what module in the IDE source file views contains CAT emulation and control? How does it key the PTT? send an active output signal to a pin that is wired to internal PTT line??

I know someone said CAT PTT is handled. (could be!)  Well, did you sniff the com port and see if the CAT PTT command was actually sent?
Quick look at the CEC code and the generic ACK '0x0' word doesn't match the FT-XXX expected response..... I still would think that PTT CAT command would have had to gone out once to test for the reply.

Re: RX #V6 quits working when ant coax braid is connected #v6

 

Hi Andy,

Looks like I got company.. similar event. Lightening struck my opposite house barbed wire wall post but dod not touch the
electrical transformer just a couple of feet away.

We saw a orange ball lightening out side my shack window.

The landline, modem, lan connected PC and even my Ac - all blown. Rigs survived!

A "lightening arrestor" to discharge the static away from a shack is a wise move.

I don't think it was a full hit of a main lightning bolt because likely that would have set fire to my residence as well.

 It took out ISP's POE internet antenna interface unit, two HDMI input ports one each in two smart TV's, two wired ethernet NIC cards in two separate PC's , and two video adapter display output ports on another two PC's (network file share server and NLE editing workstation).

My main ham PC USB onboard interfaces/hub disabling the PC entirely (had to replace it) the main LR TV satellite TV receiver, a yamaha two channel USB audio mixer, a Yaesu CAT cable and a SignalinkUSB sound device and I suspect RF input to my FT857. It took almost 6-8 months to find each of the failed components and replace them one at a time and get back to now where it is almost all, except for the possible protector block in the coax switch, to serviceable. Ham PC new one is a refurbished one about $275 Cdn, FT857 repairs $300 + shipping both ways, Yamaha mixer and Sat TV receiver were under warranty, SignalinkUSB was $175 + $75 for replacement PCB for damaged one (so I could repair it myself but didn't find out I could until after a replacement unit was paid for and shipped to me) .

I was sitting in an armchair at 3:00 AM reading when the bolt struck, and I could tell by the sound of it that likely something might be affected, but had no idea how extensive the final end effects were going to be.

Home network ethernet cables close by runs of audio and USB cables and because it was all close to the ham PC onboard USB hub and network cabling the one hit was able to be induced into so many places because of so many interconnections.

It was not apparent immediately that there was widespread damage to so many components but it did demonstrate how it's effects can be transmitted/induced in so many directions at once and being like a major static discharge any module with any CMOS components at all can be damaged and not show up for a long time.

I had worked in electronics and communications facilities for 35 yrs and never seen such widespread damage as this anywhere. Usually it was just replacing carbon protector blocks or heat coils in landline termination points and reboot a system to be back in business; no such luck in this case.

When I had the SAT TV dish and receiver installed the Bell service tech did not install a ground; I had to fight with Bell engineering management to get them to install one and even then they only put in a 40' run of #16 guage insulated hookup wire as a ground when it should have been in my opinion #6 bare copper stranded ground cable. But then who am I right?

Lightning is very weird, expensive and not a ham's friend at all.

I watched the videos this morning and received my V6 this afternoon.  So, this weekend I will have a chance to do some tinkering.

I checked the website for final stage power adjustment t on the transmitter.  I didn't find anything.  Can I use the same instructions for a V5 or V4?

uBitx v6 jacks on purchased enclosure

Larry Mittman
 

I just purchased my full kit uBitx v6, and I find a small problem. None of the plug jacks are labeled! As I have great difficulty ready the schematic, how eo I know what plugs into which jack?  This goes for both the front and rear panels.
Until this gets answered, all I have is a brick.  Please reply asap.
Thank you very much.

Hello Tim,

Yes the jam nut for the volume control is not needed for the V6 Full Kit but has been included anyway just in case one would want to change the front panel. This is a part of the standard Basic kit and we have also included it for the Full Kit that comes with an additional case as well. But its not needed.

Hope that helps.

Re: V5 not receiving local am stations

Solved!
Thanks to all who helped.
It turned out to be my manual antenna tuner not being able to tune in MW. I connected my antenna straight in to my ubitx and all those MW broadcast stations came to life.
