Hi Sandy, 30 meters only.At regular intervals the rig appears to jump or chirp.This is common to both TX and RX. Perhaps it is some kind of instability?? The Omni VI uses a bunch of crystals in an os
As I recall, all I had to do to cure mine was slightly detune the 20mHz oscillator on the logic board. You can get the 30 meter oscillator locking to the reference by adjusting the inductor for the 3
The Omni VI and VI+ use regular RS-232 serial communications. If you have a regular serial port on your computer you do not need any level conversion. The pins used on the 25 pin D connector for TX d
Oh yea, I forgot about that little miniature stereo phone jack on the back. I've never used it. 73, Duane Duane Calvin, AC5AA Austin, Texas www.ac5aa.com --Original Message-- From: tentec-bounces@con
I don't understand the bit about it adding greater selectivity. It is an audio filter, which applies after the radio has completed its work. I cannot see how it would improve "selectivity" - it merel
If I want a latte, I'm going to Starbucks, not Ten-Tec. Ten Tec has new ones... uses ones... and even demo units for sale - the latte at a discount. Just a thought... Looking for a Omni VII, if you h
Hi Dennis The amp has a pair of RCA jacks for "Key In" and "Key Out." Does anyone know if it is possible to use the "TX EN" and "TX Out" keying loop in late model Tentec xcvrs to key this amp? Maybe.
I'm not overly impressed with the commonly accepted Bird meters in the ham community. I am looking for something much better, for sure. Guess I should look into this Collins Bridge 312B-4 or go to ca
Hi Allan, You are correct about much of the logic going on inside microprocessor chips in the Omni VI. Yet there is still a lot of T/R control logic going on is simple resistor/transistor/diode circu
I found a very narrow heterodyne What do you mean by "very narrow heterodyne?" Is it a single CW carrier? Why do you say it is very narrow? Is is so super pure that you can tell it has less noise aro
It does not go away; same signal strength (I'd give it about a 7 on our RST scale). I don't know how to add attenuation at the antenna; are these the step attenuators I've seen that some QRP operator
That's all very nice, BUT -- the Ten Tec 229 and 238 tuners are L- Network tuners, NOT T-Network tuners. Rather different animals, and the L is a generally better behaved one. If that was exactly tru
Bwana Bob wrote: Isn't the small inductor in an "L" network just there to cancel out stray capacitance within the network? That is correct. It IS there, so it is a Tee network, not a simple L network
There is no requirement to include a callsign in messages to this reflector, and including one does not prove that the sender of the message is really the licensee. Even so, I have been told that Fer
Hi Jim, You said, For example, my K3 drives my Hercules II to full power with only 10 watts, so if you have a Herc II, you could order the K3 without the 100W amp and tuner. I have a Hercules II and
How is it that you can get full output from your Hercules II with only 10 watts drive? Do you have another gain stage between your K3 and the standard Hercules II? Or is your Hercules II modified in
There is a connection on the back of an OmniVI that says 'mute'. My question is this: does 'mute' activate the PIN diode QSK switch?? The reason I care is so that I can use 'mute' controlled by the o
Tuning the PBT too quickly through the passband of the narrow filter is my first guess too. I don't know a lot about the Corsair, so there is a good chance I'm about to say something that applies to
From the list below you can see that Ten-Tec 6.3 MHz IF filters are models 282, 285 and 288. They are also designated by stock numbers 48053, 48054, 48074 and 48075. I there is a three numeral model
