Hello, I upgrade my PC from Win 7 to Win 10 and also update HRD to the latest version 6.3. I am using  K3 mini connected to the 1258 for the RHR service. The 1258 is connected to the PC via USB.

The first problem is that I can not see the virtual COM ports of the RRC 1258 in HRD settings any more - for example for setting up CW RTS keying of RTTY FSK. But in the device control I see the 4 COMs of the 1258 and also the 2 COMs of the K3 mini. But in the USB port selection of HRD CW/RTTY setting some ports will be offered for the selection - like the K3 mini ports - but not the ports of the 1258. I try updateing the drivers but without any positiv result.

The second problem is as follow: After starting HRD and connect to the K3 mini with the COM port for CAT the connection will be established and the frequency will be read out once and shown in the radio panel of HRD. But if I tune on the K3 mini to another frequency the QRG on the HRD radio panel will not follow. But if I change the frequency in the radio panel of HRD the frequency at the remote station and K3 mini will be changed. But before updating to Windows 10 and HRD 6.3 the frequency readout works.

So I want to ask if anyone has the same problems. I do not know if the problem will be Windows 10, or may be the 1258 drivers. may be there is a issue with the driver compatibiliy to Windows 10? Another possibility will be that the HRD 6.3 version has a problem with Windows 10.

Hello,

I set up a K3 mini remote with a RRC-1258 MkII interface connected via a RRMINICBL cable. The K3 mini is also connected via USB to a WIndows 7 PC. The usb drivers are installed.

So I start testing with a ssb and all works fine but I want to use digimodes and so I setup Ham Radio Deluxe 6. CAT works and I can receive and decode digimode signals via the USB audio codec. The only problem is that the audio level on the usb codec connection is very low and the level depends on the position of the AF level knob on the K3 mini. I thought that the level on the usb audio codec connection is independend of the AF knob and always offering full scale level.

So I try to send psk data via the Ham radio Deluxe.  If I am transmitting I can monitor (with K3 mini monitor function) some very short chirp sound/clicks only. I see RF out signals on the Remote Ham Radio Web interface only then these short chirps/clics appear but no psk data stream.

In the Ham Radio Deluxe software I can see the generated signal in the monitor panel and I can also see the psk TX modulation in the windows audio mixer level bargraph but there is no psk data signal on the K3 TX site. I try normal USB mode or data mode A but the same problem.

I thought the problem will be usb connection and so I am using an stereo audio cable between the headphone out of the PC and the MIC in of the K3 mini but with the same result: no audio on TX site ...

So my questions are
1) why is the receiving audio level so weak and why is it not independed of the AF knob.
2) why is there no audio signal on the K3 TX site if I am using digimode/usb audio codec?

Any idea?
In checked also the jumpers inside the RRC-1258 but they seems to be OK (J1 left open all other set). In the bridge/IC socket I saw there is a resistor set as factory default instead of the wire for the connection to the microphone in port of the microphone connector. Is this correct for the K3?

Hello,

has anyone compare the quality of a audio streaming for digimodes like PSK31 from a remote location vs. a direct connection without 1258MKII's?

I am interesting in knowing more about the codec used in the 1258MKII. Some types of digimodes are very sensitiv for nonlinear distortion and so it can be happend that low level digital signals via an audio compressed link can not be decoded (depending on the codec algorithm) or only with a higher error rate. 

Would be great to here some experiences from HAMs using 1258MKII with PSK and other modes like JT65 etc.

Regards,
Peter

Hello, has anyone checked if the RRC Micro is working with Remote HAM Radio service? If so what parameters should be used in the program settings. A screen snapshot would be helpfull. I think I have to set the IP for local host 127.0.0.1 but what's about the other settings?

I am not shure if I should buy the RRC Micro because I do not know if it works with Remote HAM Radio serivce. I will use digimodes with a PC. So for me it doesn't make really sense  to work buy a RRC hardware and K3 remote and a digi mode audio interface because the PC can do all the jobs ...

So if there is any experience with RRC micro and Remote HAM Radio please let me know ...

regards
Peter
