[Elecraft] OT-well sort of:Short Wave Receivers...Suggestions???
Hi Gang, I'm thinking of buying a short wave receiver like a Grundig or something, and have been looking at them on the web. What I have in mind is a very small, pocket sized rig, 2 AA cells for power... Now, I have found a couple of models, but they don't have a BFO for CW, and don't do SSB either, AM only. Now, I'd like to find one that does it all from 100 KHz to 30 MHz...any suggestions... Been working on the R-390A. The First Mixer died (6C4), so decided to go through the entire rig this weekend and replace all of the known problem components. Turned out great! Anyway, I really enjoyed listening to the BBC World Service among other stations while I was letting the rig burn in today. I had forgotten how much I used to like to listen to SW Stations...Plus, you get a different perspective on World events and such, so that's why I'm looking for a portable. Would be nice to have all the modes though...Might be Pie in the Sky, but maybe not...Seems like a good idea for an Elecraft product! A portable general coverage (100KHz-30MHz) receiver with R-390A performance in your pocket ;-) Come on Wayne... 73 Trev - K6ESE ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

It won't fit into my pants pocket, but is perfect for a coat-sized pocket. I take it on walks daily. For power it takes 4 AA batteries or will accept a 6vdc source. It has a BFO, AM Sync, RF attenuator, and more memory than I can use.

Most of the digital radios that will cover the frequencies and have the facilities you require are greedy on battery consumption or at least were up to a few years back. I lived in Saudi Arabia for 20+ years and SW radio for the last 13 years was the prime way of getting news. Lived in an area where the nearest black top road was 100km away and no terrestial television, electric power or telephones outside our camp. We did not get any satellite TV until the mid 1990's, so SW radio was the only way of keeping track of the outside world. I started with a Sony 2001 in 1981 and that was still OK when I retired in 2002. Also had the later 2001D which also has the SSB/CW facilities you need, though again greedy on battery consumption, which meant use on a AC power supply was essential. A popular radio was the Sony 7600D used by many expats at the time which was somewhat better in terms of battery life. Lost track of what is available today, but for SSB/CW use Sony was always at the top of the pile in the past. Maybe the battery consumption problem has been cracked with more recent technology, but the only way at that time was for reasonable battery life was to use an analog radio and most of these did not have the SSB/CW features nor the frequency coverage required.

[Elecraft] pocket portable swl reciever
Hello Trev, In the past I've also suggested Elecraft produce a General Coverage shortwave reciever kimaybe someday they will. In the meantime I've aquired a Degen 1102 (matches my K2 serial number, 1102). Read my (and other) product reviews on eham.net. (http://www.eham.net/reviews/detail/4226). It is almost full coverage, starts at 3 mhz and goes up to 30 mhz (plus 70 - 108 mhz FM) so no coverage of 160m and/or no coverage below the am broadcast band. Other than that it is a great little radio for the price (approx $62 including shipping from China), the least expensive SSB capable radio I know of. I got mine here : http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemcategory=15051item=5737941199rd=1 If the link doesn't work just search Degen on ebay. If you must have 150khz to 30 mhz (with SSB) then the Grundig YB400 is a good choice, although not really pocket size and is a battery hog. I have a YB400 and an 1102 and find I rarely use the YB400 since getting the 1102, which is smaller, lighter than YB400, and uses only 3 AAs (1102 comes with 3 NI-MH rechargeables and wall wart charger) The charging circuit built into the radio automatically tapers charge rate as necessary. And so far, anything I can hear with the YB400, I can hear with the 1102.

