[Flexradio] duty cycle heat
I read with interest the emails about the duty cycle and heat test. As a digital contester, my question is...

Re: [Flexradio] The QST Review
Hello Flexers, Overall, we at FlexRadio felt it was a fair and balanced review. Note that most of the software feature wishes in the article were already available to SVN users at the time the article was written. These will be in the new official release as soon as RX2 changes are frozen. Let me give a great example of how a true Software Defined Radio is different from legacy radios. The QST article commented on how it would be helpful to have buffer settings by mode. Guess what? In the RX2 SVN branch, we have already implemented RX/TX buffer settings by mode for Phone, CW, and Digital. This will merge with the main branch too. Yes, you can use the FLEX-5000 at 100W for RTTY contests. We did aditional thermal testing after the manual was published that allows for full duty cycle operation at 100W. Our testing was done with 100W key down for one hour with thermisters attached to the final transistors. The temperature stabalized after about 20 minutes within a hot but safe range on the finals. The QST article is in error about the fan. It always runs and is virtually silent. The FLEX-5000 and the SDR-1000 will continue to "just keep getting better." 73, Gerald Gerald Youngblood, K5SDR President FlexRadio Systems 13091 Pond Springs Rd. #250 Austin, TX 78729 Phone: 512-535-4713 -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Sweeney Sent: Friday, May 30, 2008 3:24 PM To: flexradio@flex-radio.biz Subject: Re: [Flexradio] The QST Review Flex Gurus, The review, among many other things, states " the Flex-5000A is rated at 100W continuous duty on all modes.

Also, the review sounded as if the fan does not run continuously, only as needed. My fan runs at one speed continuously, even on receive only. Was this changed in later units? What is the highest PA temperature we should allow? I thought 50c was the maximum we should allow the PA to rise to. AFSK ops , and even PSKers , would like to know. I also do 1 watt WSPR mode (K1JT) with amazing results, so temp not an issue there. Overall, I thought the review was fair and balanced.

Re: [Flexradio] The QST Review
Hi Lee, Well, I tend to agree with you. ARRL doesn't dare offend it's current advertising base. Look what happened when they took on the antenna advertisers. That said, I thought they were pretty generous in some areas: mainly CW and AGC and NR. IMO, Flex has a long ways to go in these areas and the League could have been much harsher! On the other hand, they certainly could have mentioned how much easier the Panadapter makes it to use a whole band segment or what a pleasure it is to use Flex with the digital modes. very best regards Rob AB7CF On Fri, 30 May 2008 12:44:00 -0500 "Lee Mushel" <[EMAIL PROTECTED]> writes: > John B. > > I felt the review gave a more favorable picture of the Flex5000A > than I would have expected.

here it is
First change the case statements in SetState to the following;
case "console_top":
this.Top = Int32.Parse(val);
FormOnScreen(this);
break;
case "console_left":
this.Left = Int32.Parse(val);
FormOnScreen(this);
break;
case "setup_top":
SetupForm.Top = Int32.Parse(val);
FormOnScreen(SetupForm);
break;
case "setup_left":
SetupForm.Left = Int32.Parse(val);
FormOnScreen(SetupForm);
break;
case "mem_top":
MemForm.Top = Int32.Parse(val);
FormOnScreen(MemForm);
break;
case "mem_left":
MemForm.Left = Int32.Parse(val);
FormOnScreen(MemForm);
break;
then add the following new Method to the Console class;
void FormOnScreen(Form f)
{
// Get the bounding rectangle of the windows logical desktop
// the one problem with this routine is if one screen is much larger
// than another but how many people place there forms across screens!
Screen[] screens = Screen.AllScreens;
int Left, Top, Right, Bottom;
Left = Top = Right = Bottom = 0;
for (int i = 0; i <= screens.GetUpperBound(0); i++)
{
if (screens[i].Bounds.Left < Left)
Left = screens[i].Bounds.Left;
if (screens[i].Bounds.Right > Right)
Right = screens[i].Bounds.Right;
if (screens[i].Bounds.Top < Top)
Top = screens[i].Bounds.Top;
if (screens[i].Bounds.Bottom > Bottom)
Bottom = screens[i].Bounds.Bottom;
}
// if the forms left side is left of the logical desktops left then
// set it to the left side of the logical desktop
if (f.Left < Left)
f.Left = Left;
// if the forms right side goes beyond the right side of the logical
// desktop then position the form so the right side of the form
// coincides with the right side of the logical desktop.
else if ((f.Left + f.Width) > Right)
f.Left = Right - (f.Width);
// if the forms top is above the logical desktops top then
// set it to the top of the logical desktop
if (f.Top < Top)
f.Top = Top;
// if the forms bottom goes beyond the bottom of the logical
// desktop then position the form so the bottom of the form
// coincides with the bottom of the logical desktop.
else if ((f.Top + f.Height) > Bottom)
f.Top = Bottom - (f.Height);
// On initial startup it is the Location property that sets
// the position of the form
f.StartPosition = FormStartPosition.Manual;
Point pt = new Point(f.Left, f.Top);
f.Location = pt;
}
