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
That's an excellent price. The Pegasus is one of the most under recognized radios out there. While it is not a top end performing contesting or DX'ing mnachine it is still a very good bang for the bu
Actually the Pegasus shares much more in common with the more traditional radios out there than the ideal concept of "SDR". Yes it has updateable firmware but it is a "tradition radio" first and SDR
Not really. The review of the SDR-1000 was done with the radio incorrectly configured. This miss configuration was due to the proper instructions for its setup not being made available to the ARRL. F
Perhaps the best way to understand the RISC-like nature of the Pegasus command set is to look at the Programmers Reference Guide for the Pegasus and also the Programmers Reference Guide for the Jupit
It's relevant for sizing the RF components of that new direct DSP to RF D to A legal limit Class E amplifier based radio that Ten Tec will be building...:). Duane N9DG ______________________________
282 285 I'm not aware of the 2.4 kHz filter ever being offered as an option, so as far as I know it does not have any "28x" designation. Yupp you're right. It's the only 9MHz filter in a Corsair. My
The 580 Delta is almost in this same camp though a dual conversion design. I found its main limitation (other than poor AGC) is that the audio chain is rather noisy. Ten Tec radios of this vintage I
Actually there are two sources of hiss, one is indeed the RF/IF stages, and the other is clearly the audio chain. As an experiment turn the RF gain all the way down (with 50-ohm load or no antenna) a
Well I did some more experiments tonight and made a few relative measurements. One thing that I was able to determine is that the PBT board in the CII provides about 10-12dB gain. I also found that t