[Elecraft] OT: Noise Reduction?
Hello elecrafters, i am looking for a device to reduce/eliminate the noise of a 2m ssb-receiver. What the circuit should do: Reduce (or eliminate) the noise of the rx when no signal is present, like a squelch, but much faster. It should be an analog device, not a dsp-device. It should be external ( e.g. input from the receiverŽs headphone jack). Background: A friend of mine runs a transponder 144Mhz ssb - 432Mhz fm. The fun with ssb input and fm output is that 2 or more persons can have a conference like on the telephone. There is no interference (whistles when 2 signals present) like on fm , because there is no carrier in ssb. We would like to eliminate or reduce the noise in the pauses. I heard that musicians use a so called ŽnoisegateŽ, but could not find any circuit on the web. Any ideas anyone?

Re: [Elecraft] OT-well sort of:Short Wave Receivers...Suggestions???
Trev, There is a good site for researching such things at Radio Nederland http://www2.rnw.nl/rnw/en/features/media/productreviews/rx_index.html I'm not sure there is one that meets your small need and does SSB/CW. I travel overseas with a Sony ICF-SW100, which is small (two AA batteries), synthesised and sophisiticated. Using a passive reel-type antenna (I think there is such a device available from Radio Shack, though mine was made by Sangean), it seems plenty sensitive for SWBC. That is my main use, so I can listen to news and such when in remote locations (Patagonia in two weeks) without carrying a larger radio. Before that I had a less-capable Sony ICF SW-1, but it died 5-6 years ago. In a larger format the Sony 7600GR does SSB/CW. Uses four AAs. I take it camping but not overseas. Judging from the size and features, a kit of this sophisication and size would have lots of SMT devices, and be gnarly to design and build. 73, Phil Trev - K6ESE wrote: Hi Gang, What I have in mind is a very small, pocket sized rig, 2 AA cells for power...

Most of the digital radios that will cover the frequencies and have the facilities you require are greedy on battery consumption or at least were up to a few years back. Yes, they do suck down the batteries. For my Sony SW-100 I carry Lithium AAs. They last longer than alkalines and are about half the mass. I also carry a small analog receiver of Chinese origin (Kaito WRX911) as a backup: It runs forever on two Alkaline AAs (price was $35 or so, one-tenth the price of the SW-100). It is strictly AM only, since my purpose is to find English SWBC to listen to in the evening (I'm always trekking during the day on these trips) Since my use is sporadic (two weeks in Greece in May, two weeks in Chile this month), the battery count does not get too high. 73, Phil ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KPA 100 resistance checks
I've built the KPA 100 up to the alignment and installation steps and made the resistance checks at J3+ and Q1 and Q2 collectors (all of which are supposed to be greater than 10k). The instructions state that the J3+ resistance may initially read 0 because a large electrolytic must charge up and that it may take 20 seconds for the reading to stabilize. My readings at J3+ and the Q1 collector never stabilize above 10k - they start at 0, pop up to a value above 10k, then start decreasing eventually ending around 1-2k. Is this okay?

Re: [Elecraft] OT-well sort of:Short Wave Receivers...Suggestions???
I believe the reel antenna is active with a preamp powered from SW-100 depending on which switch position the freq range is set for. It is a pretty impressive radio for the size. FM stereo at the headphone jack, fixed level audio output jack for recording. Slow tuning rate for SSB/CW. And synchronous detetection with a choice of either USB or LSB keeps fading to a minimum. Built-in alarm clock too and memory presets. Set on top of each other the package is slightly bigger than a pack cigarettes. Fits nicely into a shirt pocket. - Original Message - From: Phil Wheeler [EMAIL PROTECTED] To: Trev - K6ESE [EMAIL PROTECTED] Cc: Elecraft Mailing List elecraft@mailman.qth.net; [EMAIL PROTECTED] Sent: Monday, December 13, 2004 10:29 AM Subject: Re: [Elecraft] OT-well sort of:Short Wave Receivers...Suggestions???

