Re: [IRCA] SRF-59 Alignment Procedure / TRF?
Interesting idea, but... Don't the SRF-59 and the SRF-M37V use the same IC (CXD1129AN)? The M37V is digitally tuned, and I can't imagine how you would implement a TRF circuit easily on a digitally tuned radio The SRF-59 does probably enjoy a tuned front end though, like most analog tuned radios, which is probably the secret to its better selectivity. On Dec 23, 2007 8:52 PM, Fred Schroyer [EMAIL PROTECTED] wrote: Let me toss out a really dumb question: since no one seems to be able to determine the IF of the SRF-59, could it be that it has no IF?

I've looked through online user manuals/instructions several times recently while shopping for electronics goodies. The product descriptions are often vague as to an item's true capabilities, but most manuals do a reasonably OK job at telling what it can or can't do.

[IRCA] Vast selectivity improvement for my SRF-M37V
This is for you experimenters out there that are complaining about the poor selectivity of the Sony SRF-M37V Walkman mighty-mite ultralight. It turns out that the SRF-M37V does not use the same chip as the SRF-59. I don't know where I ever got the idea that it did. I took my SRF-M37V apart and there is a TA737A5 at its heart. Of course, I couldn't find a datasheet anywhere for it. I guess it's a Toshiba part, though. Anyway, there is a small 450 kHz ceramic filter on the circuit card next to the main chip, which I unsoldered and replaced with a SFP450I ceramic filter from a dead DX-440 that I had laying around. The results were simply staggering! I can now receive the very weak KABR on 1500 kHz, despite the fact that my local KRSN is right next door on 1490! Impossible to do on my car radio, even!. For even more selectivity, I might have tried to use the narrower SFR450K from the same DX-440, but it's a little bigger, and wasn't sure it would fit, but the filter I used gives great selectivity. Taking the radio apart isn't too hard. After removing the four screws, the case pops right apart, without using fingernails, etc. There are two circuit boards inside, one for the keyboard/microcontroller, and the other for all the analog stuff. Yoiu have to unsolder on red wire to get the two to unfold from each other. Then you have to unsolder a couple spots on a copper foil shield which is covering the TA737A5 in order to get to the solder pads for the ceramic filter, which is marked 50J. Remove the the filter and clean out the holes. The new filter has to be laid on its side, and small wires run from it's pins to the holes where the old fiter was (no, it's not a drop-in replacement!). AFter you fold the two circuit boards back together, it's in there nice and cozy, and won;t be going anywhere. If you're worried about movement weakening and breaking your wires, I guess you could dab some RTV under the new filter to hold it in place, but I saw no need for that. NOW I have a sensitive, selective little DX monster that can switch to 9kHz tuning!

Re: [IRCA] Drinking the Kool-Aid, Jumping on the Couch
The M37V does indeed suffer from images when in the presence of strong RF. That's a problem common to most digitally tuned single conversion radios, because they lack tuned front ends which most analog tuned radios have. Today I took the unit and parked about a hundred yards from the antenna of my local KRSN 1490, which is running 640 watts. Strong image on 590 kHz (but it could be nulled into oblivion!) The image went away after I moved about a mile on down the road. The next strongest signal is from KSWV 810 in Santa Fe. While I was at the KRSN tower site, I checked for mixing products at 1490-810=680 kHz and heard nothing. OK, so maybe KSWV is just too far away to cause intermod with KRSN. Fine with me! Images and intermod could likely be dealt with by using the radio in conjunction with a tuned loop. That's something I haven't tried yet, though. In order to test the intermod better, I'll have to go to Santa Fe where there are 2 or 3 radio stations sharing a tower. If I park near it, that should bring out any intermod products. I'm lucky, I guess, that I don't live near any powerful stations. The local is several miles away from where I live so it doesn't bother me too much. At home, I notice no images anywhere on the band.

Elsewhere we learned that E1XM was being retained and the E1-without-XM was being discontinued because it would compete too close in price to the Sat750 that's due out any day now. And now it's the E1XM being axed and the XM-less version being kept/ Which is it? I agree though, who needs XM on a DXing receiver?

Re: [IRCA] M37V
The SFP series is 4 elements, the SFR series is 6 elements. The 6 element filter has steeper skirts, so is preferred, but may be a bit more expensive. The suffix letter indicates the 6 dB bandwidth. Filters scavenged from a DX440/ATS803A were the SFP450I and SFR450K. The SFP450I works great. I think it is a 6 kHz bandwidth filter. The SFR450K is better suited for SSB, as it is very selective, but leaves the audio quite muffled sounding in AM mode. The DX389/ATS909 has SFP450I and SFR450J filters in it. I haven't tried the SFR450J yet, but I suspect it would be just about ideal. It gives good selectivity without mufffling the audio too badly in AM mode on the Sangean radios, anyway Also, none of these are drop in replacements for the stock filter on the M37V, so they have to be jury-riged into the unit.

