Greetings, I recently performed the following mods on my Omni VI/Option 1: - replaced the original crystal oven on the Logic Board with a Ten-Tec supplied TXCO - replaced the BFO crystals on the TX A
Greetings, I have an Omni VI/Option 1, #11A10614 that I am trying to align after replacing the crystal oven with a Ten-Tec-supplied TXCO and ICM-supplied 5 ppm thermally-stable BFO crystals (Y1 and Y
Thanks to those who contacted me off-list... the information was very helpful. I have learned (from Ten-Tec) that the 9.0033 Mhz crystal and padding capacitor WAS factory installed and was a factory
Yes, but you must use the correct trimmer caps. The proper Omni VI BFO alignment (TX Audio Board #81597 Rev. F and earlier) is as follows: - You will need an ACCURATE high-resolution frequency counte
Well, I've gotten LSB and USB aligned. CW is proving to be a bear. The original padding cap had a value of 56pF. That allowed me to get the freq down to 9.001900 Hz (needs to be 9.000400 Hz). I added
I found the problem. Turns out that there is a capacitance spec to the BFO crystals. The original order that Dave Hammond placed was for 32pF crystals, however ICM suggested that perhaps these have a
My limited experience with Ten-Tec has shown them to be very good at product (and customer) service. However, the quality of technical information is dependent upon the person you reach (as it is wit
Re wider filters and SSB quality... I have listened to SSB on my Drake R8A with 4 kHz and 6 kHz filters. Sure, SSB sounds 'nicer' with a wider filter but this affects aesthetics more than readability

First, note that these opinions are mine, and based upon my experiences and research. I will always defer to someone who is more knowledgeable. Re cascading identical bandwidth filters without using
I agree that using WWV to align the TXCO/crystal oven (VI+/VI) is faster and better than using a frequency counter, but.... The original post I replied to was from a ham who had dinked with his BFO t
I for one would like to thank Dave Hammond for his posts. The symptoms he describes are exactly what I have encountered, and his conclusions to its causes are logical. I have gone back thru the archi
Whether or not I own a Jupiter, or whether or not I own a Ten-Tec radio at all, is totally irrelevant to this discussion. I, as an owner of Ten-Tec equipment and a potential owner of new equipment, r
I guess I started the 'pay for updates' idea on this list... and I still stand by it. I can understand why Ten-Tec gives away updates... it is a selling/marketing feature. Buy a radio and know that i
I think this is a great reflector. I mostly lurk (except when I feel I can contribute something), and I like reading about antennas, Ten-Tec history, other peoples' operating experiences, technical q
I thought that an Omni VI Opt 3 was a VI with a new 9Mhz board (VI+), new parts (buttons, black button bezel from the VI+) to support the extra 9Mhz slot, and the VI+ DSP. The Opt1 was just the VI+ D
Greetings, I'm sure that many of you have read the article on frequency calibration in the latest QST. I decided to verify the calibration of my two main rigs (Omni VI, Elecraft K2) to WWV and see ho
As someone who spent many years designing, developing, and successfully releasing commercial software that has brought in maybe half a billion dollars in revenue while I was there, seems to me the pr
[Note: A correspondent informed me that Ten-Tec's firmware is now outsourced to a company called RFSquared... so while I am using "Ten-Tec" in this post, RFSquared should certainly be getting the hea
I for one would like to see Ten-Tec go to a subscription base for their software upgrades. Purchasers would get one year of free upgrades, after which they could pay a nominal annual fee ($25 or ther