But it, too, takes batteries. I have one but do not use it. My active antenna is an extendable whip, not a reel. They also make a larger active loop antenna that I don't have. Packs up small, I believe. Can be ordered from AES. I find the passive reel model quite adequate for SWBC, since the radio is very sensitive. But the more exotic antennas could be useful if staying in a large metallic hotel, since they can be remoted in a window of some such place. 73, Phil ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I've owned several compact portable SSB-capable Sony radios in the 7600-series over the last 22 years and I consider all of them to be excellent performers for this class of radio. The ICF-7600GR is the latest and best of the lot, though it's been out for a few years. Independent reviews have always been lauditory, and unlike the closest competing Grundig product, it has synchronous AM reception. It's just a little too large to be considered pocket-sized, yet with that size come a respectable speaker. At about $180, it is IMO still a great value.

[Elecraft] Mods, mods, mods for #1107
Yesterday I put the SWR mod in my KPA100 for my K2 #1107 which was purchased on 3-29-2000. No problems and the rig worked fine as usual after the mod. I got to thinking that it seems like I have been doing mods for four years and it must have cost me a fortune. I got out my invoices (I have never thrown ANYTHING away) and ran a total on my mods and the original cost of the K2 and all modules and updates. I have a K2 with a KPA100, a SSB module, a 160 meter module, a noise blanker and a DSP module. Todays price for these is a total of $1344.00. I then ran a total on my K2 with new crystals, PPL mod, 2nd filter mod. BFO mod, shield mod, firmware upgrades, etc., etc. and got a total of $1345.00. So over four years of adding mods (I admit some didn't cost anything) I had to spend a whole dollar more than I could have bought the same end product today. Of course I had four years of use of an outstanding tranceiver and the enjoyment of making the mods and dealing with a company that furnishes free online documentation and service second to none. I think I got my money's worth!! Allen KA5N ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K2, Mounting RFC11
Ben, Just put the wires in the holes, push it flat against the bottom of the board, snug the wires on top and solder. It WILL stay in place - not real tight, but certainly good enough - there are a lot of K2s out there that have RFC11 mounted just that way and I have seen no problem reports about it yet. 73, Don W3FPR - Original Message - Ok, I found a couple of messages in the files about RFC11, but nothing decisive. The manual says to mount it horizontally on the bottom of the board, but the holes are almost on opposite sides of the toroid. This would mean routing the wires around the side of the toroid to get to the mounting holes, and wouldn't make it too awful secure I wouldn't think. How did all of you you mount your RFC11? Pictures? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

AGC - was [Elecraft] OT-Preserving CW memories
I was at VO2AAA in Labrador City for CQ WW CW with K2/100 #850 and an AL-1200. We were next to a residential area with a very high line noise and precipitation static. On 80 and 160 meters with the AF gain about 3/4 way up and riding the RF gain and DSP with noise reduction made some of the second third tier stations copyable. Sometimes you have to be really fast on reducing the RF gain to save your ears! I don't really like the sound that I get out of my K2 with the DSP, but when you are digging stations out of the noise the NR and the DSP filter #1 really helped. The K2 as the run station was good for about 3000 Q's, the mult station for a couple hundred. And 3.4M points. Think I remember working a couple calls from this list! 73HankK8DD At 12/11/2004 07:45 PM, W3FPR - Don Wilhelm wrote: Ron and all, Are you aware that reducing the RF gain will reduce the AGC action as well. Folks who want to try it may be surprised how well copy can be made under QRM conditions with the AF gain at full and the overall gain controlled by the RF gain. With this technique, the residual AGC provides some 'limiting' protection for the ears while allowing one to dig for really weak signals - this is applicable at any bandwidth, but more so for wider ones. 73, Don W3FPR - Original Message - To this day I still prefer a wide filter, even with moderate QRM. With my K2 on CW, I use the SSB filter more than any other. I love being able to keep track of what's going on around the frequency I'm using. The trick of course, is to turn off the AGC so stronger signals in the passband won't depress the receiver gain. One of these days I'll add a hard limiter to protect my ears. The dynamic range of the K2 allows really huge peaks to come through without the AGC. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
