Smallest bandwidth Aaronia V6eco and Reuter SDR

[FrankMichael]

First of all, I would like to express my sincere thanks to Simon Brown for making SDR Console available for both the Reuter SDR and the Aaronia SPECTRAN V6 ECO.

Both receivers are still relatively uncommon among radio enthusiasts, which makes your support for these devices all the more valuable. I am particularly grateful for this because the Reuter receiver does not have its own dedicated SDR software, while Aaronia's software, although extremely powerful, can be rather complex and overwhelming for many hobby users.

I have one suggestion regarding the selectable bandwidth/sample-rate options when starting these receivers in SDR Console.

At present, the smallest bandwidth I can select with the V6 ECO is approximately 7.625 MHz, while with the Reuter the minimum is approximately 1.25 MHz. For many applications, especially HF listening, such wide bandwidths are simply not necessary and can place a considerable load on the computer.

Would it perhaps be possible to add some additional, smaller bandwidth/sample-rate options for these two receivers?

It would be particularly useful to have options going down towards approximately 250 kHz, if this is technically possible with the respective hardware and APIs.

For many SWL and utility monitoring applications, a bandwidth of a few hundred kHz would be more than sufficient. It could significantly reduce the processing load while still providing more than enough spectrum for normal listening and monitoring.

I fully appreciate that this may depend on what the Reuter and Aaronia APIs/SDKs actually allow, but I wanted to raise it as a possible enhancement.

Once again, many thanks, Simon, for supporting these rather specialised receivers in SDR Console. It is greatly appreciated.

Hi,

I'll think about this, but processing a 7.625 MHz bandwidth does not use a lot of CPU. If you see a high load maybe take a screenshot.

Hi Simon,

thanks. My point is also that I sometimes want to record an IQ file at the same time and analyse the recording in parallel with programs such as Black Cat Systems’ Vacuum Cleaner.

In that situation, my 11th-generation Intel Core i9 already has quite a bit of work to do, even if I am not recording the full available bandwidth but only a relatively narrow section of it.

Best regards,
Frank
