Maybe noise is the difference. I live out in the country and in very quiet radio location. 73, Carl Moreschi N4PY Franklinton, NC -- Original Message -- From: "Ulrich Hilsinger" <dh0ghu@dh0ghu.de> To
The Orion S meter never goes below S1 period. The Orion firmware uses S1 as the base S meter value and will not let the S meter go below this. I find the RX340 S meter will show some signal strength
I used to run a Timewave DSP-599zx with mine. It worked very well and solved all the selectivity problems. You just have to use an isolation transformer to drive the outboard DSP unit because neither
The Timewave 599zx has a frequency range of 50 to 5000 hertz and works very well. But it sells for $400. Carl Moreschi N4PY Franklinton, NC -- Original Message -- From: <N0KHQ@aol.com> To: <tentec@co
No, I never have any problems with RF in the shack at all. My antennas are located 300 feet from the house. I run a hard line cable underground from the house to the antenna control box. I relay swit
The 300 hertz bandwidth is measured between the 6 db down points. This is the normal method of measuring filter bandwidth. It is not unusual to hear signals down 40 to 60 db from this point. That is
They are in trouble with lack of funding. Anyone who uses eham frequently and likes it should support it. I small donation of even $15 done by enough hams will go a long way to keeping this great ham
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:
