Awwwwwwww - You did not say you had an amp in the line - but alls well that ends well !!!!!! 73 Hank K7HP Well, guys, I hit some good luck. It seems the problem was not in the Orion, but rather the T
You need to get something like a Fluke with their 6KV multiplier or some other valid HV measurement - possibly the cal adjustment resistors have drifted or been diddled with. The manual shows where t
Thanks to all for the T756 number - I have a good local supplier of bulbs - buried in a little building that you would never expect to find anything. He has had every lamp I have looked for in past t
Hi Lin - Is that going to be a plug in oscillator to just be a swap out deal ? I might be interested if it is. I need to do a careful check again - have not looked at it for a couple years - but when
The headphone output IC in the OII is a stereo IC LM4811. I measured about 2.75 ohms output impedance at the headphone jack before I installed the RF filter . The RF filter in later OII's and the boa
I know of several guys who have done what was suggested and they just use the speaker output For the phones? Yep - for the phones - different strokes for different folks - they like it better that wa
Or the diodes or driver that switch the hardware NB in /out could kill normal main rx but leave signal to the sweep ??? -- Hank K7HP -- Original Message -- From: "Ron Castro" <ronc@sonic.net> To: "bi
There is apparently a LARGE difference in relays and mountings - My Centurion is quieter than the relay in my Orion II. I replaced the relay in my original Orion and made it a LOT quieter - no amount
The tape peeling and pulling back is a function of how its been treated. When its stretched to break, even Scotch 33 will pull back. Its much better to be cut with the Kleins and the last turn or two
I do not have time right now to dig out the schematic and see if this would allow an external check - but I can tell you the filter adds 24 ohms DCR in each side of the headphone output. If you want
I received my OII 11/15/06 and the headphone filter was still not installed at factory - SN 07C10266. But no matter what , I agree with Ron - get the board - they have designed it so it just a matter
I have always liked to homebrew but anymore seems like the doggone parts end up costing more than buying something off the shelf - and my junk box is msotly stuff 30 years old !!! I do have a homebre
Sorry for BW - was intended to be to Dick Williams - forgot this reflector replies to Discussion of Ten-Tec Equipment and did not alter the "to:" Hank K7HP
Another factor I have found is that if you are running BW under 300 hz or so - the NR becomes less effective on CW (there have been many threads about how the DSP NR is working and this follows those
A few other things that come to mind - 1.The audio board A15 is different - now has separate IC's for headphone and speaker. Also added a extra headphone RF filter- the IC is much worse than the old
