The oscillator in the Orion for the serial port that causes it run to run at 57600 baud may have drifted off frequency just enough to cause an error when lots of data is being sent to it. I do rememb
I would think the caps might be a better one to try. The max232 area sounds like the problem. Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 27549 www.n4py.com 73, Barry N1EU I recall 2 issues with m
Really, as long as you get FTDI USB to serial converters, they work fine. I have not had one problem with them in years. I do all my software development on a 3.5 ghz 8 core PC with 16 gig of memory.
Vic, My N4PY Pegasus Plus program can do full control on the Omni VII remotely with full internet audio. It also has a nice way to link into FLDIGI to give FLDIGI control for digital modes. It will s

The 80 meter problem of going to 1.0000 mhz sounds like the 80 meter band crystal may need to be reseated. The other problem sound like the RIT pot is intermittent. I would move the RIT pot back and
It does not matter which one you use. I prefer CWL because then I know the pitch of a CW signal will go up when I tune up in frequency and vice versa. Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 2
There's a much easier way with no relays at all. You would end up with a spdt switch to select the receive only antenna. Inside the Eagle, you will find cable #2. This cable carries the receive signa
It's not an issue at all as long as the receive antenna and transmit antenna are not too close to each other. I have several radios here that do this exact thing. But it all comes down to antenna sep
The Omni VII does not ground its receive only antenna connection either. But it does have a spark gap to protect from high voltages. So the addition of a spark gap on the receive only line would be a
It's a Russian radio. It's a direct sampling radio like the Flex 6000 series but it has it's own computer built inside. You can even add a keyboard, mouse and big display like a desktop computer if y
The best USB to serial converters use the FTDI chipset. Those are the one to get. I use an 8 port FTDI and it works very well and gives me 8 serial ports. Carl Moreschi N4PY 58 Hogwood Rd Louisburg,
You need a jumper between TXOUT and TXEN to be able to transmit. Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 27549 www.n4py.com When I looked at it on the table where it was placed it looked like
There are situations in digital modes where PBT may need to move a lot. If you were using AFSK on RTTY and wanted to use a 500 hertz filter, you would move PBT a lot from center. Having the extra amo
The battery backed up RAM in the Omni V does not use the battery. It uses a RAM chip with a built in internal battery that cannot be changed. These chips were made many years ago with 10 year life li
It's not the main cpu chip or EPROM. It would be called "battery backed up RAM". I don't have schematics anymore so I can't be more specific on this. In all fairness, back at the time this was being
It's not the EPROM chip. There's no burning. It's a RAM chip with a built in battery. Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 27549 www.n4py.com Clayton N4EV Have you tried calling Ten-Tec for
No, not that one. This is a RAM chip, not the microprocessor with built in EPROM. Carl Moreschi N4PY 58 Hogwood Rd Louisburg, NC 27549 www.n4py.com Barry N1EU It's not the EPROM chip. There's no burn
If the internal RAM battery fails, all the Omni V memories will be lost at power down. For the Omni V.9, this means you would lose remembering the band stacking register values when you power off. As
I will get back home on Feb 22 and I will test it out then to see if I can reproduce your results. But does this happen if you don't use the frequency scale slider and instead use the band buttons to
