Re: [Flexradio] FlexRadio Digest, Vol 30, Issue 21

Rob, Let me confirm Roland's statement that the DC hump has nothing to do with the SDR-1000 and everything to do with the sound card. Better cards have lower DC offset and/or noise. The FLEX-5000 does not have this hump because it uses a built in high performance A/D converter (i.e. no hump). Ja

Re: [Flexradio] Receive Equalizer

Tim, How do you do that, ie, save EQ profiles? Actually, the receive bandpass is perfectly flat using DIGU with the receive equalizer "reset" to zero. It's just that on SSB, you need to use it, and it is active on DIGU receive. Transmit is where you really need an equalizer. I measured the

Re: [Flexradio] Buffer / Sample Rate

I agree ... my best preformance is 512/192 .. but it runs fine at 256/192 ..now this is a Intel dual/6700 with 4 Gigs..and the only item on the machine is the 5000A. John: I upgraded SVN today and see that there are now Buffers for TX & RX ..explain the merits...?? Also I sweep the the headpho

Re: [Flexradio] Receive Equalizer

Chas, I agree that the RX EQ setting should be saved, but save it along with the TX EQ settings in the TX Profiles. That way you can associate a TX profile with a particular operating mode rather than being restricted to just one RX EQ setting for a particular mode of operation. I have several T

[Flexradio] Receive Equalizer

Hi, I have been using the receive equalizer to reduce some of the high frequency audio noise on the SDR-1000 which is particularity annoying when using NR. The audio noise is a problem only on voice modes such as SSB. However, when I use digital modes, the audio bandwidth is greater than for

[Flexradio] Buffer / Sample Rate

I hear some people are using 192k sampling rate with 256k buffering. Are they doing this in "safe mode 1" or in the "normal mode"? I am running an Intel duel processor 2.4 with 4 gigs of memory with the two high speed 7200 rpm western digital hard drives in a Raid 0 configuration using XP for
