1. [TenTec] Why Ethernet? (score: 1)
Author: nq5t@attbi.com (Grant Youngman)
Date: Sun Jun 1 23:07:15 2003
I don't think anyone would argue that Ethernet is the right technology for networking computers and servers. There are quite of few of these products (E'net to RS232) on the market, e.g., from Lucent

Fair at best. This is partly my business -- and there are many times when I simply have to abandon my IP voice connection over VPN over internet to the head office and pick up the phone. In conferen

That's all the standalone interface boxes do .. is give you a Telnet thingy to connect to. Doesn't take much of an engine to manage that. I suspect the box, connectors and power supply cost more tha

5. [TenTec] Some Observations on Orion Stability/Calibration (score: 1)
Author: nq5t@attbi.com (Grant Youngman)

Thought this might be of some interest. I've recalibrated my Orion, and in the process learned a thing or two about how the (or at least my) TCXO drifts over time. I originally followed the usual pra

Yes, that's all true. I wasn't interested in NIST traceability -- just getting WWV to zero at something other than 9999.970 Hz, which is where it started out. And that started because I noticed that

(Not sure why the apparent presumption that the I didn't know the difference.) The time required to reach thermal stability (of the TCXO) is longer than one might expect from the "let the radio warm

Author: nq5t@attbi.com (Grant Youngman)
Date: Sat Jun 7 15:06:47 2003
Yes, I see that too. I have to admit, I'd never turned the RF gain all the way down before :-) 40M and below, the noise level seems to plateau -- drops to a point and then doesn't drop any further.

I was mislead in my initial assessment because I wan't watching to ensure the selected mode, etc. was the same in all bands. There does seem to be a slight increase in background noise when the RF g

I'm not sure what the source of that slight increase in background noise level is with the RF gain all the way down. It sounds to me like a gain increase somewhere else in the system. But internal r

I've noticed that as well, so it appears to be "normal". Sent a note to T-T about it the other day. It may be that the code block that drives the S-meter gets the bits after NR processing in DSP, wh

Depends on where the noise is. Cooling will affect thermal noise (kT) sources. It will have no effect on quantization noise, which is a physical property of truncated Nyquist D/A conversion. The D/A

FWIW .. You may find you need to do the following to get the 60M band to come up properly when you press "0": After you load the firmware and do a master reset, "0" may bring up 80M (3.500 Mhz) rathe

I tend to the side of not getting all puckered up about these things. T-T has 60M coverage in the radio, so you can go listen (not much there). The "0" band selector issue will get fixed. I don't kn
