I just delete and clear everything on the hour every hour - more or less

David,
I agree but Simon has outvoted us:-)
The RSS feed helps. https://forum.sdr-radio.com:4499/app.php/feed
It's not perfect but you get all Forum messages sent by email, unfortunately often

Re: RX666 and RX888 as VHF receivers
I wish we would all settle on the Forum instead of hopping back and forward between IO and new Forum! It's getting time consuming and tiresome. Maybe time to close the IO

Re: RX666 and RX888 as VHF receivers
VHF (FM band) performance is quite similar to the RSPdx. 8 MHz though.

Re: RX666 and RX888 as VHF receivers
Now that SDRC supports it would like to experiment with the RX-888.
Could anyone recommend a reliable supplier?

Simon's screenshot here shows (I think I can just make it out) HF and VHF gain adjustment/slider? So hopefully has VHF coverage?

Re: RX666/888 on VLF?
It frequency range from 1 kHz to 1800 MHz. However with the current dlls available for HDSDR, minimum LO frequency is 1000 kHz for 2 MHz sampling. This means that the alias-free range starts a lot

David,
Yes, but I think it is really a bandwidth question.

Re: RX666 and RX888 as VHF receivers
David,
This is used in Airspys so it's probably not bad.

=====================================
Yes, I know, but I'm now using the Airspy Discovery which has a different architecture.

It might be easier on 17.2KHz:-)

Re: RX666 and RX888 as VHF receivers
I too am interested in VHF/UHF performance. Can someone with RX666 or 888 perhaps let us know even just a first opinion of performance, perhaps on VHF BFM 88-108 MHz, and 144MHz/432MHz?
I am assuming

I thought sure I read somewhere (now I can't find it) that the lowest receivable frequency is 100 kHz but that is not a

Re: IDE / ISA TV cards for computers...
All the SDRC supported radios are listed here:
https://www.sdr-radio.com/radios
No old TV cards supported AFAIK. Sorry to ask, but why would you want to, apart from in the name of experimentation?

Re: RX666 and RX888 as VHF receivers
From: Bob Dengler
I bought mine strictly for UHF use. With my 12 bit Airspys at full BW I'm constantly having to throttle back the gains to the point the 12 dB SINAD is ~0.4 to 0.5 uV. Decimation
