Do we know the quality of the "vintage" Soviet ferrite? The date stamp suggests older production. I once had a transistor radio from the Soviet era. Sensitivity was poor - it worked better, with an

Hi Joachim, Congratulation on constructing your new FSL. That's a good size, probably about 165 mm coil diameter. And if you're hearing the noise level increase when you tune it, it must be resonating

Hello Joachim, Thanks for sharing the results of your first FSL project with us. Steve and Kevin may have their own comments, but I'll suggest a couple of tips. For covering the NDB band with an

Hello Frank, Thanks for your intererst in the Sony ICF-SW7600GR 7.5" loopstick modification. This project was designed (in July of 2008) to provide a very compact, sensitive SSB spotting receiver for

Hi, list! Yesterday I built my first FSL using a 150 mm dia. Styrofoam former, 23 ferrite bars, 100x20x3, permeability 400, 3 layers of bubble wrap and 55 turns of 100/44 litz wire = 1615 uH. I

Hello Gary, I am very interested in modifying my SW7600GR. Could you tell me what size litz wire you used and also approximately how many turns you used in modifyoing your Sw7600GR ? Appreciate any

Hi Kevin - Thanks for the reply. I am so green on radio surgery that I'm not even quite sure what the "trace" is. The wires coming from the pcb to the led? What do I test with? I have the service

Hi Brian: Have you tried testing the LED itself? Not sure if these burn out. Disconnecting the trace to the LED (to test the LED) would allow you to test if there is voltage coming to the LED as

Sorry you have had a problem. In my experience, the ultra-cheap pocket radios from China (under c. USD $20.) are extremely variable in quality (as one might expect). The Sony S10MK2 and SRF-59 and

Try returning a defective item to an Asian seller and then you will get burned. Sure the sellers claim you can return it. Just try to do so. Shipping rates are the same or higher than the cost of the

Hello, I did something funny. I made maps for all stations on a frequency, and also +/- 0.1 Mhz, and +/- 0.2 Mhz. Green: the freq itself. Dark red: +/- 0.1 Mhz Light red: +/- 0.2 Mhz You can click

Hi all, Conditions have been very poor for about a week. Even semi-local beacons were barely audible. Besides, with night time getting shorter, one has to say up late... not fair when you have to wake

Fairly decent LF conditions, finally got another new one. 279 heard. Steve NE Oregon PL-380 + FSL 256 TQK, KS 1001 Mi

"Let the buyer beware" should be the motto of eBay. To me "You ALWAYS get what you pay for" means expect to pay a premium for good products, not (IMHO) "The most expensive is always the best". I

I was reading a 2004 IRCA publication which included many articles written by names I have seen here, when I noticed an article 'Large Area Loop for High Noise Environments' by Glen Kippel. It is

That goes without saying...but how can this person have the gall to ask these prices? Can he possibly be getting people to buy?

Something less pretty but equally suitable could be rigged upwith a pair of lightweight headphones and a cheap, tiny FMradio. Michael UK

I was looking for a headphone am/fm set (mine just died). Can't believe that an e-bay seller thinks that he can get $500 or $1,000+ for some pedestrian offerings. Check this seller's store!
