It all depends on what you are doing. I find it very irritating to hear people continue to call while the DX station is transmitting because they can't hear while they are transmitting. For rag chewi
Make sure you have the FTDI chipset. Carl Moreschi N4PY 121 Little Bell Dr. Hays, NC 28635 www.n4py.com _______________________________________________ TenTec mailing list TenTec@contesting.com http:
Set the power output to zero and use the cw key line connected to the other radio's amp key line. Carl Moreschi N4PY 121 Little Bell Dr. Hays, NC 28635 www.n4py.com __________________________________
Make sure you have the very latest firmware from tentec. Carl Moreschi N4PY 121 Little Bell Dr. Hays, NC 28635 www.n4py.com _______________________________________________ TenTec mailing list TenTec@
I would certainly think it can be done. I thought the DSP speech processor in the Orion was very good and maybe even as good as the 715. Especially the one in Version 1 firmware. Carl Moreschi N4PY 1
There is no ALC feedback connection from the amplifier to the Orion. The Orion does its own ALC based on holding whatever power output it is set for. Carl Moreschi N4PY 121 Little Bell Dr. Hays, NC 2
Nice pics. Disconnecting from those bulkhead connections in the house is the best place for lightning protection. The only thing different I would have done is have the bulkhead connectors all connec
It's all done in firmware. My software provides this but it's only for the program S meter. Carl Moreschi N4PY 121 Little Bell Dr. Hays, NC 28635 www.n4py.com ________________________________________
If you run the N4PY Orion software, the display in the N4PY software will read the correct operating frequency. Carl Moreschi N4PY 121 Little Bell Dr. Hays, NC 28635 www.n4py.com ____________________
The reason open wire line has less loss is that the dielectrics for true open wire line is air. And this reduces feedline losses for high SWR's substantially. Carl Moreschi N4PY 121 Little Bell Dr. H
Loss due to dielectric loss tangent (tan) can be very important. This term is proportional to frequency, so the higher you go, the more likely it will dominate overall loss (metal loss is only propor
Here is some data taken from the ARRL handbook on losses for various transmission lines at 14 mhz per 100 feet. RG-58 hard dielectric 1.8 DB RG-58 foam dielectric 1.5 DB These two have the same I squ
I just have one final comment on this. Even though the feedline losses at HF are all mostly from I squared R loss, it just happens to turn out for other technical reasons that the more lossy the diel
What's wrong with another Balun at the vertical. There would then be two baluns - one at each end of the open wire line. Carl Moreschi N4PY 121 Little Bell Dr. Hays, NC 28635 www.n4py.com ___________
I would use the Omni A-D original series. I had a series B and the only significant change was the addition of the crystal filter slots. Carl Moreschi N4PY 121 Little Bell Dr. Hays, NC 28635 www.n4py
I have just put on my website at www.n4py.com version 3.03 of my N4PY Orion control program. This version has full support for the Orion and Orion II version 3 firmware including remembering the SAF
Just on note on using the 9 mhz IF output on the rx366 with N4PY software. I have not added any direct code for the rx366 9 mhz IF output. But it should work fine if the rx366 tracks the main receive

You realize when you do this you are essentially turning AGC off and running manual AGC. That's the way we ran the old radios in the 50's and the way I used to run my Collins 75A1. I like to think th
