This post was updated on .
I'm looking for a new general purpose HF receiver and have been disheartened by radios, including transceivers, currently available on the market for less than around $2K. Consequently, I would like to know if Elecraft plan to incorporate Synchronous AM detection?
I noticed the latest firmware update includes wider AM IF bandwidths. Can Elecraft disclose what these bandwidths are yet please? Thanks, Shane. |

The software being tested now brings the IF bandwidth up to 10 kHz if you have the FM filter installed, 6kHz if you have the AM filter installed. AF response in the 4-ish kHz range. AF response will eventually improve to around 5 kHz. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Thanks Llyle - I plan to buy a K3 once Synchronous AM is available and I think you'll capture a good part of the shortwave listener market then too. |

Lyle, with the improvements you've described, will the K3 be able to receive an IF bandwidth of 10KHz using synchronous AM?

In anticipation of my purchase I downloaded the K3's instruction manual. This manual states that Synchronous AM mode can be used. Can Elecraft please verify that the K3 does not yet receive in Synchronous AM mode? Do you expect to provide this functionality within the next 2 or 3 months, or is it a year or more away? Thanks again, Shane VK5ABQ |

Shane,
You could consider buying a used Drake R8 on eBay -- In my opinion it is a fantastic general coverage receiver with sync dedtection and great sound. You might be able to pick one up for about the cost of a K3 subreceiver option! 73 de Ken - N4OI / K1 <quote author="Shane White"> I'm looking for a new general purpose HF receiver and have been disheartened by radios, including transceivers, currently available on the market for less than around $2K.

I suspect it will be available in much less than a year. As I mentioned earlier, it is on the task list, but there are higher priority items on the list which must be completed first. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Thanks for the suggestion N4OI but the R8 was released 16 years ago. I'd like to take advantage of some modern receiver design.

Ken,
I'm going to say what a lot of people are thinking but to polite to express. I like your suggestion. After all the prime focus of the K3 design is amateur band, CW,SSB, and digital modes. Having high performance for these modes is its selling point. Asking it to "do everything" on all frequencies detracts from efforts to optimize its primary functions. In almost 50 years, I've heard maybe 1 amateur FM station operating. Yeah, there may be a few more but it hardly constitutes a majority mode. Are there really so many ham AM ops? Sure people are free to buy anything they want. Their choice. However, what they do buy may not be optimum for their needs. I think Elecraft is doing an amazing job at meeting the needs of their owners. However, even they have limits. 73 de Brian/K3KO <quote author="N4OI"> Shane, You could consider buying a used Drake R8 on eBay -- In my opinion it is a fantastic general coverage receiver with sync dedtection and great sound.

The blindness of the HF only operator again? FM is absolutely a majority mode everywhere but HF, but to have only heard 1 FM signal in 50 years implies not attempt to progress beyond HF. FM is used all the time at VHF, though not for DX. That in Europe at least includes 6m and up. There is also limited activity at 10m. The K3 is an excellent transverter driver and that is the reason many of us bought one. Having FM capabilities is necessary for DXing at VHF and above. I am sure everyone aware that microwave rain scatter contacts are frequently easier to complete using FM than SSB or CW because of the dispersive effects of the mode. Then there are the FM satellites. AM is less used for transmission but very much used for SWL.

I agree with the diversity of usage of rigs. I'm guilty of being the
blind HF op who only uses CW and a bit of SSB, but I'm really interested in experiencing synchronous AM. I'd love to do some 10M FM just for fun. I'm sure there are others like me who, while focusing on one mode, are interested in dabbling in something new. So, is sync AM important? Yea, it is. It's part of the reason I bought a K3. So is 6 meters. - Keith N1AS - - K2 5411.ssb.100 - - K3 maybe today - -----Original Message----- From: Mike The blindness of the HF only operator again? _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I'll have to go along with K3KO; I tried to opine the same thought through
Nabble and it was never posted. Three of the most voracious modes, spectrum wise, are FM, AM, and most anything digital, in that order. Spectrum is and has been a premium for amateurs. It may be more so in the future. A relative few hams are users of the aforementioned modes. They appear to be the most frequent commenters on this reflector. Spectrum use is one issue. The other is making the K3 all things to all users. I personally want to see a great CW and SSB radio. If, with time, it can do more with other modes, great. I wish the FM/AM/digital folks would remember that there are two guys, one the code writer, who drive the K3 developement. Give them a break and lets ease up on the esoteric. My opinion. 73, Jim, K4ZMV ----- Original Message ----- From: "AD6XY - Mike" <[hidden email]> To: <[hidden email]> Sent: Friday, April 18, 2008 9:19 AM Subject: Re: [Elecraft] K3: Desired AM mode improvements > > > The blindness of the HF only operator again? > > FM is absolutely a majority mode everywhere but HF, but to have only heard > 1 > FM signal in 50 years implies not attempt to progress beyond HF. > > FM is used all the time at VHF, though not for DX.

And get the backlog down to almost "off the shelf" .......

Hi Brian,
There are many users of 10M and 6M FM and many repeaters on these bands ... even several here in Montana. (:-) AM also has many users, especially on 75M and 160M. 73!

I do not favor censorship on this reflector. These are only suggestions.
This hobby is not only for CW and SSB ops. The K3 developers can accept or disregard any or all suggestions on this reflector.

I for one am looking forward to AM synch on the K3. (or will be, once
I've gotten my K3...). As strange as it might sound, I wouldn't have ordered one if not for general coverage receive capability, so this feature is pretty important to me. That and CW are my "prime focus". I don't have a problem with waiting while the more popular features are developed. But the K3 is a software defined radio, with the promise that it WILL do nearly everything; or at least everything a Drake can do. Anyhow, I just wanted to add my vote for synchronous AM detection and wider b/w. Also, independent sideband selection would be nice as well.Thanks. 73, Drew AF2Z On Fri, 18 Apr 2008 05:57:34 -0700 (PDT), you wrote: > >Ken, > >I'm going to say what a lot of people are thinking but to polite to express. > >I like your suggestion.

I don't think any of us are "grumpin'" at Elecraft for not having
implemented sync-AM or FM yet. At least I know I'm sure not. I agree completely that they need to get the main stuff working first. CW, SSB, RX & TX performance, etc. But, Sync-AM and FM were part of the original plan and I for one don't want to see them fizzle away and not come to fruition. I have every confidence in Elecraft that they will work these issues in the right order, getting the important stuff done first. - Keith N1AS - - K2 5411.ssb.100 - - K3 maybe today - -----Original Message----- From: Jim Miller First things first.
