[email protected] #35773 is it possible to connect Kenwood PTT mic which am using for TM281 to bitx / ubitx ? Is possible kindly tell me how to connect it .. DE Vimal
N8DAH Member Profile All Messages By This Member #35788 You would need an RG45 case mount female connector and would also have to wire it for ptt/mic etc in the case. Just me but I wouldn't use it for the bitx.
John McFadden #35792 I'm using a Baofeng on my bitx40, I need a different option on my ubitx as the two independent jacks (3.5 and 2.5mm, a precise distance apart) sharing wires between mic, speaker, and PTT is making soldering a gigantic pain.? Single panel mount RG45s are available in female to female, or buy a female to male, cut off the connector and you have 1' leads to play with for $6?on Prime. The female to male mount from inside the case, usually sold for Ethernet applications.? The $20?"quality" Baofeng mic and two $8?jacks vs $35?Kenwood mic and $6?Ethernet jack, I hope the Kenwood is a viable option.?

Absolutely. My plan is to use the same headset/mic combo that I use with my computer for video conferencing. If you wanted a very lightweight solution, you could wire up a TRRS socket and use earbuds with a built-in microphone like those that come with many cell phones. -Neil N0FN

Gordon Gibby #35806 开云体育 ?Arvo:? ?every mic is different but there are common themes.? ?Lots of mics these days use electret elements which require a load resistor and DC voltage (the Bitx has a resistor and DC source) --- but you'd be wise to LOOK at the schematic of your chosen mic and ascertain how it is built, what it wants, what the internal technology is (electret, crystal, ceramic, dynamic, internal transistor amplifier, etc) ---? ? On my Bitx? I specificaly provided dc-coupled output to run the standard electret mic, and then used a small electrolytic capacitor (a few uf) to DC isolate to allow a powered CB-style mic to also be used.? ? And because I do some digital, I put a wall-mount 8-pin RJ45 female there to which the mic or the soundcard system can connect (and there you need the DC isolation because the soundcard output is a TRANSFORMER and will drag the bitx input DC way to ground.? ? )?? That's ham radio -- look at the circuitry, try to figure it out the best you can, give it a whirl and see if your understanding is correct!!?
