Alan Many thanks. I've tried what you suggest and you're right, it does retain b/w first set by mode. I can live with that. Did you find this out by chance or is there a reference I've missed in the
Duane I think you have answered the question for yourself. Mixing primary and sub RX audio to one TU is messy and produces just that on a screen. With only one TU I would suggest you toggle between l
I'm with you Duane. In a pile up QSK is invaluable. I use QSK 100% of the time when I'm not contesting. I used to use it during contests too but use of SO2R provides greater return and is incompatibl
Well I'm really no expert and I think Ten Tec's basis for the decision to deploy roofing filters when DSP b/w is at 75% of roofing b/w would be better explained by them. Having said that, I offer the
Well...........the one thing that everyone appears to be overlooking here is PBT. If the 2400 Hz roofing filter were to switch in at 2400 Hz DSP then the PBT control would not function. Instead of ad
Bill I think this is the first time I have seen something you have written that I disagree with! Single coversion superhets are inompatible with the roofing filter concept. The filters in the K2 are
Sinisa You are correct, I am mistaken. Which, I guess, brings us back to the original question about whether switching roofing filters at DSP b/w = 75% roofing b/w is optimum or unecessarily conserva
All of that is pretty much dead on Ken until the last bit. If a receiver has an IF (Intermediate Frequency) at all, it is not direct conversion. Direct conversion converts in one step from rf to audi
Whether a filter is a roofing filter or not isn't really anything to do with where in the receive chain the filter is located or what it's performance specifications are. It is to do with the role it
Are you sure about that Rick? I'm not saying you're wrong but it's hard to imagine. Or are you refering to a loop circuit which only Ten Tec use, so far as I know. Bob, 5B4AGN
Bill I'm sorry I didn't hear you. K6VVA wasn't too good even with his kW. We're suffering with a lot of QRN on 20m currently and I guess it buried your 5W. Hopefully it'll be a bit quieter for the WA
Duane I have been running full QSK for almost 30 years. I have never used a keying loop with my amps and I don't have hot switching problems. Currently, I have two Orions, one drives an Alpha 87A and
Duane That's interesting and of course you're right there is a sort of interlock arrangement available on the FT1kMP. I'd forgotten about that and never found the need to use it. (Perhaps it's just t
Carl I guess if yours works fine that way, mine would too. Then again, it works just fine without needing the loop. Bob, 5B4AGN the of previously which with edge I WPM,
This is interesting. As I said the Omni VI+ doesn't work well in QSK with the 87A or the Acom whether loop connected or not and that's due to the way TX Out on the VI+ is timed. If the Orion really w
