I would still highly advise against using that cheapo antenna adaptor on a whip right next to your new power supply. You seem to be throwing money at the wrong part of this temporary problem. The part that you say "you want to do it correct" is highly suspect if you're not doing "proper" antenna installations and setups.

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

I am looking into doing both the power supply AND antenna installation correctly. Are you saying that antenna solution that I am referring to in post 17 is not a good solution?

A 15A power supply is more than enough for a 50w radio to transmit on high power.
Likely the issue is him transmitting with the antenna directly connected to the radio, causing RF to get into it.

the way your post-train-of-thought has been proceeding made it seem like you wanted to throw money at a fancier power supply , without getting the RF out of the unit in a way that will not affect everything near it. Get a remote-able antenna up, with proper feedline (you can get RG-8x, an NMO mount that you can put in an old sheet pan, and a whip for a pittance these days - much cheaper than a bigger power supply) . Get the friggin' RF away from that power supply.
All the standby power in the world won't help if you can't get the RF out of the radio.
And away from the operator and the radio. Bad practice, RF Exposure, and that was on the test.
I'm not sure what a remote-able antenna up is but I am going to order the stuff listed in post 17 and get that antenna outside the house.
I understand this is a 50 watt radio, but as I've mentioned earlier, I have it turned down to low power. I was under the impression it was only 5 watts, which is no more than my portable, but I will check and see for sure when the swr/watt meter comes in.
It's a sort of a portmanteau for "remote capable" antenna. Rather than be absolutely literal with what I meant, I took some liberties with the words used. Apologies, won't happen again.
I see your followup post also says "but i turned it down to 5watts..." as we mentioned earlier which you are still shooting directly into the power supply. Put a length of coax between the antenna and the radio, MOVE THE EMITTED RF from the immediate proximity of the power supply, and try again.
you also said in post #17 you want to do things correct.

I'm pretty familiar with the English language, so I understand you were combining words there. At any rate, I still don't know what a"remote capable" antenna is. I've never head the term before. I completely understand the RF Issue now. It's been made very clear. as mentioned before (again, in post 17) I do want to do things correctly. I plan on putting a mobile to base conversion kit with mobile antenna outside as to MOVE THE EMITTED RF. I am simply trying to figure out if this solution is correct or NOT.How many people need to tell you that moving the RF away from the back of the radio is most likely the solution before you believe it, and stop pointing fingers at the power supply?
You're obviously frustrated with this, I understand that. But you're arguing semantics when the issue here is practical application. You first thought it was the power supply as the root of the problem, which it is ...and it isn't. That model might not tolerate even the 5 watts ERP you are putting out in close proximity, and may cut out when used at particular frequencies. I see you've had your license for almost 5 years now, there are hundreds or maybe even THOUSANDS of licensees here with DOZENS of years of experience that are all going to tell you the same thing. Your antenna setup AS YOU HAVE NOW is the weakest link in your system. Buying a new power supply, as you alluded to very early on in this arduous thread, might solve that transient problem as you have...but the poor practice of having a whip on the back of a transciever unit isn't helping you. Sure a newer biggier more-better fancier power supply (RM-35 linear type) might prevent the shutdown under certain frequencies issue you're having now, but the bigger fact remains...you are exposing that current power supply and yourself to unacceptably high local RF conditions, even at 5 watts.
you can literally get a $10 dollar mag mount antenna, a length of coax and appropriate connector for that set up, stick it on a ground plane and see if the issues persist.
I'm not going to argue with you over this any more. Your current set up is not in the best practices of the hobby, that is why you are having issues. All that stuff you keep referring back to in "post #17" means nothing if you don't do it.
Get a remote antenna, some coax, some connectors...hook the radio up correctly, get some distance between your transciever and the power supply and try it again.
Good luck.

I'm not sure what your hang up is, when I have made it perfectly clear that I have realized the problem, but its getting no where. The power supply NEEDS to be replaced PERIOD! due to the RECALL alone! I'm well past the power supply, Its a done deal, new one is ordered and on its way, there is nothing else to say about it! As I said before, I COMPLETLY UNDERSTAND the RF issue. I COMPLETELY UNDERSTAND that the current antenna setup as is, is an issue! No one is arguing that! I have comprehended what others have said and no one needs to keep telling me to move the RF away! It wasn't mentioned until post 10 about the antenna issue. and if you will notice, my next reply after that was about trying to figure out if conversion kit setup would be correct. I have mentioned several times about a very specific antenna solution since I have realized that the current antenna setup is not working! I have even asked you specifically if you though is was a good solution! I understood what you were saying about the mag mount antenna but I rather have a more permeant solution which is why I asked about the mobile to base conversion kit. Your absolutely correct about this thread becoming arduous!
Thank you to everyone that helped point out what I need to fix in this setup, I appreciate all the help. At this point, everything has been ordered and is on it's way.

Good lord. A 50w radio with a properly tuned load should draw less than 12A. How many radios do you think he will be talking on at once?

As I said above, I prefer my power supply to loaf at a ~50% load. That's me... and my usual reccomendation. Further, the larger power supply should easily run additional radios, e.g. an HF transceiver, and receivers KG5HHS may buy in the future. Over to you.
