Yes and no. After trying MANY MANY headphones, I settled on a 300 ohm RACAL/Astrolite aviation headset, 300 ohm Telephonics TDH-39 audiometer/aviation phones, and good old 300 ohm Western Electric AN
That's a pity. The Orion has the finest audio I've every heard from an hf rig. Whatever those TT engineers did in the design stage, they NAILED the audio. Sadly, I'm still working my way up to an Ori
You may want to read Rob Sherwood's web site on receiver and rig testing, about excess audio response. He reports operators get tired listening to any audio above the voice or SSB, needed frequencies
If the PSU is next to the radio on the left side of the rig, you will probably get some hum in your audio. One of the little quirks of TT life... Hope you enjoy your 562 as much as I enjoy mine! Joe
Thought I'd ask on the off-chance somebody has a noise blanker board available for the 544... Love the old 544 but drowning in summertime electrical noise here...much of it blankable on many radios.
Reading comments on eham and elsewhere, the Triton noise blanker is made out to be fantastic! For an example of a useless NB, try my Omni V. Does almost nothing. I used Corsairs for years and have t
Mike: Found a pic on Ten Tec Wiki http://www.tentecwiki.org/doku.php?id=249 Click on pic for bigger version There are three small toroids but nothing exotic (to the eye). Joe N5KAT On 7/25/2010 7:03
Anybody have a schematic for the old G4PKT Omni V/VI product detector mod using the Plessey SL6440 chip? Found one chip last year and a source for a more online, so I am tempted to give it a try. I d
Audio is a actor of phones. Quite poetic as-is, but I interpreted that as "audio is a factor of phones" which can be very true. "All the world's a stage... and audio is an actor of phones" hihi Joe
I second this...clean the power supply connectors with DeOxit. This is a classic Ten-Tec maintenance procedure that solves all sorts of faults that don't seem to have anything to do with dirty power
Dan: This might sound disconnected, but have you tried cleaning the power supply connectors on the back of the rig and from the supply? All manner of flaky symptoms can be cleared up by doing this, i
My sense is that it is best to identify the caps one by one. There aren't really that many different values and some are more involved with digital noise bypass then others, so there are application
Steve: If you want a sure bet, pick up some Sanyo Oscon caps. These are superior quality organic polymer electrolytics: High temp, very low ESR, very long life...tantalum replacement grade and come i
There is WAY WAY too much AF gain in the Omni V. A factory recommended fix was posted on this board recently by Don K6RV on 16 Feb 08. There is also some overdrive of the product detector going on. W
Replacing the stock 1st IF sideband filter with the 2.7 INRAD is also a fabulous improvement which goes beyond mere bandwidth considerations. I have never seem this adequately explained, but the ears
Sadly, bad audio is "normal' with the V. Painful is more like it. Yes, there is too much gain in the audio circuit, so you blow your head off by even breathing on the AF gain knob. Taper of the AF p
Look for 105 deg C, Low ESR, High Frequency caps. Find caps designed for bypass and decoupling in digital circuits--switching power supplies,logic boards, and the like. Check the Mouser catalog--I th
First order of business with any flaky Omni V behavior is to clean the DC power connectors on and to the rig. Gunk or oxidation on this connector will do things you never would attribute to a dirty p
For display irregularities, first order of business is to clean the power connections on the back of the rig and the contacts from the plug from the power supply with some Deoxit and pipe cleaners. M
