Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver
Thanks for a good answer, Ed. No, I was not asking for someone to design and market a 20 - 500 KHz transverter (for me). I would rather do it myself, but lack the time at present.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
Well... If it won't get much cheaper than basic K3, what's the point then? I'd rather have K3 with sub-receiver, all the filters I need (or, rather, want) AND with all the features Elecraft wizards put into its firmware. An alternative is to force them to write, test and support two different versions of firmware for two rigs, and at the end both projects can suffer. In other words, I like Elecraft rigs for their excellency in what they do, not for the brand name.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
Hi Don I was referring to a direct sampling SDR black box. I am sure a direct sampling receiver with the Elecraft brand name would be a top seller. Lyle probably has prototypes on his workbench! I am also sure that a DUC transmitter from Elecraft would also be a popular product. Direct sampling and DUC transmitters are in all our futures. 73 John --- On Thu, 3/17/11, Don Wilhelm wrote: > From: Don Wilhelm > Subject: Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver. > To: "juergen" > Cc: elecraft@mailman.qth.net > Date: Thursday, March 17, 2011, 7:09 PM > John, > > The K3 is an SDR.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
Maybe if someone started working on a receive converter for 20 to 500 KHz, with TX ability on 470 to 500, the firmware would come for it? Could test it with any IF on which the K3 can receive. The K3 can already be operated as a transverter IF at 1 mW for the 500 KHz range, albeit with a few restrictions. Too bad I don't have the time here. But a lot of Elecraft projects get started because someone from outside the company thought them up. If there is enough pent up demand, somebody will work on this. The K3 would make a !great! SWL receiver, but it isn't very well known outside the amateur community (my guess). 73, matt W6NIA On Thu, 17 Mar 2011 21:01:31 -0700 (PDT), you wrote: >My AOR AR-7030+ was over $3000 when I bought it in 2000, and it was worth >every penny. > >There are other receivers by Ten-Tec and a few others that are more than that. > Some are sold to serious SWLs but I imagine most go to the government.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
My AOR AR-7030+ was over $3000 when I bought it in 2000, and it was worth every penny. There are other receivers by Ten-Tec and a few others that are more than that. Some are sold to serious SWLs but I imagine most go to the government. I think most serious listeners these days are using SDRs like the Perseus The K3 would need mediumwave and longwave (down to 100 kHz) coverage to be of interest to me and the listeners I hang out with. 73, Ken Alexander VE3HLS --- On Thu, 3/17/11, Alan Bloom wrote: > From: Alan Bloom > Subject: Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver. > To: elecraft...@yahoogroups.com, elecraft@mailman.qth.net > Date: Thursday, March 17, 2011, 4:14 PM > It would be a pretty expensive > shortwave receiver: > > K3/10 $1500 > KBPF3 $140 > - > $1640 > > You'd save some by eliminating the 10W PA but have to add > some for the > 8-pole 6 kHz or 13 Khz filter to replace the stock 5-pole > 2.7 kHz > filter.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
John, The K3 is an SDR. It does not depend on an external computer to support its operation, but by all proper definitions of an SDR, the K3 qualifies. I am not certain what your "true SDR" means. If your definition of an SDR is one that is a "black box" that requires a computer to be a fully functional device or one that requires a spectrum and waterfall display, then I believe your definition is limited. The K3 has the SDR computer built-in, and the downloadable firmware can alter its functions and characteristics drastically - that is the basic definition of an SDR. I believe you are looking at the presentation aspects of other SDR radios that depend on an external computer for support, and that is not the essentials of an SDR - an SDR is a radio that can be altered by installling different firmware - a pure and simple definition, and the K3 does qualify for that. If you want the latest on computer assisted SDR designs, I suggest you look into the Softrock-40 group on Yahoo, there is a lot of good activity, and the hardware kits are available at reasonable prices. 73, Don W3FPR On 3/17/2011 9:37 PM, juergen wrote: > I would like to see a true SDR receiver from Elecraft.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
I'm honestly puzzled. What would that KR3 have the your existing K3 doesn't?? The others wouldn't need to buy the 100 watt amp and you could sell your amp if you didn't want it.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
The concept of KR3 receiver makes excellent sense. The ability to have true diversity receiving in one box has long been sought. I have been a swl for over 40 years and have far more receivers than transceivers and often run multiple receivers. Most of my listening outside of the ham bands is utility listening and often have two receivers, with different antennas, tuned to the same frequency to improve copy. Granted this leaves something to be desired but it does help. Until I got my K3 this was the only option for me at least. The cost of a fully loaded KR3 would about $2500.00 in kit form and would be well worth it to me. There many groups of serious SWL's who would be interested in such a receiver.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
I doubt there would be savings in removing the 10W PA, but it could be disabled by either running in TX TEST all the time, or by putting a jumper on the ACC TX INH line and setting the correct state in the menu. 73, Don W3FPR On 3/17/2011 4:14 PM, Alan Bloom wrote: > It would be a pretty expensive shortwave receiver: > > K3/10 $1500 > KBPF3 $140 > - > $1640 > > You'd save some by eliminating the 10W PA but have to add some for the > 8-pole 6 kHz or 13 Khz filter to replace the stock 5-pole 2.7 kHz > filter.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
I'm pretty sure that there are people out there who have indeed spent that kind of money on SWL receivers, but it seems to me that it would be far more prudent for one of them to just buy the bare minimum K3 as is. If you (or you heirs) ever wanted to sell it, there is a much larger market for a top end ham transceiver than for a top end SWL receiver. Even if the 10w PA could be easily added later, I don't see where much money would be saved ... the economics for either Elecraft or the user just don't make much sense to me. Then again, how something is marketed can make a lot of difference in whether people buy it or not. Lots of folks want an appliance and will sometimes even pay extra for a box that looks like it was tailored specifically for their wants/needs even if the hard content is less. There are lots of examples of that sort of thing in the consumer world. 73, Dave AB7E On 3/17/2011 1:14 PM, Alan Bloom wrote: > It would be a pretty expensive shortwave receiver: > > K3/10 $1500 > KBPF3 $140 > - > $1640 > > You'd save some by eliminating the 10W PA but have to add some for the > 8-pole 6 kHz or 13 Khz filter to replace the stock 5-pole 2.7 kHz > filter.

Ten-Tec's is $4250...

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
I suspect there's a larger market there than you might think, at that price. TenTec RX-340 runs a bit over US$ 4K. NRD 545 (discontinued) go on the used market for $1.3K. Both of those receivers are much larger physically than the K3, so there may be some resistance in paying more per cubic inch for a K3. Also, these receiver tune down to 30 KHz or lower, so a built in up-converter for the K3/0, along the lines of the the 2 meter down converter, might be required as an option.

Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver.
It would be a pretty expensive shortwave receiver: K3/10 $1500 KBPF3 $140 - $1640 You'd save some by eliminating the 10W PA but have to add some for the 8-pole 6 kHz or 13 Khz filter to replace the stock 5-pole 2.7 kHz filter. Would people be willing to spend well over $1500 for the best SWL receiver on the market?
