And that is precisely why theoretical antenna modeling programs are not good predictors of specific antenna setups. It is impossible to perfectly reproduce the specific ground conditions at an antenn
One other big difference between the rx340 and Orion is the rx340 has a fantastic sync AM mode. This really makes shortwave AM broadcast stations sound good. Also, the filters on the rx340 are sharpe
I removed the 4 khz roofing filter I previously had added to my rx340. I never really found any practical real world benefit from it. Carl Moreschi N4PY Franklinton, NC -- Original Message -- From: "
The rating is very misleading for the rx340. The DSP AGC has a 60 DB limit because of the DSP chip that was used in this receiver. The only thing that happens when closed spaced signals are in the 20
The pegasus does not write these files. These files are written by the control program running in the PC which is either my N4PY control program or tentec's pegasus control program. When you run the
Yes, they are all shortened. In the tentec keying scheme, all dits and dahs are the first one. The Orion needs to keep the keying held down for about 8 milliseconds longer when the key line is releas
No, the QSK delay has nothing to do with this. All the QSK delay does it change the time the receiver audio comes back on after transmitting. The amp relay delay time is controlled by "Ext T/R delay"
I know this is not the point you were trying to make but those unused UHF channels are now being used for local HDTV transmission. Each local channel now has several UHF channels assigned to it for H
The AMP KEY lines should come up immediately. This does not need to be user settable. This gives 20 milliseconds for the amp relays to transfer before power is applied. The delay for how long the amp
The EXT T/R delay has nothing to do with the Orion's T/R switching. It is just for external use. The Orion's antenna relay must switch on every dit and dah by design. Every tentec rig I have ever see
The Paragon can transmit anywhere from 1.7 to 30 mhz with a small mod. The Pegasus and Jupiter can also transmit anywhere between 1.7 and 30 mhz with my N4PY software. Carl Moreschi N4PY Franklinton,
Paul, I believe the radio shack usb to serial converter part # 26-183 works fine with XP. At least, that is what my users tell me. 73, Carl Moreschi N4PY Franklinton, NC -- Original Message -- From:
Version 2.13 of my software is now available. If you are a subscriber and have not received it, please send me an email. See www.n4py.com for further details. Carl Moreschi N4PY Franklinton, NC
But the Orion does do it with my Orion software. Carl Moreschi N4PY Franklinton, NC -- Original Message -- From: "Paul Henning" <paul@amtelco.com> To: <tentec@contesting.com> Sent: Wednesday, Februar
Add a 100 ohm resistor in series with the headphones. This will even out the headphone volume to the speaker volume. You can add this resistor right into the headphone plug from your headphones. Carl
This will allow you to set the sidetone volume so it will be the same on headphones as it is on the speaker by desensitizing the headphones. It also should work out to make the radio volume the same
I'm tired of hearing comparisons between the K2 and the Orion. The two radios are as different as night and day. The K2 only has one receiver, NO passband tuning, much less filter choices, and a very
No elaborate test gear needed for this test. I am right now listening to an SSB signal at 24.948 mhz. On the K2, the signal is barely discernable with the preamp off. With the preamp on, the signal j
Ok, just a quick simple test with the K2. Tuned to 28.6100 mhz with preamp off, no difference in noise with antenna connected or not. With preamp on, there is a very noticeable increase in noise with
Same test with Orion at 28.6 mhz and preamp off. Large difference in background noise with antenna connected verses not connected. The Orion has more than enough overall gain. And by the way, I am at
