[Flexradio] Curry Power
ZS6AVM Wrote: Is this Curry Power, or Curry Powder J They call it the WonderRadio, I guess one has to wonder if it works J Ignoring my comments above, I guess that apart from re-engineering, or perhaps even back engineering, they have come up with wot is hopefully a working SDR.

[Flexradio] DM 780
Tom, I recently started using the DM 780 software too. Look to (from memory) the tools menu in HRD 4 and the IP server selection, then activate it for the two to communicate. Once you start this then DM 780 will read and control the frequency for HRD and the SDR radio. It can be set to start when opening the software. Once used the band buttons in DM 780 will be useful to select frequencies such as for modes BPSK31. 73, Jay, AA4FL Date: Wed, 18 Jun 2008 05:12:33 -0500 From: TOM BLACKWELL (nt) [EMAIL PROTECTED] Subject: [Flexradio] Ham Radio DeLuxe and DM 780 To: Flex reflector flexradio@flex-radio.biz Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=ISO-8859-1; format=flowed I have Ham Radio DeLuxe and DM 780, ver. 4, working except the frequency window on DM 780 shows closed.

Re: [Flexradio] Indian SDR Rig
Hi All; I am totally saddened that Flexradio decided to drop the low end SDR-1000, possibly man power issues, not sure, but quite certain that both the 1000 5000 could have lived under the same roof leaving us all with a choice, and known quality of support. I honestly believe Flex dropped the ball, and broke a NA Line of SRD's that would have survived with great rewards...usually called Business Growth. Shipping from India /or Germany to going to offset any apparent savings I'm afraid, that combined with any required service that may be needed down the road is certainly going to keep me away. I waited and looked for months to find a 1000 that will be used exclusively on EME, and no way could I justify a 5000 for a 28Mhz IF as Dana has mentioned. I still believe there is room for a peeled down 1w version of the 5000 for this market, what the demand would be in the weak signal area, EME Otherwise I have no Idea, but would have loved to have seen at least the 1000 continued here in NA. I am 70 years old and perhaps should not care, but I do. ALSO because of NAFTA (North America Free Tirade Act) anything Imported from outside of NA is subject to Duty and Excise Taxes that amount to approx 25%, at least here in Canada.

I was saddened by the discontinuation of the 1W SDR-1000 though I understand it from FRS's business standpoint. For my VHF+ work I just can't justify dropping about 3K on a 5000a to be used as a 10m IF. And for $479 the Indian board sure beats the $641 for an unknown condition 1W SDR-1000 that sold yesterday on eBay. I think there is a hole that needs to be filled with a low cost SDR radio and since FRS decided to abandon that market why should they or anyone be upset that someone else moved in?

Re: [Flexradio] Indian SDR Rig
What was a cutting edge a year ago in now considered low end by some for reasons I cannot understand. Be that as it may, I agree with Flex's decision to discontinue the SDR1000 because it makes perfect sense for them to do so. An SDR1000 equipped with a 100 watt amp, internal tuner, Hosa cable set and the additional gound loop eliminators, line isolators, hum destroyers, ferrite beads, rf chokes, pre amps and decent sound card like the edriol FA66 cost about $400 shy of the baseline Flex 5000A. The main difference is with a Flex 5000A you won't have to deal with all the problems that can be associated with the myriad of connections that make the SDR1000 work. How many times have you heard of folks radios not working because of defective cables or poor connections? It happens all the time. The company has decided to place everything in 1 box inculding a vastly superior soundcard connected by a single firewire cable. By doing this, the amount of potential tech support requests should drop significantly and the result is a more polished product that delivers a pleasant out of box experience. It also give the Flex folks more time to improve their product. For those of you who still want to purchase an SDR1000 there are occasionally ads on ebay, eham and on this reflector for used models that are surprisingly low in price that may be able to fulfill your needs. I'm keeping my eyes open for a second SDR1000 because of it's low cost and its superior receiver. Also note that since the SDR1000 has no knobs there will be practically no wear and tear on the unit. A dead fan should be easy to replace and I don't mind dealing with all the wires for an amateur transceiver that blows just about every radio out there away! B'lee dat!

