The Elecraft transverters I'm sure perform very well, they also use a 17dBm mixer like the DEMI units do. And also like the DEMI units they use a very low noise device for the RX RF amplifier stage (
Ralph, There was a posting on the VHF Contesting reflector about a year ago that had some comparisons of different transverters. The key figure that stands out in that list of transverter reviews is
Actually the Elecraft XV50, XV144, and XV222 are very much an Elecraft design and share next to nothing in direct commonality with the DEM transverters. They are however very similar in overall circu
Is it just me or does anyone else now see a huge gapping hole in the TT product lineup at the $2-2.5K price point??? N9DG __________________________________________________ Do You Yahoo!? Tired of sp
I can fully follow the logic of announcing the Orion II as was done and the reasons for the enhancements and changes made to the original Orion to get there. That is except for the 8 pin mic connecto
Ah yes, I had forgotten about the shield/mic ground issues with the current 4 pin configuration. I concur with your remarks about the balanced mic inputs. That is perhaps one of the best ideas incorp
I did. And yes it was nice to rag chew with you Bob on 144.210 SSB. The distance between us was about 600 miles. I too was only running about 150 watts. Conditions were really quite stable throughout
A fellow I work with is a modern day "gear head". In addition to the typical mechanical mods done to engines for "performance enhancement" purposes he modifies the computer programs that the engine i
It's simple. Buy or build radios that are sufficiently modular such that the pieces that do become quickly obsolete can be easily changed out and upgraded. And the pieces and parts that don't really
You might want to look at this: http://ve1alq.gotdns.com/clpd_pll/clpd_pll.htm#kits I don't know much about the details of this kit since I've only quickly scanned through the web page myself. Also d
I think so. The key is putting the modular connection interfaces of the radio at strategic points in the signal/control flow path. The SDR-1000 is clearly on the right track with its design in that r
High end in reality being only in the $150-200 range. And for undoubtedly less $'s in the future. Yepp that was kind of a bummer. But not really a big deal though, give that Audigy 2 ZS card to the
I'm pretty sure (99%) that the connectors are SMA's I've also looked at the VNA as a possible signal generator source as well. If I recall correctly it should be able to output RF to ~100 MHz @ ~0dBm
Bingo! And that's exactly why I have bought an SDR-1000... Even with its perpetual state of software flux it is already more "right" for me than anything else out there. And it's only going to get be
Depends. If your desires and needs are only for a radio that is mostly traditional in how you use it and interface with it as a user then yes the Orion will hold its "value" and practicality just fin
The "D" model adds a 12kHz IF out jack for outboard signal processing, it's generally targeted toward DRM broadcast decoders though other uses are certainly viable. The other notable change is that t
The Corsair's second IF could be loaded with filters just like the Omni V. It does only have the single 2.4kHz wide 9MHz in the first IF though. just Yes the Corsairs are audio based AGC. Looking at
a Bugs, and keyers for sending CW??? - that's *cheating*. If anyone really wants to truly claim a mastery of the CW art then they should really be using nothing but a straight key. As for computers??
Rich, I'd be suspect of a couple things: 1. Output transistors have gone bad, would be a bit surprising for a radio that was just sitting though. The main clue to look for for this type of failure is
The little bit I tried to use RF sensed keying here it drove me nuts. If you set the hang time long enough for it to not drop out between words on SSB or slow CW it would take it forever to turn arou