Re: [IRCA] Definition of the Unlimited Class of Ultralight Radio
Excellent! I like those limits. On Feb 11, 2008 9:55 AM, John H. Bryant [EMAIL PROTECTED] wrote: The Definitions Committee was called into action to more precisely define the erh, ah, limits of the Unlimited Class of Ultralight Radios for the purposes of the Firsts and Records List and the upcoming DX Sprint. Some very creative folks had even thought of using the ULr simply to tune the IF of a communications receiver and have that mega-buck receiver do the heavy lifting (or some such.) That is obviously not what we had in mind when we founded a Class that would encourage modification and supplementation of Ultralights So, after quite a bit of work, the Committee adopted the attached paragraph. I think that they did a great job of balancing the desire to have broad latitude for experimentation while also preserving the essential quality of an Ultralight receiver. I've adopted the paragraph for purposes of the List and will place a file at DXer.ca that defines both Barefoot and Unlimited Classes for all to see. Unlimited Class is any UL radio as defined and recognized by the committee with any of the following changes or additions: Internal modifications relating to BPF or IF filter replacement or improvement and replacement of resistors and capacitors in the audio processing section are permitted and encouraged. Peripheral accessories such as preamps, external antennas, amplified or passive, dsp or analog filters, Q-multiplier, antenna couplers, tuners, phasers or other matching devices may be used. The incoming signal must first enter the ferrite bar antenna of the UL, or the ferrite bar may be bypassed and signal fed into the RF and IF stages via the input points of the bypassed ferrite antenna, being processed solely through the complete circuitry of the UL (excepting the ferrite bar antenna if desired.) The purpose and spirit of this rule is to use all of the internal circuitry of the UL. Other than at the antenna input where the signal input may be pre-amplified, through use of tuned circuits, RF amplifiers and Q-multipliers, no active device may be inserted into the circuitry. This disallows heterodyning or frequency conversion devices where by the Ultralight is used solely as an IF amplifier, fixed or tunable. This rule does not prevent the attachment of a digital frequency readout device. John B.

Fascinating. Does this loopstick have just an antenna coil, or does it also have a center-tapped oscillator coil on it? I had pondered using the loopstick from my DX440 (which is 5 inches long by about a quarter inch diameter) on my SRF-M37V, but the M37V loopstick has 5 wires coming off it, where the DX440's loopstick has only 2.

The theory of proportional replacement (described in the SPR article) was followed again, and a larger-proportion copy of the tiny stock 2 loopstick was created by surgically altering the S5's coil arrangement, yielding a Digital Frankenstein with sensitivity apparently fully up to the SPR/ IC-2010 level. It is rumored that this tiny terror may haunt the environs of Grayland, and other ocean beaches this year. Unfortunately, the mega-loopsticks from the S5 are no longer commercially available in the USA, but they are common in Japanese parts units, as noted in the SPR article. Further experiments are currently underway with production ferrite bars and Litz wire, in hope of creating loopsticks approaching the sensitivity level of this experimental unit. For ULR DXers looking for sensitivity to compete with any portable on the planet, the concept is no longer science fiction... it is a reality!

[IRCA] KRSN DX Test this weekend
Just to remind you all, my local graveyarder, KRSN 1490 will run inventory inserts consisting of phonetic voice IDs, morse code IDs and tone sweeps early on Sunday morning. The test will run at 0100, 0200 and 0300 MST on Nov 26 for ten minutes each time. This will be tough. KRSN has a short antenna (folded monopole, about 80' tall) and is limited to 640 Watts by their STA. Email reports are preferred. Include a recording if at all possible, otherwise give exacting detail... Email to [EMAIL PROTECTED] Snailmail to KRSN AM 1490, 145 Central Park Square, Los Alamos, NM 87544 I will be handling the QSL cards...

Re: [IRCA] carriers on 1609 and 1611 mixing for het on 1609, 1610, and 1611
The two carriers on either side of the main carrier at 1610 are exactly what you would expect from a transmitter broadcasting a single test tone. These aren't really separate carriers, but sidebands resulting from the test tone being modulated onto the carrier. Remember, when you amplitude modulate a continuous wave, you get sidebands whose frequncies are (carrier freq + audio freq) and (carrier freq - audio freq). If the only audio you are modulating onto the 1610 kHz carrier is a 1 kHz tone, then the side bands will be continuous waves (kinda like carriers) at 1609 and 1611 kHz. OK, I suppose that it's *possible* that someone is transmitting three separate carriers at 1609, 1610 and 1611, but it's much more likely that it's someone transmitting a 1 kHz test tone modulated onto 1610 kHz. Bob Young wrote: That's exactly what I'm getting also, I believe this mystery tone is a het from these two carriers, they are both 1khz from 1610 and give the same tone on all three frequencies. I also get this same het note from 1521 Saudi Arabia mixing with WWKB 1520. I believe both carriers are from the same source also as they both fade at the same time and are of the same signal strength. I can null out the tone on all three carriers also with the phaser, it is easier on the 600 with the crystal phaser which eliminates hetorodynes without phasing.
