Astron rs 35 m manual

You can login to do that! I have seen this happen with a substation where we have this gigantic buried ground mesh. I found that site and referenced it above also. On further searching, I found a wealth of info here: When you get a transient lightning, fault, normal device switching it can behave in difficult to predict ways. This file is downloadable free of charge: Please, do not make a copy of the downloaded manual and do not offer to sell it, just use personally to repair defective appliance!

While the Astron Linear PS designs have changed through the years — largely due to changes in electronic components RoHS, obsolescence, etc. Two white LEDs with a single dropping resistor is all that is needed.

The Astron website appears to only have a catalog and no support information. Trying to balance out our three phase loads we noticed that there was an unaccounted for power loss. How to contact Icom America Technical Support: As for illuminating the meter, that is a piece of cake. Picked up a used RSM. Not too much in there but you can never have too much info. If you are not familiar with electronics, do not attempt to repair!

Most other manufacturer sites I have visited have PDF download files for their equipment. For some new radio amateurs Satron is a second language, and can better understand some electronics concepts and repairs via video YouTube instruction or pictorial diagrams. April 26, The only other related thread I found so far is: Maybe I need to try someone else there.

I have seen this happen with a substation where we have this gigantic buried ground mesh. Checked earth safety ground to chassis resistance: Two white LEDs with a single dropping resistor is all that is needed.

Anyone have a copy or know where I could obtain it? How to contact Icom America Technical Support: These free programs can be found on this page: The problem had been there for years but it was due to a fault in the way the substation was designed.

Usually this would be much more pronounced on instrumentation loops industrial control with pressure transmitters operating off of a mA current loop for example. New to Ham Radio? The problem I see with the drawing above is that a source of AC current is shown in the safety ground lead running to the power supply case. There normally should NOT be any current flowing in the safety ground lead. If there is then you have a defective, leaking power supply or other device connected to that branch circuit.

If you remove the -DC to case connection in the power supply and there is leakage in the safety grounding conductors then you now have a voltage difference between the radio case and the power supply case and that's not good either.

I submit that if you have currents flowing in your safety grounding conductors then you should locate and correct the leaking device rather than cutting the jumper inside the power supply.

That grounding bolt on the radio is intended to provide a permanent bonded connection to your station ground rather than relying on the coax shield for the ground connection.

AA4PB , Mar 6, Seems to me that if there is no antenna connected, then the radio has no more lightning risk than any other electrical device in the house. N0TZU , Mar 6,
