Subject: [PVRC] Response from Ten Tec (W4PA) to PVRC Omni-7 Radio Thread


PVRCers,

I've been following the interesting that that came as a result of my 
posting regarding the new Ten Tec Omni-7 radio, and forwarded it to 
Scott Robbins at Ten Tec. With his permission, I'm posting his comments 
and responses here. If you'd like to contact him directly, his email 
address is: sales at tentec.com . For the benefit of the PVRC community, I 
ask that you post your comments to Scott and, if he allows it, his 
responses here.

Thanks!

"The funny thing about keeping this radio quiet is that word had 
actually leaked out about it some time ago but the description was so 
vague that the word didn't circulate.  There were a number of people 
outside Ten-Tec that we had also told (on purpose) that we were working 
on a new rig but it was too far away to even speculate on and that 
seemed to keep the noise level down.

"Omni-7 doesn't share hardware heritage with other rigs - unique design 
from ground up.  Triple conversion receiver but I don't know the exact 
IF's - it looks like this though:

"VHF IF > 455 kHz > DSP IF.

"Firmware doesn't share much in common with Orion or Jupiter either - it 
was written from scratch with a small amount borrowed from Orion II.

"The plug-and-play Ethernet is beyond anything used for amateur radio 
remote previously.  We're using UDP protocol which is much faster than 
TCP/IP (do a Google search on "UDP protocol" if you're not familiar with 
this).  Full transceive on CW is no problem - I've already been using it 
remoted over the Internet on 20m CW.  The issue with transceive CW at 
the moment is not the radio or the GUI - it's physically implementing a 
paddle on a radio that isn't in front of you!  At the moment the GUI 
will allow you to "straight key" the left mouse button, and will allow 
keyboard CW transmit as well.  I kluged up a mouse with a 1/8" phono 
jack and plugged an external keyer into the mouse - voila, paddle and 
keyer on remoted CW.  This is ultimately not the solution, I think, and 
we're working on some kind of keyer/paddle interface for remote 
operation now.   What this will consist of, I don't know, and I don't 
know if it will be ready at the time the rig is released for sale.

"No subreceiver.   Receiver performance (I'm estimating this...) around 
the range of the Omni-6 but not quite at the level of the Orion II.  We 
will put out RX numbers on our web site in the next couple of weeks.
