I have always found W8JI's comments and perspectives to be well reasoned and sound. I will also agree with most of what's been said in the article excerpt referenced above. What I do find troubling t
Do you mean something along the lines of this?: http://www.rfspace.com/sdr14.html It is only a RX and is only 14 bits, but it is a "no IF" approach to building a radio. These folks also have some exc
Was WriteLog generating CW via the serial Port? Or was a MK-1100 Multi-Keyer being used? The Multi-Keyer was designed do alleviate various CW timming issues when using trying to use a PC's serial por
Joe, You might want to increase the RX IF output level of the transverter slightly. Be careful though to not advance it too far. The best way to setup the DEMI transverters is to peak the noise level
We'll I'm a 40 something, and it sure appeals to me. I'm getting so tired and bored with the endless stream of unimaginative radios from all of players in the ham gear marketplace. You know, the end
Actually with a properly implemented waterfall display plus a bit of practice and understanding of what it is that you are actually seeing, can do exactly this. For instance you can see who is callin
I've been wondering where the Corsair and Corsair II fall (@ 2Khz) in that table. It's also a bit curious that the Atlas 350-XL and KW TS-820 weren't included in the list below, they have very good D
Why not make it a user setable item to both accomodate the orignal "VFO/receiver independent philosophy" design AND the more expected/traditional approach. It doesn't need to be just one or the other
Mike is correct, the Ten Etc ~18-22 amp linear power supply models that have the 2 pass transistors do have the over-voltage crowbar protection built into them from the factory. These are the 255, 26
Yes there are a number of differences beyond paint. One of the major functonal differences is that the CII has an audio filter that helps with CW ops and a built electronic keyer. Under the covers th
One method would be to listen to the fundemaental frequency of the transverter's LO xtal with the RX feeding an audio program like Spectran. Then note the precise audio frequency trace of the LO carr
Boy talk about answering a question that wasn't even asked!!! That'll teach me to respond to an email post that I only quickly scanned while in a hurry. Nevertheless the same idea presented below cou
Another part of this equation is achieving a much better situational awareness of band conditions at any given moment, spectrum scopes on the radio itself is a small step in the right direction but t
I'm not aware of any integration between N1MM and N4PY software. Though there really wouldn't be any technical reason why it couldn't be handled by the same software API level communication method as
Yes the CW bandwith 6.3MHz filters were also an option for the 580 Delta's single CW xtal filter slot. Duane N9DG __________________________________ Do you Yahoo!? Yahoo! Small Business $15K Web Desi
Actually if you look closely at the current crop of DSP IF radios they too are essentially phasing type "modulators". They all pretty much work on the principle of where the last analog IF stage feed
Amen, the notion of ground referencing mic leads is just plain silly. Duane N9DG __________________________________ Do you Yahoo!? Yahoo! Photos: High-quality 4x6 digital prints for 25¢http://photos.
Here's a technote from Rane Corporation that goes into some pretty good detail about the interconnecting of audio gear, both balanced and unbalaced. http://www.rane.com/note110.html The bottom line i
I've never understood why so many think that interfacing their radios to the DX clusters spots is such a crowning achievement of ham radio DXing and shack design. To me if the DX appears on a cluster
Part of the problem that everybody gets into when discussing lightning and our radio gear is the notion that lightning is somehow "seeking..." or "comes in on" one thing or another. Perhaps a better
