July 28, The LEDs can be attached many ways, including a hot glue gun. If you can’t find the schematic of the RSM, let me know. If you want to join us and get repairing help please sign in or sign up by completing a simple electrical test or write your question to the Message board without registration. Astron sent me a manual in e-mail.

I have seen this happen with a substation where we have this gigantic buried ground mesh. The only other related thread I found so far is: How to contact Icom America Technical Support: As for illuminating the meter, that is a piece of cake.

I cannot find anyhting on Astron’s website, except their catalog. Good luck to the repair! Checked earth safety ground to re-35m resistance: There is no preview for this item!

As for manuals, I wasn’t aware they had one or why a person would need one. Repairing the Astron RSA http: These free programs can be found on this page: Usually this would be much more pronounced on instrumentation loops industrial control with pressure transmitters operating off of a mA current loop for example. Trying to balance out our three phase loads we noticed that there was an unaccounted for power loss. There are also Battery “BB” versions of the power supply.

We’ll see you in a couple of weeks it’s that deep of a bench. May 18, April 26, If you have grounds on your radio equipment at other places like the antenna, tower, coax you are creating two earthing ground return paths of different capacity and with ever so slight differences in potential.

Not too much in there but you can never have too much info. When you get a transient lightning, fault, normal device switching it can behave in difficult to predict ways.

You can login to do that! Because the ground conductors are also of different gauges wire size the DC return current from the radio is now also going to be trying to share the connection through the earth ground mnaual. Also checked negative side of DC output: Maybe I need to try someone else there. It appears you have a handle on operating the unit, even to the point of correcting meter errors. Searched all over for copy of whatever manuals might have been available but cannot find anything.

Please, do not make a copy of the downloaded manual and do not offer to sell it, rs-335m use personally to repair defective appliance!

However, I suggest you Google this for a more detailed and no doubt better manyal of doing this. The Astron website appears to only have a catalog and no support information. The last I checked Astron website had schematics of all their linear power supplies. This creates what is known as a “ground loop” that can introduce AC hum in to the DC supply ground return leg. For some new radio amateurs English is a second language, and can better understand some electronics concepts and repairs via video YouTube instruction or pictorial diagrams.

Instead, contact your nearest service center!

Looking for other manual? I also thought maybe my meter lights were burned out, as some have noted, but on mahual searching found that since my unit has a fixed power cord, it’s likely older and never had meter illumination. Sorry I just had to.

On further searching, I found a wealth of info here: August 14, July 31, I had called Astron but they were not very helpful, only saying “it depends” and manal offering any rationale.

The schematic is really all you need. If this is the reason, announce it with the blue man icon on the top and I remove it. You could suffer a fatal electrical shock!

But this means that the line-cord on the power supply is also acting as the safety bond for the xstron I will say computer, instead of radio. The only way to find out is to try it I guess. Contact the site with comments or questions.

Is this the correct site? New to Ham Radio? While the Astron Linear PS designs have changed through the years — largely due to changes in electronic components RoHS, obsolescence, etc. April 27, So, if you do not have any other sort of ground connection on the device you can safety bond the negative return to the earth ground. It ended up being in one ground conductor that was not bonded correctly,it was a MCM cable that had 6 volts at amps running through it.
