And once you get into the VHF/UHF spectrum you must also consider that the overall RX system's noise figure limit can in some cases be determined by feed line losses alone. That is a situation that i
Try down loading it by "right clicking" on the download link on RFSquared.com and the do a "Save Target As..." of the OrionUpdate.exe firmware update file to a simple directory path such as C:\FLASH
I went through a similar experience, I started building my VHF SSB/CW station with an Icom IC-290H back in 1983. Used that radio for years. I then upgraded to a pair of IC-820H's to cover 144 & 432
The IF's of the Jupiter are 45Mhz, 455Khz, and 12Khz (maybe 14Khz). While it may be possible to adapt the SM-220 to one of those IF's the gotcha is that the 1st LO tunes in 2.5Khz steps. So the pan d
They exist today, they are called PC "monitors", .... and work pretty darn good too! - :). Duane N9DG __________________________________ Do you Yahoo!? Yahoo! Mail SpamGuard - Read only the mail you
The IF gain pot is easy to spot and is labeled "IF gain". But I forget which side of the radio it is on, it is easy to spot once the cover is removed though. To really be able to set it correctly/acc
Hopefully it means that there is a Pegasus II in the works, you know the one with the 24-bit A to D plus 32-bit DSP of the Orion and Ethernet interfacing. Additionally with 2 or so optional narrow ro
Actually I'm currently running 4 separate sessions of N4PY software for the Pegasus on the same computer along with WriteLog. WriteLog itself is setup for 4 radios, it tracks both the frequency and m
My interpretation is that the added cost of the Orion makes the money that was spent on big antennas that much more effective. What was implied as I see it is that the radios heretofore couldn't full
Yes the point about the Orion?s performance being driven by superior analog design is completely true. However the bigger mistake the manufacturers (and many end users) are all making is insisting th
I couldn't agree more. By going the API route TT could continue to focus on what they know best, and that is great analog RF design, and also making that bridge between the analog and digital worlds.
As I recall the last digit of the "newer" (post ~1990) Ten Tec S/N scheme tells you the year of manufacture. The "04" I'm not 100% sure of but I believe is the month of the year it was manufactured,
I feel this is key to keeping ham radio alive and relevant in the future. We as hams cannot afford to not embrace PC technology and tight computer integration with our radios. Like Mark's students I
But yet you hear of many who have Jupiters that they run most of the time in Pegasus emulation mode. They simply have a radio that allows them to do either, nothing wrong with that. I may not be an o
And this also plays a critical role in lightning protection as well. That same ground loop that causes you all those pesky problems in a RF field of few hundred to 1500 watts can be disastrous during
For those who want to play with latest 32 bit version of the Ten Tec Pegasus control program it is now posted on RFSpuared. I've only fiddled with it for a little while but it looks like the random f
Yes there is, the Pegasus/Jupiter/RX320/RX350/516/Orion sub RX all suffer the same malady as all other radio designs do that use up conversion and wide roofing filters do. That is they are prone to l
It's not so much up conversion in and of itself but the side efects of the reason(s) RX designers choose to up convert in the first place. One of the main the reasons to up convert is to provide cont
Using Spectran is part of the correct approach for determining the effects of the infamous IF gain tweak. However using the 12kHz IF signal as the test point does not tell the whole story. The signal
While on HF it is not a very hard or terribly expensive to do full QSK at high power on VHF/UHF/SHF it is simply not an option in most cases. The last thing you can afford to do is replace VERY expen
