Are you trying to receive all these channels simultaneously? If so, you won't be able to do that. The maximum bandwidth of the Discovery for alias and image free output is 660kHz and to receive all th

Hello Jo Thanks for the interesting suggestion and I'll give it some serious thought. With regards to the USB ports, I have taken Simon's advice and fitted a StarTech.com 4 Port PCI Express USB 3.0 Ca

Hello David Many thanks for the mesh/grid suggestion, that would allow for the SDRs to be restrained by some tie/wire wraps and also act to some degree as a heatsink. 73s Tracey G5VU

Hello David That would certainly work for one/two SDRs but I will have five to "restrain", a mix of Minis, R0/R2 and Discovery. 73s Tracey G5VU

Have Itead activated their coupons or have all the coupons available gone? I've been trying to buy an R2 since 2 secs after UK midnight and keep getting a message that the coupon isn't valid Thanks Tr

OK thanks, much appreciated Regards Tracey G5VU

It would be very useful to know which time zone you are referring to when you say that it starts in a few hours on 26th November? Many thanks Tracey G5VU

I'm located in the UK and want to make up some of Everett's common mode chokes using the FT240-31 and TDK B64290L0040X830 . After looking around it seems that Mouser UK offer the best prices £4.80 for

I doubt very much that you will be seeing a wider recording bandwidth for the HF+ / Discovery. This subject has been raised before and squashed. Regards Tracey G5VU
