[Flexradio] You have asked another good question
Hello Mike, You have asked another good question (below) The thing to remember is that the bias setting is typical of most ham radios, this is because it is needed to operate class AB1 or AB2 for SSB. WHILE IT WOULD BE NICE to be able to change the bias (lower or shut of resting current) for CW contest, Flex does not give us the control to change class of the finals to B or C. The good news is that Flex has a very strong and well built set of finals and will last many years. Much better than just about all radios on the market today. If you wish to increase the air movement for contest or other long transmissions, click on setup, then under tab general, the tab Hardware Config you will see Fan Temp threshold. From the factory it is set at 40c to start fans (slow speed). For Contest or other high use time, you can consider setting it at 30c. This almost runs the fans (slow speed) all of the time. It is great for operating CW or RTTY contest. I recommend setting it back to 40c for normal use. Again, the Flex has one of the best set of finals you will find. It is tough. Flex makes a great radio. I know of none better. 73, Bruce, W8HW, w...@att.net I operate Flex and fix the rest I repair two way radios including ham radios - Original Message - From: Mike mi...@m0aws.co.uk To: W8HW w...@att.net Sent: Monday, September 05, 2011 10:47 AM Subject: Re: [Flexradio] 58 Degrees and rising Hi Bruce, Perhaps I would be better off running my F3K at very low power and then using my amp to give me the full 100w output, currently I've just been using the F3K barefoot, can't remember the last time I switched the amp on actually!!

The bias of the finals (and drivers) are such that even if you were to MUTE all audio and key the transmitter lots of heat is generated. This happens even if you see no power out, Try this some time, turn your audio all the way down and key your transmitter. Note that the current from your 12v power supply jumps up. If you were to leave the transmitter keyed, the temp of the final rises and your fans will start to run. Because bias (causing resting final current) results in no power out thus it is ALL heat. 73, Bruce, W8HW I repair two way radios including ham radios - Original Message - From: Mike mi...@m0aws.co.uk To: flexradio@flex-radio.biz Sent: Monday,

Re: [Flexradio] You have asked another good question
Dan, What version of PSDR are you running? In PSDR v2.2.2 under setup/general/hardware config in the lower center of the screen there is only a check box for Use Ext Ref Input Receive Only. Across the bottom are boxes for Factory Defaults; Import Database; Export Database; OK; Cancel Apply. In the right center of the screen under DDS is a check box labeled Expert. When I check that box 2 controls appear labeled Clock Offset IF(Hz). It looks like access to the fan control has been removed in v2.2.2. 73, John, N8WNA -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of dan edwards Sent: Monday, September 05, 2011 12:30 PM To: FlexRadio@flex-radio.biz; Burt Subject: Re: [Flexradio] You have asked another good question setup / general / hardware config..low center of screen.. 73, w5xz, dan --- On Mon, 9/5/11, Burt k1...@yahoo.com wrote: From: Burt k1...@yahoo.com Subject: Re: [Flexradio] You have asked another good question To: FlexRadio@flex-radio.biz Date: Monday, September 5, 2011, 4:27 PM I do not see the fan adjustment How do you see it?

Re: [Flexradio] You have asked another good question
It is only applicable for the FLEX-3000. The FLEX-5000 has a single constant velocity, high volume fan for cooling (assuming you do not have the V/U installed). The 1500 has no fan. -Tim --- Tim Ellison, W4TME Product Management, Sales Support FlexRadio Systems^(TM) 4616 W Howard Ln Ste 1-150 Austin, TX 78728 Phone: 512-535-4713 Ext. 223 Email: t...@flexradio.com mailto:t...@flexradio.com Web: www.flexradio.com http://www.flexradio.com logo /Tune In Excitement^(TM) PowerSDR^(TM) is a trademark of FlexRadio Systems/ On 9/5/2011 1:57 PM, John Swink wrote: Dan, What version of PSDR are you running?

WHILE IT WOULD BE NICE to be able to change the bias (lower or shut of resting current) for CW contest, Flex does not give us the control to change class of the finals to B or C. The good news is that Flex has a very strong and well built set of finals and will last many years. Much better than just about all radios on the market today. If you wish to increase the air movement for contest or other long transmissions, click on setup, then under tab general, the tab Hardware Config you will see Fan Temp threshold. From the factory it is set at 40c to start fans (slow speed). For Contest or other high use time, you can consider setting it at 30c. This almost runs the fans (slow speed) all of the time. It is great for operating CW or RTTY contest. I recommend setting it back to 40c for normal use. Again, the Flex has one of the best set of finals you will find. It is tough.

I'm normally operate CW so the unit doesn't get as hot as when I am running WSPR. How would you suggest I add some extra cooling to the F3K?

I've used Peltier Heat Pumps in professional environments in the past to control device temperature, perhaps this would be a good option for the F3K, although they do require a fair current to make them operate well.

You can set the temp at which the fans go to high, Adding some extra cooling will help also, as the fan slow down when not transmitting, normally we listen more than we transmit. I did a test. I turned off both mic gain (to zero) and power out to zero as well. Then I keyed the MOX and watched the temp rise. With fan running, the temp went up to 49.1c (120.38f). That is when I shut the TX down. Remember that is with FAN RUNNING and only resting current (no power out). That means that during times of CW, I am not only generating heat during the dits
Re: [Flexradio] You have asked another good question
The original thread started with a person that had a Flex3000 and lot of people started asking question on top of that. 73, Bruce, W8HW - Original Message - From: Tim Ellison, W4TME t...@flex-radio.com To: flexradio@flex-radio.biz Sent: Monday, September 05, 2011 2:30 PM Subject: Re: [Flexradio] You have asked another good question It is only applicable for the FLEX-3000.
