Rumlog and Microkeyer II, Can't make the PTT work

[WB0KWJ]

I need assistance with using the Microham Microkeyer II with RUMLogNG and apps such as WSJT-X and iDigi.

CAT control using DXLab Commander Works, but audio does not. Specifically, either the transmitter does not key or it is locked on. I can find no combination of settings that does not either fail to work for transmit or simply locks the transmit PTT on. For instance, if the Auto PTT is selected and the Microham Codec is simply selected as the input in the digital app, the transmitter keys without there being a transmit command sent.

Because CAT command works, but audio does not, I am using the Microkeyer II for CAT and keyer functions, but a Tigertronics interface for the audio. It works well. However, I am trying to reduce the number of devices on my desk. This should work with the Microkeyer.

If anyone knows the correct settings to make the audio and PTT work on the Microkeyer II with RUMLOG, I would greatly appreciate it. I have been having this problem for years, even with previous versions of RUMLOG.

Thank you.

Auto PTT will not work. This is a limitation in macOS.
The MKII is a very complex device, offers a lot of options.

First we have to know your hardware setup:

• Which radio?
• Audio routing?
• PTT routing?

Then you have to configure the MKII for digital modes according to your PTT and audio routings.
You should show us all relevant settings in:

• WSJT-X (Audio, Radio, Reporting)
• RUMlog (TX1/2, µHAM, UDP)
• MKII

Thank you for the response.

I was unaware that the auto PTT would not work in Mac OS. I presumed it was just an audio level detector in the Microham II hardware: it hears the digital audio from the app and keys a PTT relay, as with SignalLink and other devices. Indeed, audio PTT on the Microkeyer II works when the Microham Codec is not selected as the input, but is selected only as the output. The audio PTT only fails to work when the Microham Codec is added as the input line.

Computer: M1 Mac with Tahoe 26.5. I have the same problem on Intel Macs as well.
Radio: Kenwood TS-2000
Apps: Idigi and WSJT-X
Audio: Microham Codec selected in app's audio preferences.
PTT Routing: I have found no combination of settings to work. I have been using the automatic PTT in SignalLink.

Settings:

Audio: Microham Codecs selected in Input and Output fields in WSJT-X and IDIGI
UDP reporting in Idigi: enabled for "broadcast" and auto log upload on 2237.
UPD reporting in WSJT-X: Server: 127.0.0.1:2237 Loopback_1 Multicast TTL 1 Accept UDP requests; Notify on UDP request; accepted UDP request restores window.
CAT: DXLab Commander on 7374
RUMLOG: For PTT use Microham

All this works correctly if I use the SignalLink for the audio.

Hopefully this helps. All this works correctly if I use the SignalLink for the audio. i can even get reports for the log from other computer on the LAN.

Thank you.

All the microkeyer settings are missing.
Do you want to use the Mic input in the radio or a data jack in the rear panel for audio?
Which PTT input do you want to use? You have to configure the microKeyer to do that!

Tom:

Thank you for the reply.

Those were already set as indicated.

Type: TS-2000
ICOM Address: 0x01
Voice/Digital: According to ARRL...
Checkboxes: All combinations change nothing.

The issue remains. If I set only the Microham Codec to the output, I can get normal transmission. As soon as I set the input to Microham Codec, the PTT keys--even if I have the output to another Codec. This is the same in any digital app. As soon as I select the Microham Codec, the PTT keys (unless I have all the PTT boxes off). If I have all the PTT boxes off in the Microham settings, Then it receives via the codec, but will not key the transmitter. Everything works as it should with other interfaces.

I appreciate all your attention to this.

I would appreciate when you read the information from the link above and show us a screenshot of your MKII settings. I think you don't know that the MKII is not a simple interface. It is a complex device that requires proper configuration.

Tom:

Thank you for the response. I understand very well that the Microkeyer II is an especially sophisticated device with many configuration options and that it does not operate at the USB protocol level as do simpler audio/vox interfaces such as SignalLink. The behavior of locking up the PTT when the audio input is accessed is not typical, and I was unable to find a way around it. My history with computers includes writing in 8080A machine code in the 1980s and teaching Allen-Bradley programmable logic controllers in assembly and ladder logic for industrial operations.

I appreciate that you have created a configuration app for the Microkeyer II. I am perfectly happy to accept that I have missed a critical setting. My goal is to simply use a Kenwood TS-2000 with the MicroKeyer II using its audio interface. I have already made the CAT control and Keyer work as they should.

I have attached what I think are the relevant screenshots you want. I have limited this to idigi, as the behavior in it is exactly the same as in WSJT-X. The interface will accept only a few at time, so I will put them in separate messages.

Thank you again for your time. If this is too much support to ask for, that is OK.

Tom:

Here are the rest of the files, compressed. This interface will not allow sending them all at once.

Thank you again.

I'm wondering how iDigi can establish a dx-lab-suite commander CAT connection to RUMlog. In iDigi you have set the control port to 7374 and in RUMlog to 2237.
Watch the Network Status Window. When iDigi connects to RL, you will get a message.
