Re: Question: Which Analog Sony SRF Walkman Would You Rate the Best ULR?

Hi Dave,

<<<   Apologies for reviving a rather old thread.   >>>  

Not at all-- a lot of us enjoy tinkering with the high-performing Sony analog receivers (which actually got our Ultralight radio group started, about 10 years ago).

<<<   Recently, I purchased another SRF-59, aligned it, and mailed it to a friend to show him how good the performance of such a small AM radio can be, Then last week, on a whim, I purchased a NIB SRF-39 - the regular black model. After alignment, it performs well, but is not quite as hot as my SRF-59. No amount of re-tweaking can change that.    >>>

The regular black SRF-39 model is somewhat of a rare item in comparison to the SRF-39FP "Prison Radio," which was widely purchased and used by our Ultralight radio group from 2008-2010. I personally aligned about 15 of those models, and sent them to DXers in Canada (who were unable to purchase them off of eBay, due to shipping restrictions imposed by the seller). As far as I know the circuitry of the SRF-59 and SRF-39 models is identical, although the SRF-39 (and the SRF-39FP) use somewhat higher quality components which are designed to provide increased longevity (especially the variable cap, which typically develops the "scratchy tuner" issue in the SRF-59 after about two years of heavy usage).

<<<   No amount of re-tweaking can change that. The audio on the SRF-59 seems just a bit less bassy and a bit more pronounced at the high end, and more suited to copying weak stations. RF-wise, it's a tiny bit more sensitive too. I listen to local low power TIS stations at the top and bottom of the band to verify this. I'm wondering whether this is simply a case of unit to unit variation, or if there were any circuit differences between the SRF-39 and later SRF-49 and SRF-59 models. I'm tempted to purchase a number of them in order to find out, but am uncertain whether I'm really that committed!   >>>

If you have performed the recommended loopstick and variable cap trimmer alignment on the black SRF-39 and find that it is still inferior to the SRF-59 in AM sensitivity, then you most likely have a "dud" model with some type of inferior component(s), possible related to age deterioration. My own experience with the straight SRF-39 is very limited-- I purchased and aligned a single model, which ended up working as well as the SRF-39FP's. Most likely if you purchase and align a different one, your experience will be the same, Dave. Good luck!

Sony 2010 Antenna & Comparison? 

Hi

A) Has anyone done or know of comparisons of the Sony ICF 2010/2001D and current, modern, high-end Portable Radios. 

B) Antenna Rotation:

I have two super, IMHO,  Antenna ensembles for Sale Direct or on eBay for 2010's/2001d's as well as other Portable Radios. 

 A  C.Crane Twin Coil Medium Wave Antenna mounted piggyback on an HDTV /VHF Yagi Antenna/Rotator with or without a 25' Remote Installation Kit.  

The Twin Coil for MEDIUM WAVE for DXing and Rotating Nulling; the Yagi; for the AIR BAND and/or a Scanner Radio.  The TwinCoil Remote Control uses a 9 volt Battery or a wall wart power module   

I am using a unique setup on my 8th floor Balcony a larger TV Antenna Rotator The Twin Coil attached to the middle of two foot PVC pipe mast and the Yagi Rotator mounted above at the top of the mast so I can rotate each antenna separately

C.Crane Justice AM Antenna (Sangean) Plus 25 ' Remote Installation Kit  

Recommend piggyback on  Low-Cost HDTV-VHF Antenna/Rotator from eBay or Amazon 

With the Remote Kit, you can set the C. Crane AM Antenna Element closer to a window or even outside, away from the noise and interference, and dramatically improve reception on weak AM stations in brick, stucco, or metal-sided homes.


The Twin Coil Ferrite® AM Antenna is ideal for boosting most AM radio reception problems. No matter what kind of radio you're using, the antenna will reduce 90% of nighttime fade out, and help reduce static and distortion. The antenna can also double the signal strength of any weak station during the day.


The antenna was designed to work with everything from portable radios to home stereos with wire antenna terminals. The Twin Coil's wireless ferrite stick works on radios that don't have antenna connectors.


