It's a nice new "skin", long overdue. Some good content has been added, too. One frustration -- The "rfsquared" firmware site is still not easy to find unless you know about it. On most websites, if

Yes, but it's obviously not where I was looking. A good web site is not about gotcha, it's about anticipating how different users are trying to navigate. Firmware updates appear under "other Ten-Tec

David, The Ten-Tec web site we've been talking about is the company's own site, www.tentec.com, with product specs and on-line store. This mailing list is for open discussion, mostly among TT users,

The only reason, seems to me, is that on 240 V, you will draw half the current, and you will experience less voltage droop and I2R power loss. This may give you a little extra power on peaks and a li

Funny -- up here in the blue states, we're billed by the kilowatt-hour. 10 amps at 240 V cost the same as 20 amps at 120 V. I don't think they're smart enough to charge for unbalanced current in the

What would you do with faster DSP parts? You could increase the 3rd IF passband or provide more exotic filtering. I'm not sure it would make a big difference for most people. Providing a dedicated DS

Design is a lot easier if you can guarantee the processor always has scheduling headroom, enough RAM, etc. Speed is no substitute for correct logic, of course. 73, Martin AA6E

I have to agree that Orion's stock roofing filters are 100% adequate for me, and I bet for most other ops. The only time when a 600 Hz filter would help you over a 1000 Hz stock filter is when there

I bet you have an alarm system or other phone device that has a panic (call 911) function. RF is getting in and triggering this function. No way your ham gear can dial 911 by itself! 73 Martin AA6E

Mark, The meter is driven by a D-to-A converter from the Orion CPU, so it's displaying whatever value the computer wants. Hopefully it has something to do with actual power, but you don't know! Also,

I can repeat this in CW mode, especially when adjusting for moderate power, around 50 W. The Orion power meter fluctuates by up to 10% a few times per second. The good news is that the actual output
