[Flexradio] Flex-3000: RF output power reduction after a short period of operation

Hi all My Flex-3000 has developed an RF output power problem. After transmitting with full drive (Drive = 100) for a couple of minutes in a CW QSO the RF output drops back from more than 100W to around 70W. This occurs on all bands and whether transmitting into a dummy load or a matched

Re: [Flexradio] Flex 5K and VAC

I had some problems with overflow/underflow and audible glitches using VAC 4.13 with my Flex-3000 radio. The problems disappeared after I reverted to VAC 4.11. 73, Brian VK3MI -- Message: 5 Date: Wed, 02 Apr 2014 19:02:33 -0400 From: David Edwards w...@verizon.net

Re: [Flexradio] Good laptop for Flex 3000?

Hi Tim Several models of HP notebook have ExpressCard ports. I'm using an HP ProBook 6570b and a Firewire ExpressCard with my Flex-3000. The note book also has on board FireWire port (JMicron controller) but unfortunately it is not compatible with the radio. 73, Brian VK3MI ZL1AZE

Re: [Flexradio] Portable power supply for Flex-3000?

Thanks for all the suggestions about portable switched mode power supplies. I'll have a closer look at the Alinco DM-330MV, Powerwerx SPS-30DM and Samlex SEC-1235 options. 73, Brian VK3MI ZL1AZE ___ FlexRadio Systems Mailing List

[Flexradio] Portable power supply for Flex-3000?

Hi all I'm looking for a small and lightweight AC power supply to power my Flex-3000 radio when travelling. I'm thinking of a small switch mode supply but it will need to be very quiet from an RF noise perspective. Any recommendations for a power supply in this category? Thanks and 73

[Flexradio] WriteLog modification for Flex-3000 SO2V operation

Hi All WriteLog version 11.10 has just been released at http://writelog.com/downloads/writelog-versions . This version includes a modification to the K3 rig driver so that it can be used with the Flex-3000 radio for SO2V (single operator two VFO) operation. I expect the modification will

[Flexradio] Noise problem when tuning Flex 3000

I'm running a Flex 3000 radio with PowerSDR 2.5.3. When tuning across the 160M band (in any mode) the received noise floor toggles between a normal (lower) level and an erroneous (higher) level. Steps as small as 1 Hz can toggle the noise floor. The erroneous level is approximately 6 dB

Re: [Flexradio] Waterfall memory for each band

Hi Tim Thanks for the hint - we look forward to seeing this feature in PowerSDR v2.5.x :-) It would also be helpful if this future version of PowerSDR could expand the waterfall parameters to offer a faster refresh rate - ideally to something like the rate used in CW skimmer. I find the

Re: [Flexradio] FlexRadio Digest, Vol 86, Issue 15

Hi Mike I'm using an HP 6550B ProBook (i7 processor) which seems to work OK with my Flex 3000 radio, I note that the more recent 6560b ProBook also has a Firewire interface. 73, Brian VK3MI ZL1AZE -- Date: Fri, 15 Jun 2012 16:22:27 +0100 From: Michael Ruttenberg

Sounds good Gerald - digital starting at the antenna connector is the way to go! All the best for the 18 May event. 73 Brian VK3MI ZL1AZE -Original Message- From: Gerald Youngblood Sent: Tuesday, May 15, 2012 9:38 PM To: FlexRadio List Subject: [Flexradio] Imagine digital starting

Re: [Flexradio] Laptops Flex Radios

Hi Kermit I have recently acquired a Flex 3000 and run it on an HP Probook 6550B laptop using the built in firewire port and 8 GB RAM. So far it seems to be working work fine. The only difficulty I have encountered is when running CW skimmer and the Flex 3000 on the same laptop. With this

Re: [Flexradio] FLEX-3000 FLUCTUATING CW OUTPUT POWER

Thanks to everyone for the comments. It does seem that the fluctuations in the output power meter readings are an artefact of the sampling/averaging process that drives the meter display. I will have a play with the multimeter options to see if there is a setting which provides a more

[Flexradio] FLEX-3000 FLUCTUATING CW OUTPUT POWER

I have recently acquired a new Flex-3000 radio (running SDR v2.2.3) and have been giving it a test drive into a dummy load. All seems well except that the output power reading on the TX meter fluctuates from about 70W to 105W when transmitting CW dots or dashes at 30 wpm and 100% drive. Is this
