Smart SDR Shuts down.

KG5PTE

Hello sometimes when I key up on my radio my SMART SDR quits for no apparent reason. My SWR are 2.1 and bellow.

Thank you.

It is a freeware program developed by a Flex user. It does many things well. And provides features missing in SmartSDR.

This often happens when the radio voltage dips to a too low level or RF getting into the power supply.

The simple test is to try it at 1 watt RF out and if it works, increase it until it fails.

Monitor supply voltage using either. FRStack or K9DUR monitor.

I have the same problem and I never experienced it before. Voltage is good a HF is well blocked.

Mike & John...

If SmartSDR quits (on the PC I assume) how can the voltage to the radio be revelant?

John KB4DU

If SmartSDR loses connection with the radio, for example the transmit power required drops the voltage bellow below the minimum SmartSDR will quit. I’m not telling how I know.

Well I sure hope the the Powerwerx SS-30DV , 30 amp , 25 amp continuous that was given to me when I bought my Flex 6400 is enough power (amps) to run this radio. Because that is what I am using. And my Antenna (An Alpha Delta DX LB Plus antenna) is on the other side of the house with 95 feet of RG-8X coax with a 1 to 1 bauln. (RF Choke) at the antenna feed point. So I hope it is not underpowered or RFI.

Sometimes a low voltage to the radio can occur because of a poor connection that introduces resistance that can cause low enough voltage on transmit to cause the radio to shutdown. The easiest way to check it is with FRStack. It can monitor the voltage at the Powerpole connection on the rear of the radio. Or you can use a VOM if you have one.

Tell me more about FRStack I never heard of this. Is this hardware or software ?

John KB4DU

FRStack is a free download. In Addition to allowing acces to voltage levels inside the radio, it has a very versatile, sophisticated memory system, storing many more items than the flex does. It also serves as a spots collector, and several other features. I don’t operate without it.

Where do I monitor power levels with FRStack ? Another app I was told to get is Slicemaster.

Thank you.
