21. Re: [TenTec] 100 Hz DSP CW filter response with Orion I V2.056 (score: 1)

Sinisa, Thanks for this data. Among other things, it confirms that "100 Hz" BW isn't exactly knife-edge filtering -- as you'd expect from 199 taps and 14 kHz IF, I suppose. A number that might also b

Now we are getting somewhere! In the April QST, someone at the FCC is quoted as saying that hams are communicators first and radio operators second. In other words, you don't always need the radio pa

Besides, the DSP workload happens in the DSP (Sharc) processors, not the Dragonball control processor. So, fancy filtering, NR, etc. should not impact the user control response, at least to first ord

Lin, To clarify my earlier post, the processing delay of the DSP does not exactly indicate the amount of "work" the DSP has to do (although it is related). An N-tap filter has to wait N sample times

Hello, I am a "long time" Orion owner and follower of things related to SDRs. Lately, I've started to monitor the FlexRadio discussion lists relating to the SDR1000. At first glance, the SDR open sou

Dan, I said it, and I meant it: it's not a troll. The two products are different, as you note, and they are aimed at different kinds of users/hams for different applications. I doubt that there are v

It's not only a matter of electrical degrees. There are at least two other reasons to keep spacing moderate at any frequency: 1. The more spread out the lines are, the more susceptible they are to co

I would be really interested to know what TT's regression (and beta) testing involves. Odd that one of the primary (?) operating modes stops working and they don't notice. Maybe it's my imagination,

Circulating air will reduce the temperature rise and the total warmup drift (and maybe prolong your rig's life), but you will still have drift from changes in ambient temperature. The "better" way is

The Orion 1/2 gives you 1 Hz setting precision, so 10 Hz is easy to measure. This is very handy if you actually want to measure frequencies to high accuracy/precision. See my 2005 ARRL FMT result for

I checked in once. Good news, bad news. Good: the Orion can pull weak ham sigs out from between the broadcasters. Bad: It's still hard to get through on 100W -- no fun on the East Coast! Why can't th

A lot of the V1 firmware distributions sure seemed like "betas", but now TT is being more forthright. Lots of software products these days never seem to make it out of beta status. :-) I am intereste

Chuck, The SP is really strange in this firmware release. The SP seems to work by ramping up the audio gain until whatever audio you have (background noise etc) starts to fully modulate the rig to 10

Schematics are not published yet for the Orion II, are they? I don't see them. In any case, the same clock oscillator seems to be used for the Master and Sub CODEC in the Orion 1. I have not noticed

I don't think I've seen an "inherent flaw" in v2. From all that has been said, v2 has a much better technical base than v1 did. (Of course, you can still run v1 forever if you want.) And v2 has to wo

Software performance (stability, bugs, etc.) is not easy to capture in lab tests, or even in casual operating. (Too many modes) Traditional RF specs are a lot easier to check. Look & feel, personalit

John, You have a point. Despite the drift, my old TS-520S was quite successful running PSK31 after warmup. That's about as demanding a mode as any on HF. So why worry about a few Hz on the Orion? Sta
