Hi Steven I'll keep this as short as reasonable. You most likely know more about radio than I ever will. However, for what it's worth, the RSP2 annd SDRuno have been my introduction to SDR devices although I have now used others as well, together with SDR#, Console and HDSDR. For my purposes, SDRuno...

Hi Steve Had you thought of posting an image of your workspace for the benefit of the knowledgeable (not me) on here to have a look at it when up and running when under load, as I believe that it may be helpful. I've got a cobbled together, heavily modified old Dell laptop (64bit - i5 - 8mHz ram and...

Thank you for looking Mike
No, it had not be calibrated recently, nor after the event and frequencies were and remain "spot-on" after the restart.

Keeping it simple - Is this "simply" a digital audio filter?
It appears to function as one and if so why is it not mentioned in the user manual along with the other available filters as it's very useful?

If you're looking for a transmit & receive antenna this is not for you. However, for receive only, I am quite pleased with this: https://www.ebay.co.uk/itm/Scanking-HF-Discone-0-05-To-2000-MHz-Antenna-/182337955174?_trksid=p2141725.m3641.l6368 It does what is claimed, at least capable of receivi...

Having zoomed the display in and out, I observed a discrepancy between the tuned frequencies on VFO A (3413 Khz) & VFO B (3446 Khz) and those displayed and measured on the waterfall, both traces being 8 Khz lower than tuned (see image). This is probably an insignificant event (a glitch) and was ...

Thanks Andy I now have a successful Hi-Z connection to a 50 ohm feeder from a mini-whip, whilst I wait for the loop arrival. I suppose there must have been a good reason to choose that type of plug... Mr Iken appears to be inundated with orders (can't be bad for him). I do appreciate your taking the...

If I understand the following correctly, it should be possible to connect the ALA1530 interface output directly to the Hi-Z port without modification, or can someone tell me whether I am mistaken? Ports A and B are intended as general purpose RF ports, but the Hi-Z port is really intended as the pri...

Your loop project sounds really promising David; congratulations and thank you for your comments. I was, of course, aware of the two different bsd's, but was only interested in the RSP2 flavour and was familiar with the stated filter arrangements, but failed to understand why a direct link from the ...

Thank you for the guidance Andy.
Just a question though - I had always believed that the MW/FM filters on the RSP2 only apply to Ports A & B.
However (an uneducated) look at this BSD seems to indicate that they are automatically applied to the HI-Z port.
I assume that I'm probably wrong...
