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

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

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

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

In the VOX submenu is a VOX gain setting that allows you to increase the audio Brian K0FBS

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

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. Brian K0FBS -- Brian K0FBS

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

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

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

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

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. -- Doug, K8RFT

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

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

Doug, The X5105 and G90 microhpnes are NOT interchangeable... BTDT !!

Thanks Doug Tony VK2VF
