Re: [Flexradio] Power Supply Advice
For guys who live in the Cleveland/Euclid, OH area: HGR Industrial Surplus, 20001 Euclid Ave, Euclid OH 44117-1480 Phone, 216-339-2799, ask for David Cehlar They have about six or seven clean commercial Tenma 30 Amp Max (Analog) DC Power Supplys, Model 72-630 available for $49.99 each. The one I bought on Wednesday has a calibration sticker of 3-31-11 on it. I don't have any interest in this company and just noticed these supplies when I visited the warehouse with my son-in-law.

Re: [Flexradio] Power Supply Advice
Dudley, I agree. Our club had an Astron RM-35 that had the series pass transistor fail (short). The output voltage went to the maximum provided by the transformer the 2 rigs connected to it were damaged. The Yaesu FT-950 was repairable, but a Yaesu FM rig was not economical to repair.

Re: [Flexradio] Power Supply Advice
Same here, I have lost a BUNCH of 2N3055 pass transistors over the last 30 years and equipment that was attached to the Power supply, Also the big Electrolytic goes bad and you have a lot of AC ripple after about 5 years of operation. If your equipment is important to you rebuild the Astron P.S. every 5 years or so of continuous operation, you may be lucky enough to get 10 years out of it but your asking for trouble, this is why around here you never see Astron Power supplies at a commercial Mountain top site on commercial radio equipment. Most Commercial installation these days use there own design, I do know Kenwood systems use Duracom switcher Pwr. Supplies but these are a bit noisy on HF so don't play well in Amateur use. 73's Bret WX7Y -Original Message- From: FlexRadio [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Ray, K9DUR Sent: Thursday, June 12, 2014 5:26 AM To: 'Dudley Hurry'; 'Dave Movius' Cc: flexradio@flex-radio.biz Subject: Re: [Flexradio] Power Supply Advice Dudley, I agree.

Re: [Flexradio] Power Supply Advice
The moral of the story is that every time you chop some something (like a switching supply), you create noise. It is in the math. This is why the Alinco has a adjustable frequency option to move the birdies. The old IRON Astrons are much quieter by design. You aren't chopping anything. :) Mike va3mw On Thu, Jun 12, 2014 at 2:15 PM, Paul w8...@q.com wrote: I use an Astron SS-25. I think it is a 25 anyway.

Hi All! This over protection module is something that you can buy in stores or must be built ? I am using with my 6700 a Astron RS 70 - M ( 70 amper). I have it since many years.

Re: [Flexradio] Power Supply Advice
I have three of these, bought at separate times. The oldest is 20+ years to the most recent one at 10 years. Had one failure where the PC board that bolts to the terminals of the filter cap came loose, heated up and let out the smoke. Fixed that, checked the others, found one loose, fixed it and no failures since. Using screw terminals through a plated through hole in a PC board and relying on the clamping force to make a good connection is a bad idea. Even glass epoxy boards will give a little under pressure and the connection will become loose over time. Probably a good idea to check these caps. These are on the analog supplies. Not sure if this lousy practice was followed on other Astron supplies.

Some have never been turned off. Sure there are some failures but it does not appear to be a prevalent occurrence. For what it’s worth I have one but use the Icom PS-125 switcher instead to power my Flex. Several years ago they were plentiful since they gave them away with the 756 PRO series radio and I prefer its size. 73 Ross K9COX Sent from Windows Mail ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz

Keep am eye on the analog power supplies , over time they will begin to lose voltage regulation and will need to be repaired or replaced. 73, Dudley WA5QPZ Sent from my iPhone On Jun 9, 2014, at 9:28 PM, Dave Movius dave.mov...@gmail.com wrote: TOM, I use Astron 35 amp linear power supply with heat sink for Flex 6700.

Re: [Flexradio] Power Supply Advice
Many thanks for all the helpful inputs - both on and off list. Think for now I will just be content with my old, trusty Astron. I probably will operate the new rig as I have the 3000, at lower powers. Also, checking the Astron site I found even the old Astrons have good over current and voltage protection. To answer one of the questions - I did not see a recommended supply in the Flex documentation for the 6700. The specs are for max currents of 3A RX and 23A TX. The Astron 20A specs are 16A continuous and 20A at a 50% duty cycle. So, it is not off by too far. Thanks again. This list is really a great resource. Hope to see you on the bands. 73, Tom K1FR -Original Message- From: FlexRadio [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of TM Sent: Monday, June 09, 2014 5:45 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Power Supply Advice I have been using a pretty old Astron 20A supply for my Flex 3000.
