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

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
I can verify that genuine Scotch 33 applied as Jerry says will last at least 27 years in fierce AZ sun. I just took down some that had been holding coax for that period of time and the layer just un
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
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 _______________________________________________ TenTec mailing lis
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 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
Yep - for the phones - different strokes for different folks - they like it better that way - and other than losing the stereo or main sub separation it works just fine , and covers the "slurp/echo
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
Any of you Centurion gurus know offhand what PN the 4 meter lamps are in the Centurion , like to have some in hand before I open it up. Hank K7HP _______________________________________________ TenTe
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

Was playing with trying to record the Orion 566 audio output using the "LINE OUTPUT" fed into my laptop LINE IN (or microphone input too ). Tried all 3 level settings for line out - and tried setting
FWIW - I just put LEDs in a T2X controller internally lit meter - with diffused LEDS - don't like it very well.Played a lot with current and sanding them more etc. I see that All Electronics . www.al
