Jens,

Don’t know if this helps but your best option (in my opinion) is to build a custom cable that connects your amp to the ACC port in the 5105.

I have attached a picturing one of the 5105 manuals that shows the ACC pin functions. Hopefully with your amp manual you can match up the necessary wires and connectors to get the amp and radio to work together.

Please let us know what you get to work.

Cheers,
Brian

Many amps have an RF sense circuit. If your amp of choice doesn’t have that feature you could copy that circuit from some other design and have it as a small auxiliary box complete with BNC connectors and relays. Try a search under “ TR circuits for RF sensing amplifier switching” or combinations of that.

Has anydody found out how to key an external amp without the CE-19? The CE-19 is, at least for me, too bulky for portable work. PTT on the ACC port is not going to ground when keyed ?
Thanks for any suggestions.

Electret condenser microphones need a small DC bias voltage, typically in the roughly 3 to 9 volt range.? Even cell? phones have a mic bias (not switchable, though).? The mic needs it in order to work.? That would be easy to test, though - turn off the bias, and try the mic while watching the output power.? Turn it off if you mic is NOT an electret - a different type of mic could short out and damage the bias circuit (or so I've read, somewhere).

In the VOX submenu is a VOX gain setting that allows you to increase the audio

Anyone care to explain what the mic bias is used for? It's in the #8 menu

Got it working using VOX on the radio and the generic Icom setting in MMSSTV for rig control. I've got really low audio on the TX but i'm sure that's just something simple like output audio settings on the tablet or in the VOX settings in the radio.
Thanks for the input.

Didn't think of that but I'll give it a try.?

The only suggestion I can offer is to turn the VOX on in the 5105 and see if that will activate quick enough to successfully send the “start up” signal for MMSSTV.

Yes, I've got the ce-19 working with all other digital modes like ft8 and jt65call. The problem is there's no settings within MMSTV for Icom ic-7000 in perticular but there is a generic Icom option but it does nothing for rig control.?

Are you using the CAT usb cable that came with the X5105?
I've never heard of MMSTV - does it have 'rig control' built in?
Do you have "Line In" for audio switched on (in the menu system)?
With 'Line in" on, try enabling VOX.

Hi Ben,

Settings for an IC-7000 have worked for rig control in WSJTX and JS8CALL.

I am not familiar with MMSSTV, does it give you the option of choosing an IC-7000?

Also are you using the CE-19 between the radio and computer?

I'm struggling with getting MMSTV to transmit to the x5105. I've tried all the supplied setups within the MMSTV software for rig control but none seem to work with the 5105. I can receive audio from the x5105 and decode images, but no transmit.?
I'm just wondering if anyone has any suggestions to help get me up and running.

I'll try the pictures again.
These were supposed to be attached to the message about testing the GRA-1899 antenna out in my front yard.

I saw two X5105 videos on Youtube that really impressed me, got me thinking about the radio.
First I saw one by OM0ET, then one by David, M0DAD.? They were both about making QSOs while walking around - completely
portable.? The equipment was just the radio and a small CB whip used on 10 meters by OM0ET, and a telescoping fishing pole
with a loaded 1/4 wave 20 meter wire antenna by M0DAD.? Paul, OM0ET, was walking in a huge, wide-open field with a view for
miles.? David, M0DAD was walking along a seashore walkway, and also out on a pier.? Marvelous!
I tried to duplicate David's antenna and mount, but had difficulty finding materials that would work like his plastic
utility box frame.? I tried a small basket, with thin plywood stiffeners on the bottom (inside and outside), but it just
didn't work out.? Paul's antenna was easy, with a built BNC mount, for use with CB handhelds.? 10 meters didn't seem like
much of an option, and I didn't find any antennas like his anyway (at first).

After much mental mulling, I decided to try to make a custom frame.? At a local hardware and building supply chain store,
Menards, I bought a piece of aluminum angle stock, 1 in. by 1 in. by 1/16 in., and 8 feet long (they also sell a 4 ft.
piece).? After a bunch of measuring and planning, I cut 4 pieces of the angle stock, fit them around the radio and marked
where to drill a screw hole at each corner.? It was great!? EXCEPT I hadn't allowed room inside for the screw heads!? I
wanted a snug fit, but that was too small.? I was able to move pieces a small amount and drill new screw holes.? Then it
worked!? Well, I did have to cut a notch in one piece of the frame, to clear the antenna connector.

[PICTURE 11]? Going on with David's style mount, I fastened broom/mop handle clips (from Menards) onto the back of the
frame.? They do hold the fishing pole onto the radio.? And they work as "legs" to hold the radio tilted up when it's indoors
and setting on the operating table.? The whole assembly was rather unwieldy though, and I wanted better.

[PICTURE 07]? Next I found a forgotten mobile whip trunk-lip mount in the "junk box" (spelled "basement").? I cut a piece of
thin steel strip to fasten onto the antenna-end frame piece, with cleance notch for the antenna connector again.? With a
3/8-24 stud to SO-239 adapter, I can mount various mobile antennas onto the frame for the "walkie-talkie" mode qso's.? I
happened to find a thin, lightweight, hamstick-style CB whip and the X5105 ATU can match it on 10, 12 and 15 meters. (It's
white, and marked "Racer, by Avanti."? I also found a little center-loaded CB whip that's only about 20 inches tall, without
the stinger.? With some stiff steel wire added as the stinger, it works on a couple of upper bands and is a very convenient
size and weight.? [PICTURE 09] shows it with a Hustler 20 meter resonator mounted without a mast.? I do have a short mast,
about 15 inches, that I made as part of a homebrew "PAC-12" antenna, that I can add to the Hustler.? (The mast is a piece of
3/8 inch aluminum rod, from Menards, threaded 3/8-24 on the ends.)

[PICTURE 14]? But then something made me consider trying another mobile mount I had, a mirror or mast mount.? So I added two
more screw holes, in another frame piece, and it will hold a whip out from the long side of the case - what might be called
the "top" of the radio.

Now I can mount 4 different antennas on the radio, _BUT_ not all at once. But the one directly on the radio's BNC connector
has to come off in order to be able to connect the cable to the other antenna mounts.? Yes, actually all 3 could be on
there.? Just for "show off!"

You will notice in the last picture (#15) that there is a piece of blue, fleecy fabric around the radio. When I had to
expand the case by about 1/8 inch (for the screw heads), I got it slightly too large for a snug fit.? So I added the
padding, and it also helps prevent wear marks or scratches on the radio.?

This is NOT especially ergonomic, but then it's still a work in progress.? I'm hoping to get ideas for improvements from
other group members!

I don't think all the pictures (15) would fit well on this page, so I'll put them in the "Photos" section of the group's
"home" page.

Doug,

Sorry, No.
Found out about it when I tried the wrong mic !!]

Thanks!? That may be important to future readers.? An earlier thread about a problem trying to use the mic to trigger sending a preprogrammed CW message was the reason for finding the diagram. (He had a mic from a G90, as well as the X5105 mic.) And I wanted to know about the mic wiring because I want to use a computer-type headset with mic on my X5105.
?? Do you know what differences are?? That info might help us in the future.? And do you know which radio that schematic is for?

Doug,

The X5105 and G90 microhpnes are NOT interchangeable...

BTDT !!?

Thanks Doug

This page

says Radioddity offers 'authorized service' (image of certificate from Xiegu), so you could ask them about a schematic.

I have seen a "partial schematic" that shows the mic wiring and some other connections as well, but I don't know now where I found it.
It could also be for a different Xiegu model - they seem to use the same mic.
