General discussion forum / Re: K3 twin & audio noise
« on: 2020-01-24, 21:06:35 »
We received the Elecraft mic and still have excessive broadcast audio noise. The recommended K3 twin settings are all in use and we did verify the pcb strapping as correct and ok.  We have physically relocated the control RRC away from the power supply as well as tried it via an alternate power supply.  None of this has been successful at eliminating the noise... 

Perhaps toroids are the next thing to try?

We have been working under the assumption that the noise originates at the control end; and, while I still think that is likely, is there a quick way to insure that our assumption is correct?  Remote power source has been isolated, cabling, settings, strapping and jumpers have all been verified at the remote RRC as well...

Thanks & 73 de N5NYM

We had presumed that since the mic worked fine with the K3, that it would also work fine with K3 default settings on the RRC.  No extension cables are in use anywhere... 
We will verify the pcb strapping with a multimeter and try varying the codec settings and report back.  Hopefully, that will put us on the right track.

We have successfully set up a K3 Twin remote installation and CW is working well, as well as a remote interface to the SteppIR via RC-1216H.

Unfortunately we have a bad noise problem with SSB audio- it is much noisier than the modulated voice on xmit... And there seems to be a distinct hum in the receive audio as well.

We are using a Kenwood mic in lieu of the Elecraft unit; but, have tried JMP1 both open and closed (per the docs) to no discernible difference.  As there is a hum in the receive audio I don't think the mic setting is necessarily to blame.  Suspecting power supply issues both RRC's are connected to the switching power supplies powering the rigs so I don't think power is a problem either.  We are acquiring an Elecraft mic; but, I am not confident that will solve the problem.  All of our jumper settings have been double checked. All cabling is new and was supplied with the new RemoteRig gear. Strapping is via the K3 Twin PCB's.

I expect the solution will be a simple one; but, we are at a loss at what to try next.

Any thoughts or suggestions are welcome...

Configuration, Webswitch 1216H / SteppIR option not shown?
« on: 2020-01-16, 23:16:51 »
I am trying to set up an RC1216H with a SteppIR SDA-100 controller.
The IP configuration is set up fine on the RC1216H; but, when I navigate to the Advanced Menu, the SteppIR isn't an option I can select...
The only choices are:
 Prosistel D
 Green Heron RT-21
 Yaesu GS-32B
 AlfaSpid RAK

Further, the RC1216H indicates a software version of 4.50, which seems newer than the latest available to download, 4.27? This makes me hesitant to attempt to update the firmware.

Any thoughts greatly appreciated...

Configuration, RRC 1258 / Re: K3 twin, remote power-on

Thank you for the reply...

Well, I have verified all of the relevant settings, esp those on p215 of the manual.  Cable is attached from the rig ACC to the i/o port on the remote RRC.  When we power up the control K3 it displays "TERM" until we power up the remote K3 and then all seems well. If we turn off the control K3, both do indeed power down.  Not sure what we're missing; but, we will keep looking.

I am setting up a new K3 twin setup and just getting started with both radios in the shack and on the same LAN before moving the control setup off site.  The control K3 seems to be controlling the remote rig fine, including powering off the remote rig via the control rig's power button.  What I can't seem to do is get the control radio to power the remote rig on... I thought based on what I had read, that that was supposed to work?
Any suggestions appreciated.
Thanks & 73,
