I really like my Alpha 99 - very solid. However a 3-500 "instant on" amp (my old Centurion) is missed for its ability to be powered and ready to transmit in about 5 seconds vs. the 2.5 minutes requir
To understand it better, you might try measuring the reactance changes across one of the bands in question. Also, remember that as a fraction of the frequency (3500 kHz, for example) the width of the
John, You'll find a 600W amp probably does about all you want an amp to do. It makes a big difference over 100w, and is only a half S-unit weaker than max legal limit at the other end of the QSO. I l
The Alpha 89 and 87 are keyed with a different circuit using a PIN diode, where the 91B and 99 use the vacuum relay. My '99 also works FB in QSK by tying it into the keying loop. There are mixed repo
I don't think the concept was to pay for fixes, but to pay for new firmware functions. However, after some period of time, it might be reasonable to charge for ongoing "support" much like many softwa
First, try the various resets beginning with a master reset. 73, Duane. AC5AA Sent from my iPod Duane C. Help please. I have a brand new (one month old) Orion II which was working fine until this mor
Tim, As I remember it, there was a fair amount of ripple in the passband on the VI and VI+, and the Inrad mod is a couple (more?) of capacitors that were designed to help flatten that out a bit more.
Uh, isn't that what BDR (blocking dynamic range) is all about? 73, Duane Duane Calvin, AC5AA Austin, Texas www.ac5aa.com Terry, N4TZ/9 has touched on an important point that has long been a priority
While it is true that the additional amp stage reduces the dynamic range, that does not mean that in all situations a problem will be seen. I've written about this recently here. If your rx is operat
John, You are correct- the 500 Hz and 250 Hz will work great for anyone who doesn't have an S9+40 signal right next to them in the band. I wrote about this a week or two ago and got the business from
We're really wandering off the TT thread, but just to add my 2 cents - if you don't have an account at the bank you want to cash the check at, they probably won't cash it for you. Yep, that's right -
With my Orion I, I use the main RX to pull the DX station out of the mud, QRM, jammers, and cops. It's very important to hear him. The subRX is more than sufficient for listening to and placing my si
I can do the same with only the ground side of the antenna connected at the 238B antenna tuner. The Orion has a lot of gain, and often I can copy signals with nothing connected to the antenna port at
John, My Orion 1 exhibits what you describe - I have nothing connected to Ant 2, but if I switch from Ant 1 with a signal on it to Ant 2, I can still hear the signal, though faintly, from the Ant 1 i
That's how my Orion 1 works - S9 on Ant1 can just be heard with no S-meter movement with Ant 2 selected. 73, Duane Duane Calvin, AC5AA Austin, Texas www.ac5aa.com --Original Message-- From: tentec-bo
Don't completely throw away the paper - I use a scratch pad to write notes I want to remember on my next transmission (his name, QTH, etc.) But head copy is wonderful - I run mobile CW when I take lo
The "238" should match your Omni V and VI two-tone grey combination. I had one from the 1998 timeframe that matched. I can't recall if the earlier (brown) version had a different part number or not,
My Orion 1 has the same problem reported in the original posting. I have to run the AF gain at about 75% when driving my Heil ProSet, and unplugging the earphones causes the internal speaker to reall
