[Flexradio] 1 Watt Flexradio to be for sale

Hi, In a couple of days, I'll have my new 100 watt Flex here and after it's set up and everything is fine, my 1 watt unit I purchased new October 2006 will be for sale. Sale to be CONUS only. Email me off list if you need one (especially for the microwavers). Thanks, and 73,

Re: [Flexradio] Residual carrier was SB question

Hello Flex guys I did some more research into my suppressed carrier on SSB and key up levels on cw. I am a little surprised that someone "in the know" did not mention this. But as it turns out, the LO on transmit must be shifted to be the carrier frequency on SSB. I verified this by disconnecting

Hi and Help Please I downloaded the VS C# 2005 EE stuff and the SVN Stuff from: svn://206.216.146.154/svn/repos_sdr_linux/trunk It seems that I need a bit more than what I got, I get an 'not installed' error on Hardware Test vcproj Could someone lead me in the right direction? Thanks Much Bru

Re: [Flexradio] PA calibration routine

There are some compensations built into the power reading mechanisms that take the various ADC values @ 100W for the different bands into account. However, this is one of the non-linear contributions to the error in both the calibration and the power reading. Eric Wachsmann FlexRadio Systems > -

I know that my LP-100 Power Meter is calibrated band by band, and so I'm wondering...how flat across the spectrum (from 2 to 30 MHz) is response of the directional coupler within the SDR's PA? Per the algorithm listed in Eric's email, any changes in frequency response of the directional coupler co

So its a Big Horse Small Horse problem. If you want the same amount of poop out of the small horse as the big horse then you gotta feed it more hay. The gain number is the size of the horse. I wonder how Terman would state the problem. 73, Larry K2LT Eric Wachsmann wrote: > A full explan

Re: [Flexradio] PA calibration routine

A full explanation will involve delving into the source code. The output voltage is set by a series of formulas starting with the Drive setting. In console.cs you can see the event handler for udPWR_ValueChanged uses the following formula for 100W setups:

Re: [Flexradio] PA calibration routine

I have done similar "boosts" to Drake TR-7 solid state amps where the 160 and 10 meter bands have lower output. What I discovered is for the most part the carrier does not increase that much. Most of the increase in apparent power output was due to harmonics and garbage increasing faster than

Re: [Flexradio] CPU Percentage question

Jeff, 512 MB RAM is not enough to keep from paging memory to the HD. If you bring up the windows task manager and watch the memory parameters under Performance and try to correlate them with CPU %, it might give you a clue. As to why other systems operate with 512 MB RAM, I don't have any id

Re: [Flexradio] CPU Percentage question

Jeff; I might have missed seeing someone suggest this, but I had a similar problem that turned out to be an overactive virus detection program. I uninstalled Symantec and installed the free Avast!. Voila, vastly reduced "periodic" high cpu rates. Besides being free, it's a very good program. K
