I could get: Daiwa All Mode Active Filter AK606K , Datong FL1 and a Datong FL3, all in good condition!
All three in one 'packet' for 160 european coins
My Question,anybody get some experience with this stuff?
Good DX!
First off, I'll say that I've never touched those, but I do work for a DSP company. Won't say the name as I don't want to come off as trying to sell - Amateur radio isn't our market & I don't want to come off like that.
Having said that, DSP processing is much tighter than anything analog in terms of EQ's. I can create notch filters at 48db per active using IIR filters or even more with FIR. Tighter than a nun's.. um, well, you know. At *any* frequency that I want. Analog can be good in certain bands, but aren't really configurable & have good bandpass cutoffs. Our processors are made for live sound/studio applications, but I've been using mine on my HF rig as well for just that. On top of it, I also do all my mic processing (ALC, Compression & EQ (I have a crappy mic)) in the same box. I'm sure that something like this has been developed for Amateur radio as well. Just something to consider.
