Yes I understand but the tires are in two pieces, the gray-black outer and the white insert that gives the knob the look of having a white ring feature for cosmetic purposes. I have more tires than i
If an Orion is voltage sensitive in any way, change the electrolytic capacitors on the A9 Power Distribution Board, ALL OF THEM. 90% of the time, tis will resolve the issues. Gary W0DVN PS: This is t
OK. There are other things that can go wrong with the A9 board so I am still focused on it. Can you put a voltmeter on the 5 volt line as you vary the 13.8 volt input? It should not change very much.
I have a late Eagle. It has a coax going from the RX-TX board to an RCA jack on the back. The cable plugs into TMP jack 15. This is not shown on the Eagle schematic I have. Is this an IF output? If s
I answered my own question. This is indeed an IF output and, with the analyzer gain cranked way up, I get a spectrum of the Eagle. However, I get a constant peak 25 KHz above the 9.000 MHz centerline
Its not QUITE useless because one can indeed get a band spectrum using it. However, the strong peak at 9.025 MHz is stronger than the band spectrum. It is fixed in position so that frequency would be
Can you locate what smells burned inside the radio? You can try using a straw inserted into your nose to directionally sniff around to see if you can pinpoint the burned part. Plug your other nostril
When I replace the encoders, I disassemble them and remove the spring that makes the detent operate in stepwise fashion. If you do not do that, some adjustments will double step. It takes about 5 min
There is a lubricant in the encoders, a silicone based material whose intent is to both lubricate the contacting surfaces to prevent wear and to coat the parts with a movable material to prevent oxid
Change all of the electrolytic capacitors on the A9 board with low ESR 105C rated capacitors. Most Orion problems like this are caused by A9 board problems. Gary W0DVN
You are not going to damage the radio by using a long cable. I would not be worried using 25 feet length. If you have ay RFI problems, just pass the cable through a ferrite core for a few turns, with
Greetings: I am working on an Argonaut 505. The 9 MHz BFO is low in frequency, cannot be pulled in. This resulted in severely reduced output power in CW or Tune since the carrier is now out of the fi
Actually I have had good success in getting email response from Ten Tec. Gary W0DVN Also, I have two of the late Orion II VFO knob tires in excellent condition. $20 for the pair shipped in CONUSA.
