have some PV power available,   the KID might still operate with the battery breaker off,   just have never had the PV breaker on with the battery one off.

Second,   I was hoping that if you switched off the PV breaker,   with the battery breaker on,    that the KID would definitely be resting,   and then the view of the 7300  screen might reveal something ,   more.

Would think that the KID,   when in a normal rest,  to shut off the Buck Converter (the primary hash-maker),   and open its input relay,   and just sit there waiting for something to do.

Vic, you are right.  Attached image is the radio with the PV breaker off and KID resting.  Still some spikes but a bit better.

[Vic]

OK,   Thank,  Tobit,

SO,  now,  wonder what that screen looks like,  when you shut off the battery breaker to the KID,  with the PV breaker still off?

Thanks,   Vic

[Tobit]

Vic, I posted that earlier..

Off, both PV and KID.  Silence!

[Vic]

YES you did,   sorry Tobit,

Did not pay enough attention   â€¦   nothing on the screen,   BUT,  that's cause there is no aerial connected   â€¦   duuuuuhhhhh   on my part.

So  it looks like there is s bit of stuff from the KID when it is Resting,   probably caused by its processor,   and perhaps a power supply,   housekeeping stuff.  This may be helped by some ferrites in the DC to the radio,   KID,   or both.

More later,   thanks for your rapid response.   73   please keep in touch,   VIc   kilo six  italy charlie   ..
