I'm a new subscriber to this discussion list. Bought my first Ten-Tec rig a few days ago-- an unmodified Omni VI. It is unquestionably the best radio I've ever used. I'm looking for the 221 filter (2
For a great all-purpose audio filter, the MFJ-784B tunable DSP filter is hard to beat. This one can be tuned for very narrow (down to 30 Hz) bandwidths, which can be centered around your favorite CW
This is second message sent-- don'y know why my earlier message last night does not appear in the archives I've completed installing the CW model in my Omni VI (not VI+). I've got it setup to kick in
"Is there any compensation for the insertion loss of the filter?" Yes, the filter board includes a transistor amplifier; however the roofing filter is only a four-pole configuration (and fairly wide
I've completed installing the CW model in my Omni VI (not VI+). I've got it setup to kick in along with an Inrad 753 400 Hz CW filter whenever the NAR switch is engaged. The roofing filter is designe
The "non plus" Omni VI has only one NAR filter switch, which can be either on or off, so options are limited. I have my Inrad roofing filter hooked up so that it is switched in along with my downstre
I'm offering $100.00 plus postage for anyone willing to part with this filter (no longer available from Ten Tec). Again, that's the Ten Tec 221 for 9 Mhz IF in Omni VI, 250 Hz bandwidth and 500 Hz of

Chas, I've been interested in this also. Found this web-site, which may be helpful: http://www.hal-pc.org/~kg5u/301.html 73, Chuck NI0C _______________________________________________ TenTec mailing
W4ZV quoted George at Inrad as follows: "Note also that a 4 pole, 600 Hz filter centered on 9000.7 will pass just about all of the energy getting through your special 250 Hz filter." This is true; ho
George, This is really great news. I'll post it on the Ten Tec Reflector-- put me down as one wanting an Omni VI CW roofing filter with 500 Hz offset (and 600 Hz BW). Are there nine others out there
Ron and Roger, I sent an e-mail to INRAD asking if I should place an order for the special 500 Hz offset CW roofing filter. Georgia replied and said go ahead, just be sure to specify the 500 Hz offse
Clark & Roger, The pre-production CW roofing filter from INRAD (and presumably the standard one they are offering) has an offset of 700 Hz, not 750 Hz, so the mismatch is not quite as bad. Probably t
"In Ten-Tec Omni VI the BFO frequency is fixed, for any given mode, using crystal oscillators. So for a narrow filter with a specific center frequency, only a specific narrow range of audio tones wil

I recently acquired the coveted 221 filter from a nice ham who had one unused still in the box from Ten Tec. I installed it in my Omni VI, Opt. 1 with CW roofing filter mod from INRAD. It was a big d

Here's at least a crude data point for those interested in performance of the Ten Tec Omni VI with new INRAD roofing filter: Perhaps this "real-world" data will be of interest to those who have inqui
A couple of weeks ago, Ken Brown, N6KB, asked: "Can you discern any difference in the noise blanker function with/without the Inrad roofing filter? For instance when band conditions are such that you
