Hi.

I am using RemoteRig to remotely control a TS-480SAT in my summer house near Geysir about 100 km away from my home QTH near Reykjavik. Antenna is a EFHW 80-10.  Works very well, and I love to be able to enjoy little QRM in the rural area.  (In addition I have an IC-7300 at my home QTH, but local ORM is bothering me).

I have connected the Speaker output of the RRC 1258 MkII via SignaLink USB sound card (spkr or aux input) to my PC where I have a MRP40 Morse Decoder.  This works well, except for the fact that the level from the Speaker connector varies with the volume control.

I know that I can also use the AUX/MIC connector on the RRC if I add a speaker jumper wire inside the box, but it seems according what I have read that the signal level is also variable.

Now the question: Is it possible to get a constant level audio signal from the Control RRC?  (For example approx. standard line level or similar).

Regards

Hi

Remoterig only transfer the audio, if variable audio is connected to the Radio-RRC, variable Audio will be ouput from the Control-RRC. If you use a TS-480 you have the second audio channel free so if there is a fixed level output from the radio it can be transferred through the second channel.

I have never used a Signallink, so I don't know what inputs/outputs are available.  At my remote station, I use a regular USB soundcard and run the Remote rig audio thru that for RTTY decoding.  For all modes, I plug my phones into the USB soundcard output, and adjust the soundcard volume control to control the audio volume of the rx signal.  I then set my audio level from the RR unit to a good one for decoding and leave it there.  The soundcard provides the variable audio I need for normal operations, and the RR unit is now putting out a constant audio signal.

Hi Mike and Dennis.

Thank you very much for the answer. I will take a look at the second channel method.

Using the Signalink with the variable output from TS-480/Remoterig is not a big deal however. The Signalink has a convenient volume control on the front so it is easy to compensate there for the variable output.

I hope the use of the CW decoder is only provisional. I have recently returned to the hobby after about 30 years inactivity, so my CW is not as good as it should be. I received my license in 1964, and even used TF3OM/SM7 1969-1971 while studying in Lund (Civ.ing. @LTH). 

Remoterig is a great product :-)

Thanks again
