Front Panel Stereo Socket Board Wiring Layout
|
The front panel stereo socket board wiring layout for universal case for ubitx has been published. 8 pin relimate female to female connectors are used for digital and analogue connectors on ubitx board and the front panel board.
For mic ptt, volume, encoder, speaker TVS connectors have been used with right angle pins.The case comes now complete with these accessories too.Those that want the wire kit or complete kit with board can get from our website amateurradiokits.in Pictures for front panel board. /g/BITX20/photo/6439/7?p=Name,,,20,1,0,0 /g/BITX20/photo/6439/8?p=Name,,,20,1,0,0 use any wire but follow the wire sequence.? Kindly report if any mistake found. best of 73s Sunil? VU3SUA |

Sunil, Thanks for the update. An issue: I found on my front panel PCB that pins 2 and 5 on the headphone jack were not connected together (tip and ring), so that I only heard audio in the left side of my headset.? I jumpered those two pins together, and now I have audio in both sides.? It still properly disconnects the speaker when the headset is plugged in. Have you made an update to the front panel PCB, since I received mine (a few weeks ago)? Connector discussion: I ended up ordering and using a Dupont kit for the female bodies/sockets and right-angle pins.? They worked OK, but the volume connector hits the main PCB standoff, and the mic connector is a very tight fit against the chassis-mounted round 4-pin XLR connector body. Would the TVS connectors be lower-profile?? Suggested US source for those connectors?? Any model/order numbers? I got my Dupont kit: and Inwiss crimper tool: . from Amazon US, free two-day prime shipping. We have a group of folks here that ordered a quantity buy of uBitxes, and some have ordered and/or received cases, but I'm one of the first to actually assemble one and get it on the air.? We are having a meeting in September to address uBitx build hints and kinks, and I'm putting together a log of issues/fixes to help them get their uBitx boards up and installed in cases properly.? I thought to share my Dupont kit to anyone that needed connector shells and sockets, but if a TVS kit is better, I'll go that route.? So far, searching for TVS connectors on Amazon hasn't turned up a kit similar to the Dupont connector kit I have. There's another thread on here with my notes, in case you've not come across it, yet: Volume control connections: I figure I'm not the only person that even after doing some head-scratching trying to figure out which pins where the 'high" and "low" pins on the volume control, that I managed to get it backwards, and was rewarded with a VERY load noise when I first powered the radio on with the control turned completely CCW.? It would be helpful to have a photo of the actual back of the volume control, showing which pins are "high" and "low" ("mid" is hopefully kind of obvious). XLR Mic connections:? There is no information as to which pins on the XLR jack are to be assigned to Gnd, PTT, and Mic.? I did a Google search, and found a few which seemed to agree that Pin 1 is GND (natch), and that Pin 2 is Mic, and pin 3 is PTT.? At least that's how I wired it.? I haven't found a pre-wired 4-Pin XLR mic to try, but it appears that Cobra CB mics were wired this way, and there may be some some of industry standard for wiring 4-pin XLR PTT mics, but I haven't found it. Thank for all your effort to bring us a really nice case for the uBitx.? Mine is dark green, and sets off the green LCD display nicely. 73, -- Dave, N8SBE

If one has working MICs meant for other rigs that he uses, we can by a similar connector and wire accordingly . It helps sharing the? same mic for ubitx. regards sarma vu3zmv On Sat, Aug 4, 2018 at 8:08 AM, R. E. Klaus via Groups.Io <reklaus@...> wrote: There really is no "standard" for wiring mic connectors.

Hi Eddie,? wiring for 4 pin :? pin 1. Mic input,? pin2 PTT,pin3 is put ground and pin 4 is mic ground. So link 3and 4 to earth and pin one is mic and pin 2 is ptt makes sense to keep connections short and screen the mic lead.Hope this helps. Ian M0IDR
