Newbie questions: receiver bandwidth and port busy


John Miller K8UMF
 

Just started to evaluate SDRC and this software is very impressive and very feature rich. Anyway, I can't seem to find out how to set the receiver bandwidth except by changing modes. 

Also, the external receiver window reports 'TS-2000, Port Busy' but the SDR receiver and radiio (Kenwood TS-590S) seem to track very well together. 

Thanks in advance for any assisstance.

If I understand what you are asking, the RXR bandwidth (audio bandwidth) is in the DSP panel. The panel with frequency, audio display, IF display, then below it is the filter selections. It may be reduced in size to due to space limitations. I always turn off audio display, but leave the IF display shown so the mode and filter selection can be visible.
I think, by default (initial installation) the audio filter selection is minimized, tap on the little triangle to open it up.
See attached image.

I apologize for the crude image, but I am out of town and all I have is an iPad. I just happen to have a photo to modify for you.

Step 3 is to click on the ... icon and play, The bandwidth selection and selection set is mode dependent.

John,

Let's start with bandwidth - do you mean the receiver width, for example 2.8kHz on SSB, 8kHz on AM? If so, this is the filter width, also you can drag the filters to adjust the value.

Thank you. It is the modulation bandwidth that I needed to set.

BTW I have used HDSDR previously but your software offers many advantages . I did notice that imaging issues are much more prevalent using SDRC but I have ordered I should be receiving a new RSP1A tomorrow so this problem should be resolved and hopefully the 'Port Busy' issue. 

I was notified when I posted the question that questions should be posted to the SDRC forums. Is it OK to ask questions here?

Many thanks for your help.

OK,

I have no idea what you mean by modulation bandwidth - when using AM is this the filter width?

I mean the bandwidth required to pass the audio or other information. I understand how to set this in SDRC. 

Many thanks for the help and great software.

OK,

Any more questions just post here.

If you are worried about imaging issues on LF/MF/HF frequencies then I would steer clear of SDR Play products, particularly if you are anywhere near strong/local AM stations. They have their place as a wide band coverage device (i.e. VHF/UHF/SHF) but HF reception is most definitely not their forte. If you really have to stick with SDR Play, then better off with the RSPdx which has superior front end filtering to the RSP1A.

If you specifically need a good receiver for HF work up to 30 MHz and you are not able to consider a direct sampling receiver, then a far better choice is Airspy HF+.

If your budget can stretch a little further then even better is the direct sampling Hermes Lite 2. Yes, it's an HF transceiver (coverage up to 32 MHz), but the receive performance is stellar for the price. In fact then you can lose the TS-590S altogether and use the money saved from the TS-590S and the RSP1A to buy a small 100W LDMOS linear for the HL2. If you like using SDR Console then you won't look back. So much easier to do everything direct from within SDRC rather than trying to make loads of bits of kit track! No, you don't need to spend $3k+ on Flex radio to get exactly the same experience (better actually!).
