Hi Dale! Disable all power saving options. Look for check boxes saying something like turn off this device when not in use to save energy.

Re: [Flexradio] freeze up with a 1500
Hi Dale! Some PC's share the USB buss between multiple ports, or the USB may share a IRQ with other devices. Try a different USB port on the back of the PC ( not the convenience ports on the front ). If that does not resolve the issue, you may want to try a USB add-on card if there is an expansion slot available on the motherboard. 73 Lloyd - N9LB -Original Message- From: FlexRadio [mailto:flexradio-boun...@flex-radio.biz]On Behalf Of w...@reagan.com Sent: Thursday, January 01, 2015 2:50 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] freeze up with a 1500 Set up a 1500 and Iam having trouble with freeze up of the display.The freeze happens about every 2 minutes,lasts about 3 seconds,then back to operation every thing on power sdr works as it should while no in a freeze state. the setup Iam using is: cpmputer - I5 ,windows 7 64 bit pro. 6 gb of ram. the usage shows 12.6 cpu use, the buffer is set at 512. 1500 is the following: sn# 1010-003 {old 1500} firmware is 0.53.10 when freeze happens cpu goes to 21.

Both are a 28 MHz. input. After first making sure that 10 meters was open and I was hearing signals, I plugged the antenna into the transverter port but could hear nothing. Ok, maybe the transverter port has a pretty low sensitivity and needs more RF, as it would get from any transverter. So, then with the dummy load plugged into the transverter port, I tried transmitting while listening on a separate receiver. I heard nothing. Yes, it's only a few milliwatts, but I would think I would be able to rear it.

[Flexradio] The new 472-479 kHz band - Technical Info
All, While the 1 watt to 5 watt power seems small, it really isn't because the specification is Effective Radiated Power. An efficient dipole antenna at this frequency would be about 1000 feet long, a 1/4 wave vertical would be over 500 feet tall. If you are running a 60 foot vertical ( requiring a huge matching network ), your efficiency would only be a few percent, therefore your transmitter power output would be somewhere around 100 watts. That is still very low communications power, but quite suitable for CW and some digital modes over 100's of miles - maybe more. I plan to gear up for it and be ready to go on the first day operation becomes legal. Yes I'll be using my FLEX-5000. Transmitting will probably require some form of low frequency transverter. Receiving might just require filtering and possibly a pre-amp. I'm looking forward to exploring a whole new band! 73 Lloyd - N9LB Message: 3 Date: Wed, 15 Feb 2012 12:55:14 -0800 From: Robert Costa, KB6QXM kb6...@yahoo.com To: Stephen Victor victo...@yahoo.com, flexradio@flex-radio.biz flexradio@flex-radio.biz Subject: Re: [Flexradio] The new 472-479 kHz band Message-ID: 648839.89845...@smtp217.mail.gq1.yahoo.com Content-Type: text/plain; charset=utf-8 1 watt maximum EIRP.

[Flexradio] How can I put a RX only antenna with a preamp on RX1? - Warning!
Hi ZacK! Be very carefull when doing this! I burned out my receiver input when trying this. In the current software, there is no relay disconnect of the external receiver input when you are transmitting ( when you split RX and TX paths ). Any transmitted RF that is picked up by the receive antenna gets fed directly into the receiver! I suggest you get an outboard front end protector or a very fast relay that disconnects the receiver input when transmitting. Hope that prevents you and others from experiencing some major grief! 73 Lloyd - N9LB Message: 8 Date: Tue, 14 Feb 2012 00:32:05 + (UTC) From: vtnn...@comcast.net To: Flex Radio flexradio@flex-radio.biz Subject: [Flexradio] How can I put a RX only antenna with a preamp on RX1?
