Re: [Flexradio] Help!
If you're using the parallel cable, be sure nothing is in the printer queue assigned to the port you are using for the SDR. I used to have a printer hooked to the same parallel port I now use for the SDR, and accidentally sent a print job to that old printer that is not in use now, and it freaked out the SDR. 73 Brian On 3/24/07, Tom Thompson <[EMAIL PROTECTED]> wrote: > Hi RJ > > I have had things like that happen when the data base gets corrupted. > Load in your backup data base.

Larry, you might want to try Line Isolators. They break any ground loops and also eliminate any hum.

Use the NT1A for recording where it will shine. The SDR needs only a reasonable mic. SDR's built-in EQ can adjust for most short comings.

When finished the Memory Frequencies were copied for a previous Database. While admittedly highly extreme, these settings provide some interesting transmission characteristics: 1. They provide maximum voice to room noise ratio. While talking, the room noise is suppressed by 15 db. 2. They provide about 2 seconds of suppressed room noise to allow taking a breath before the Leveler starts to increase the mic gain. Locals report a natural good audio with no objectionable room noise even though I have the SDR fan, computer fan and the AL-82 blower all running within 3 feet of the microphone.

When I use the scroll wheel in MixW (click over the waterfall and turn the wheel on my mouse), unless I turn the wheel very, very, very slowly (that is, much slower than one wheel click per second) after just a few wheel clicks (seven seems to be the magic number), MixW loses its mind and displays a frequency such as 732.344.939.

Re: [Flexradio] external OCXO, silly question
The 50 ohm termination does two things: 1. It terminates the coax from the oscillator so you reduce ringing and the possibility of increased jitter that results, and 2. The maximum input voltage that the DDS can accept is fairly low, and an unloaded clock signal can fairly easily exceed that level. The load helps ensure the voltage will be under that limit.

I am in the process to connect an external OCXO to the DDS board and saw that the external XO connection kit handle a 50ohm resistor to 'load' the input of the DDS clock. Is it mandatory ? related to the fact that the DDS clock input Z is >> 50ohm ?.