The antenna element is capable of pulling in a clean signal some distance from your radio. It then send the signal to your radio and overriding the static. This feature alone can make it the ideal AM antenna because there is no other way to get a clean signal. It has the highest gain of any commercial AM antenna.


The antenna element has directional characteristics. By rotating the antenna element in a window or outside you can improve the signal strength. As with any AM Antenna, you may need to take the time to experiment to find the best location.


Twin Coil Ferrite AM Antenna - AM radio is filled with interesting music and talk radio shows, but it's reception leaves much to be desired. Thankfully you can do something about that, by picking up this twin coil ferrite antenna. It doubles your daytime AM reception range, dramatically reduces nighttime fade out, and cleans up the heavy static and distortion. Doubles Daytime Reception Include - Tuner control, Antenna element, Ferrite stick with 1/8 inch Mono to RCA connector patch cord, RCA Female Patchcord to two bare wire ends, AC adapter, 5 ft connection cable Dramatically Reduces Nighttime Fade Out Helps Eliminate Heavy Static & Distortion Tuner Size - 3.3 (w) x 4.3 (h) x 2 (d) Antenna Size - 8.5 (w) x 2.5 (h) x 1.3 (d)

Re: SONY replies

If you want a radio which meets the ULR size requirement, the P26 does and the P36 appears to also when I measure mine. If you want the most sensitive of the 5 so far in the series the ICF-506 and ICF-19 seem the same. See RadioJayAllen's review On his wonderful site.
When I call them a series, it is because they all act uniquely the same when tuning stations on both AM and FM and they all have two LED indicators which work the same. A green one which stays on until the battery is quite weak and a red one which lights on reasonably strong stations. All 5 can be over loaded by RFI desensitizing them. To get the best DXing, be in an electrically quiet spot.- FARMERIK

Re: SONY replies

In a quick midday station count here, I found little difference between the ICF-P26 and P 36. The P36 is laid out horizontally and has lots of room for a longer ferrite. I coupled both to a large tuned ferrite loop, and the internal ferrite on the P36 is along the wide top of the case, and the P26 couples best along the narrow top of its case. The ICF-306 is noticably better and the ICF 506 and ICF-19 much better still at hearing more midday MW  stations.  - Rik

@ farmerik

I was using the manufacturer's specs. So its good by actual measure. I might grab one for giggles... see below

@radiojay

Yup, its crazy, F-38 model that went for $25+$3 Shipping is selling used for $50-60 and "new" for $200+. I have a pair of MDR-E828 earbuds... WOW $50 without the wind-up case. I think they cost $10+Tax.

The little ICF-P26 is not a bad pocket radio but it's too bad that it is less good than its long-time predecessor ICF-S10MKII which was available for well over a decade...maybe two decades, for around $10 but since its close out is now selling for way to much money...I've seen it close to $100 which is crazy.

Hi Paul- Nice to see you post. Did you measure a P36? Factory dimensions include the space in the back below the folded whip antenna. Not including the whip, I measure the case at  5&1/16th X 2 & 5/8th X 1&5/16th inches. Metric is just under 13 cm X 6.7 cm X 3.3 cm. - FARMERIK

747 kHz JOIB, barely audible to poor talking at 1145-1146.
774 kHz JOUB, barely audible talk at 1111; poor man and woman talking at 1117, peaking to fair signal strength at 1118 and 1123 before fading out at 1124.

I just checked into the 4 sets... the P36 is too large at 24+ cubic inches. But the P26 should be OK.

ION: very few new stations here, and those are 300 mi. or less. Canadian AM stations are much fewer in number, and my log is getting filled with (off). Been using the Dirt-Cheap-DSP (VT-111/V-111) with exposed ferrite bar, and a Tecsun loop. The R-9012 actually has a better battery-life than the R911/WRX-911 running about 480 hours continuous. A Tecsun loop is used for that one, and gets the big guns very well at night. The batteries that were installed on Sep. 11, should make it to Oct. 1 or 2.

As for non-ULDX, the Sangean-405 is quite adept at getting HF/AM-BCB by fiddling with the buttons. And the SONY icf-38 table radio is a nice set for $25US.
