Re: New Design 3 inch (76mm) Baby FSL Antenna-- a Tiny Thriller

 

Wow. That sounds like an interesting idea. It looks to work well. I assume they are custom built? 


Grouping Stations

Hi all.

I am in the process of setting up some groups in my database, at this point I am grouping them by these types:
National (ABC)
Commercial
Racing
Community

This will be used for my next round of radio challenges. Any other suggestions?

Hi Frank,

I don't know if you have seen the 35 page major article linked below, but it features extremely detailed reviews of five popular DXing portables (with four of them "official" Ultralights)  https://dreamcrafts.box.com/s/8y6855bnfmy45rnk46mzr7hb4pwjz8u8

Thanks Paul,

As you may know, your 3" FSL antenna was actually the "movie star" in the video posted 2 years ago at the following link. Your model uses 125mm long ferrite rods, while the new model uses 100mm long ferrite rods. As it works out with the Ukrainian ferrite selling cartel, the shorter rods are significantly cheaper  New Design 3 Inch (76mm) Baby FSL Antenna Demo Video - YouTube

Hi Frank,

No wire connection is necessary between the radio and FSL antenna-- it uses inductive coupling.

The FSL antenna can dramatically boost up any radio signal received on a portable, once the FSL antenna is tuned to the same frequency as the radio. A detailed guide on using the FSL antenna is posted at  .FSL (Ferrite Sleeve Loop) Antenna Tuning Course - YouTube

Sounds like a real winner. I have used a couple of digital recorders in the past but nothing of late, I might need to look into getting another one.

Re: Audio Recording/Audio Recorder recommendations?

I used a Q3 tecsun recorder player with FM radio  for long time till i started my SdR
MY review
https://gadgets-zliangas.blogspot.com/2015/10/tecsun-q3-review.html
In contrast to the most of the above it is a simple model recording only in MP3 128/44 mode with steps of 1 hours if the recording lasts more 
ti has very good sound quality via earphones in MP3/WMA/WAW playback

ICR100 is also good with good sensitivity in MW/FM with slightly less bass in earphones Also good audio via the speakers. FM sensitivity is better than PL380 
The generated files are of type RECxx.mp3


1100kHz mais mais brazil

Zacharias Liangas
 
Edited

from my latest monitoring at https://wp.me/pcMZHt-4R here is a log that needs clarification

1110khz with presumed religious program with spiritual song at 1313z (coracao)  “mais mais brazil”  as motto , then a beat song . S20 or -37 dbm   Not real ID for much time except this motto
Does anyone here  know which is the station? As per my logs these 3 signals from that kiwi SDR seem to transmit very from  a very nearby point
Thanks!

I also use the DR-05X for quite some while, can only underline the good results. Besides this I had tested the Zoom H-1n which is also fine in recording but emitts a lot of RFI noise as the components are not shielded. Also fine any very small is the Olympus LS-P4 which I use with the radios from time to time but more in the office or when travelling. For simple recording purposes also useful is the Tecsun ICR-100 which adds another loadspeaker of decent quality. Good recording except from old radios with very small line our put levels. The Tecsun has no noise (RFI) as it is a simple usb recorder and no pulse recorder. The mp3 files of the Tecsun show no date/ time in case this important for you. Good luck!

Sony SRF-T615 availability?

Anybody know how to get a Sony SRF-T615? Mine died last week - I've had it over 10 years. Won't wake up any more. I checked the usual sources and couldn't find any for sale. Thoughts?

Re: Audio Recording/Audio Recorder recommendations?

Hi Jerry,

How does it do with a line in from your radio?  Great I imagine, as that is its primary purpose, I would guess?

But how is it recording a "live" source, like something in the room or a outdoor sound?  

Thanks a lot!

Re: Tecsun PL-368 Manual / Enhanced Convenient Tuning (ETM+)

Robert Conboy
 

What I find very annoying about the PL-330 is somewhere in the gain algorithm. Not sure if it’s the same thing you’re reporting as annoying soft-mute. There seems to be discreet steps of gain/attenuation without hysteresis, so the loudness often flutters rapidly at some medium to low signal levels, even if the signal strength is relatively steady.

If the DSP is lowering the audio gain when signal strength or SNR is below a threshold, then it’s soft-mute. But if the DSP is raising the IF gain (or its equivalent in software) when signal strength is below a threshold then it’s AGC.

Either will create the same rapid fluttering change in volume if gain/attenuation is in discreet steps and there is no hysteresis, because noise, being random, is constantly crossing above and below the threshold. If the time constant is around 1/10 of a second then the flutter rate may be in same neighborhood.

I think its a bug or something overlooked by their engineers and QC.