Doesn't have to actually have the audio interface on board, if one took an off the shelf interface widget and just soldered permanent cables to it and the RF unit and put them both in a box. (That's what I did with the SDR1000s I was using at work.. just soldered cables to the pads where the miniphone jacks used to be...) Or, a cookbook integration of HPSDR stuff might do? Realistically, it's going to be a moderately pricey board.. in the $1000 range, I'd guess. ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/

Realistically, it's going to be a moderately pricey board.. in the $1000 range, I'd guess. That's sort of the right direction (aside from the fact that a lot of it is speculative designs at the present time). However, it's missing what I think are a couple of key aspects: 1) you have to be able to buy the package in one shot, and not have any cobbling together or just recompile the linux kernel sorts of steps. N5BF, an old Amsat hand, and I have discussed this at some length, with respect to things like satellite ground stations. The SDR1K had the advantage over almost ALL the other SDRs out there of being a one-stop-shop. You could get your hardware, including all the cables and interfaces, AND a functional piece of software from one place and get it up and running in a few hours. 2) It's not PowerSDR compatible. So you're stuck with the software problem... there's no simple plug and play solution that's compatible with the uwsdr hardware. (the uwsdr software doesn't exist yet) Linrad is really receive only (as Leif's page says, Linrad also has a transmitter albeit in a very early development stage.).. on the other hand, I think that having the digital interface being Ethernet is a great idea. Heck, if someone would make a high performance audio A/D, D/A to Ethernet streaming box/board that can feed out timestamped audio sample streams, that would be great. (Maybe someone does.. I'm not following that particular market very carefully..) And, if someone wrote a ethernet audio stream to windows audio device virtual cable, then you could use PowerSDR. (yes, the Janus+Ozy sort of does the same thing, but USB isn't Ethernet.. it's master/slave) (and yes, if someone were to not just do Ethernet, but IEEE-1588 as well, that would be even better..) Don't get me wrong... there's a lot of cool stuff out there for SDRs, but very little of it is truly plug and play without a fair amount of handholding. It's aimed more at experimentally minded folks who want to work in the guts of the system or who are early adopters. If I were a microwave experimenter on 24 GHz and up, I'd want a back end that I didn't have to think about too much. I'd have enough troubles with my RF front ends and antennas to fully occupy my time. ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
Re: [Flexradio] Indian SDR Rig
Jim, That's exactly why I think there is some positive feedback on the Indian rig. Add the Atlas/Ozy/Janus combo to it and you are close to the $1000 board you mentioned. If FRS or someone else offered a 5000 series style (integrated sound card) 1W board for $1000 I'd buy it. I've been looking for a 1W rig at a reasonable price for some time. Mike (KM0T) had a great deal that was gone by the time I had a chance to investigate. This kind of SDR1K replacement may just be the ticket or a step in the right direction. I'm sure FRS has looked at that market and by appearances (no 1W radio) decided it was not viable for them. Hopefully as more and more people move into SDR they we re-evaluate this decision. With guys like Mike, Philip and others who blazed the trail by using their SDR-1000 for VHF+ (and kicking everyones rears in the contests) I think in coming years you will see an increased demand for a SDR based IF rig just to stay competitive.

There might also be regulatory issues to consider. The F5K, by virtue of it's (closed source) firmware controlled DDS, etc., is an easier sell in terms of not being a scanner, not radiating outside ham bands, etc. It's one thing to sell a bare board which has these capabilities, especially if it's three boards that YOU stack together. It's another to sell it in an enclosure with antenna connectors, etc. So perhaps, a specialized IF rig might be the way to go. You could optimize the filters in the DDS output for the somewhat narrower tuning range. That is, you don't need DC-60 MHz.. a nice 10 MHz span around 30 MHz or 144 MHz could do quite well.. you could also use a different clock strategy... Rather than rely on the DDS to generate the quadrature clocks (and incurring the hassle of matched low pass filters and comparators), you could generate 4x the desired frequency and do a divide by 4 to generate the switching signals for the QSD and QSE. And, have some useful logic for sequencing and band selection of external converters as well (although, perhaps, that's straying into too many functions in one box territory..hey, why not put a az/el rotator controller, and a KC tracker emulator and a chiming clock to tell you when it's lunch time and, and, and...)
