Re: Virtual Audio Cable update?

Not frequency....  it's the bandwidth of the virtual sound card/cable.

One needs the 192khz bandwidth to carry a Broadcast FM signal wide enough to facilitate RDS decoding.

What does a higher frequency give you? 48khz compared with 192 khz.

Thanks for your response. If you could add a link or two regarding the tcxo mod, that would be great.

it is good enough for all bands above 70 megs ... up to 6 gig

can be used also to transmit digital tv ... can be usd also via ethernet (with a network dongle added)

is open source so you can write your own firmware

BUT

to make the frequency real stable for ssb you need to replace the tcxo (or feed external reference in)

its ok for the price but a bit of modding is needed to make it a real good sdr (add 20 to 30 bucks extra cost and a rainy weekend hi hi)

so ... can i recommend it??? YESSSSS!!!! (since over a year on qo100 with the pluto)

I would guess that the newest version is the best to use with Windows 10. I use 4.62 on Windows 10 for the last few months just fine, but I have never tried 192KC sample rate. I find that it's best to use the same sample rate from start to finish along your audio chain, and his help text confirms this finding.

hello simon, first of all congratulations for the great work and development of the console v3.
Last week in the vhf contest, I had some very strong signals at nearby frequencies, and I would like to know if you would be so kind as to add smaller bandwidths, such as 50kmz and 100khz to increase the performance and selectivity of the RSP1A.
Define "bandwidth". I know that sounds funny but it depends where in the SDR signal chain you're referring to. IF bandwidth can be set as narrow as you want. But I think the real problem is LO phase noise in the front end of the RSP1a. I noticed it's much worse than my Airspy Mini @ VHF & UHF. At 20 kHz separation & 15 kHz BW I only get about 40 dB of dynamic range, IOW if there's a signal 40 dB or more stronger than the one I want to hear, it gets covered by the phase noise. The phase noise does go down with frequency up to a certain point (low to mid-VHF IIRC), so you could build a downconverter using a clean LO source, or simply buy an SDR with lower LO phase noise.

External Radio "Port Busy" TS-2000

 

Using RSP1A and TS-2000 (TS2K).

External Radio worked for months to control the Kenwood on transmit, now will not.

See screenshot showing "Tracking" and "Port Busy" indications.  I assume the latter is a form of error message.

Thanks to all.

Hello Piotr,

Did you ever get any information from Simon about this, and if so, could I please get it as well?   I've inquired a couple of times of Simon, but no reply as yet.

Thank you.

Would it be possible to tap into the currently processed IQ sample stream? Say, get it via TCP or some other network connection.
This would allow processing in an external demodulator, or data decoder. For example, I would use it for DAB MUX capture.

I have a rather old version that I bought some years ago, but I find that on this Windows 10 PC, for some reason, I can't get cables to work when set to 192Khz bandwidth. Fine on 48Khz.

I could do with updating my copy to see if it fixes the issue, but I've been on the website and I cant seem to find a way to do with with a paid-for version. I see no point in forking out again inless I know it fixes the issue.

That is a virtual serial port emulator.

The reason I need 192khz is I believe, (thanks to Charles G3WDG) I have found a slightly dirty way to pipe Console into RDS Spy.. basically, you use the Skimmer output (set to 192Khz) to feed IQ data into SDR Sharp via its sound card input, then use SDR# MPX output to feed RDS Spy. I am certain this will work as I do have one working 192khz virtual cable (VB cable Hifi version) but need to get VAC working properly.

It'll work well all the way down to 70Mhz, just needs a little tweak.
It's pretty well documented, just needs an environment variable adding to Uboot.

Re: Recording audio of all VFOs in matrix view ! #bug

If you're only interested in recording audio, you can use an external audio recorder program, like Audacity, that records anything you hear from the speaker output.
