Hi All, Ok, I know I've said this before, but I am now _really_ getting ready to upgrade my K2 (#402). Honestly, I don’t know how it could be better, but others have said so. My K2 acquitted itself in the last Foxhunt, and I haven't had a lick of trouble with this thing in, what, 5 years, I guess.
So besides ordering all the mods, I am now trying to determine whether the KDSP2 can really help me. My only experience with audio DSP was an MFJ 784B and I can honestly say that after many hours of testing it, that when using it, it never got me a contact that I could have gotten without it. But this analysis was done with a KNWD TS-850 with a 270 Hz IF filter. The TS-850 filtering was so inferior to the K2 that I sold it. Understand that when I used the 784B and the TS-850, it was for in-the-mud QRP signals in the early days of the QRP Foxhunts. The very worst workable weak QRM'd 40 meter signals imaginable. So maybe a DSP works better with stronger signals but then I wouldn't need a DSP. So if I am looking for help for improving intelligibility for these kind of contacts, perhaps DSP noise reduction might not be that effective, but what about narrowing the bandwidth? I typically use the K2 at 100 Hz wide setting which seems to be a good approximately 175 Hz wide filter to me, much better than the 270 Hz on the TS-850. But if the signals were in the mud (at about the noise level), would it help me copy more characters? Would the KAF2 be just as effective? Or since I like the rig, should I just do the A to B revision mods for now? Eventually I hope to get the 100 W tuner and amp in the separate enclosure, and do some traffic handling work (and Heaven forbid - actually use a microphone). The KDSP2 might actually help with this. Any advice is appreciated. Confused in Corpus Christi, Steve Pituch, W2MY -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
