Re: [Flexradio] VU5K Question
Im using the Flex 5000A on EME on 70cm & 23cm , 13 cm and it works perfect, and the panadapter is a nice thing. Im using Transverters from a friend of mine SM4DHN owner and constructor of LABETECH transverters, they where sold under the name Parabolic. a copule of years ago There might be some left!!! if you check with him. sm4...@labetech.se What i missout on the panadapter are the Continium mode that you could find on SDRIQ`s Spectravue swthats soo net to use when messuring moon noise and Sun noise. I asked the to get it implented almost a year ago but nothing so far :-( 73 de Lars SM4IVE www.sm4ive.com Thanks, Ron. I tried calling DEMI a couple of times over the last few weeks and got their recorder. I'll try again. FWIW I checked the 5K transverter port right up to 31.99 mHz, and it worked quite well. The output level was somewhat higher than I anticipated, but I'd rather have it too high than not high enough. :-) 73, Jim N7CXI On 12/18/2012 2:39 PM, Ronald G.

If the DEMI 432-28 transverter is equipped with the Apollo LO synthesizer option, the LO can easily be set as high as 409 MHz, giving 432 MHz –> 23 MHz, 435 –> 27, 440 –> 31, etc. By bringing a few wires outside the enclosure, the LO can be changed easily. The Apollo LO synthesizer is locked to an external 10 MHz source and the FLEX-5000 also has this option. The Apollo LO has options for LO = 402-409 MHz in 1 MHz steps. It may be possible for DEMI to provide a transverter that would cover the 440-450 MHz range.

Re: [Flexradio] VU5K Question
Robert You haven't mentioned anything about ground buses yet? Do you have you in place? Why do you think that you have to rewrite your microphone? What type of mic is it? Can you try another mic? Also, disconnect anything from the radio that you are currently not using? Is the computer ground strapped to the radio? Is the radio power supply plugged into the same power bar as the computer? Start simplifying things first and then add more bits. Don't blame the radio as many others have great success. We just need to sort out your environment.

Re: [Flexradio] VU5K Question
Terry, My situation for RF ingress is a lot worse. I have Ferrites on everything. I do not have anything on my dipole so I might be getting RF ingress from common mode currents. I also may have to rewire my microphone as I might be getting RF through my microphone. The RF ingress affects me on wave lengths above 40 meters. I can only use 80 and 40 with my Flex now.

Re: [Flexradio] VU5K Question
Robert I initially had some RF ingress issues, but I put ferrites on all audio and power lines, as well as microphone cables. I have no issues now and work the bands up to 70cm with no reports of any RF on my signal. I have some external digital processors, BHI, that I use as well, so there are lots of audio cables external to the Flex. I also use the Tokyo Hy-power 2m amplifier without RF issues. My main issue was with the fan noise of the VU5K, but I found by carefully balancing the audio and using the DExp control that I could keep the background noise out of my transmitted signal and I no longer get audio reports asking about the noise in the background. Having the panadapter when doing weak signal work is really nice, as these can be so easily missed.

Re: [Flexradio] VU5K Question
While not specifically applicable to the FLEX-5000 question, a write up of mine was just posted on the Flex KC “A Full-Duplex VHF-UHF Satellite System using FLEX radios” http://kc.flexradio.com/KnowledgebaseArticle50507.aspx This article deals with using two FLEX units, the 1500 and 3000, but most of it is applicable to the 5000 with the two receiver option. With respect to the bandwidth of the DEMI 432 transverters, they informed me that “The RF range of the transverter is about 430-440 MHz.” For the FLEX-5000 with PowerSDR v2.4.4, the high end filter switch point is 32 MHz. If the DEMI 432-28 transverter is equipped with the Apollo LO synthesizer option, the LO can easily be set as high as 409 MHz, giving 432 MHz –> 23 MHz, 435 –> 27, 440 –> 31, etc. By bringing a few wires outside the enclosure, the LO can be changed easily. The Apollo LO synthesizer is locked to an external 10 MHz source and the FLEX-5000 also has this option. The Apollo LO has options for LO = 402-409 MHz in 1 MHz steps. It may be possible for DEMI to provide a transverter that would cover the 440-450 MHz range.

Re: [Flexradio] VU5K Question
I think the issue may be that true VHF/UHF hounds want converters with "extreme" performance - noise figure, selectivity etc. It's tough or perhaps I should say expensive to get those things over wide frequency ranges. I live in a rural area, so a simple NE612 converter with a decent RF amp and a stable, low-noise local oscillator would be peachy. If I lived in Western Washington, though, the requirements would be different. If I did EME, that would up the ante again. Food for thought. 73, Jim N7CXI On 12/18/2012 2:02 PM, Robert Costa, KB6QXM wrote: I personally liked having the option of having transverters for the Flex. All mode, VHF/UHF.

Re: [Flexradio] VU5K Question
Dave As you know the VU5K is no longer in production, but there may still be some available from Flex. It is their intention to support existing units now in use, at least for a while. The only route left is to use external transverters. The 5000A is set up for this. Note, that if you get the VU5K installed you cannot use other 2m or 70cm transverters with the VU5K. I only found this out after purchasing a German Kuhne TR 144H +40 2m transverter. I have since purchased a Flex 1500 to use with the Kuhne transverter. There are several transverters available from Down East Microwave, SSB Electronic and others. Most of these transverters are designed for weak signal work and cover the lower portion of the band. Initially, I had some issues with the VU5K, but these seem to be resolved now. I have been able to tweak the setup to use the VU5K on weak signal work with success. Terry On 18/12/2012 16:19, H.
