Elastic cord found in a fabric shop. And when you finish the operating session, scroll it to the left end to reduce the continued strain on the cord. 73 Bob, K4TAX Sent from my iPhone
I thought it was left for parking, but it could be right. They typically last 10 to 15 years. Perhaps that explains why I dont recall the preferred position. Bob, K4TAX Sent from my iPhone
Although an excellent wide marching range tuner it will handle the power as well. If one is experiencing SWR drift, that indicates the disc ceramic caps are getting hot and changing value. They are a
Most likely the cap on the CPU reset line has decreased in value due to age. Replace it with one of equal value. The backup battery requires power to be applied frequently to maintain charge and memo
Jim: How long has it been since the connectors internally were cleaned? Likely never. So it is time to unplug each one, scrub the male pins with a Q-Tip with contact cleaner applied and plug it
When I stated clean connectors I didnt say just a select few or ones. They ALL should be cleaned. The Q-Tip provides additional scrubbing action where as just applying any cleaner does not provide sc
As one that has repaired many radios for others over the years , I find that radios which sit on the shelf on in a box "being saved" are simply deteriorating in the box or on the shelf. Make it a poi
I suggest a slightly different approach regarding braided material. I choose to use #10 AWG Auto Primary wire, green in color. That is insulated wire where as braid is not insulated. It is al
You should not consider any internal grounding method for lightning protection. That MUST be done on each feed-line and rotor cable outside of the structure. The purpose of connecting each piece o
I sell on E-Bay when I want top dollar for my items. I buy elsewhere for generally a lower price. At the same time, I've stopped selling on E-Bay because of the fees and cost to list and sell. T
The only one I'm aware of is the Tentec Argonaut VI on Groups.IO. It has about 250 members. 73 Bob, K4TAX Over the years, participation dwindled, and I haven't had an email from the group for a cou

There is a RC timing circuit on the microprocessor RESET line. It is common for the value of the C electrolytic to decrease with age. Thus the original RC time constant value has changed. That can
In reference to my earlier post......the RESET function on the microprocessor is a combination of R16 {100K} and C58 {1.0uF} on pin #1 to ground of U7. I suggest replacing C58 with a new one and in
Relays on the Low Pass Filter board may have an open coil. 10 & 12 share the same filter section. Two relays per filter section, coils in parallel. Also I recall a small RFC in series with the coil.
Just connect the SDR receiver Ant to the 9 MHz IF output. The ACC1 is not used. The USB connector goes to the computer. I use HDSDR software which handles the SDR and the Argonaut from your computer.
Bob; My concern is that the supply may be noisy in as much the original application was not an RF environment. You may need to add CORCOM line filtering and add large torroids on the DC output. In ma
To answer the question; Can somebody explain me the differences in between Omni VI Plus or VI Opt. 3 please? Evolutionary changes in no particular order: * The 564 has a different font silk-screened
