Hi Michael, <<< Gary, How well does external inductive coupling to the internal ferrite work with the CC-Skywave or similarly inaccessible radios? >>> The stock Skywave and other internally-crammed Ul

<<< Excellent job Gary, a real testament to your technical skills and tenacity. There is no shortage of wax on the original loopstick. >>> Thanks, Chris. The Skywave never was designed for easy modifi

Transplanting a 7.5" replacement loopstick into an ultra-crammed C.Crane Skywave Ultralight is one of the most technically challenging modifications in the hobby, and certainly not recommended for beg

<<< Thanks for this very interesting post. I can't see the images for some reason either in my email or on groups.io. I am anxious to take a look at the radios. Any ideas? >>> Yes, David. Here are the

The C.Crane Skywave Ultralight portable is extremely crammed, with the loopstick Litz wire connection points on the circuit board in the worst possible place for a "Supercharging" Loopstick transplant

Hi Rich, The contact information for Ming is contained in his message below. received about a month ago. f your Ultralight Radio Group members would be interested in ordering the R40C1 ferrite rods or

Although the new Radiwow R-108 seems to be a quality control nightmare from the warranty-shirking manufacturer, if you are lucky enough to purchase a decent unit on eBay (or of you happen to have Navy

<<< Maybe some feedback should be sent to the Chinese engineers so they can maybe sort these issues out. C Crane Skywave had similar problems with their first production run with whine and other issue

The Radiwow R-108 is a new, very compact Chinese-made AM-FM-LW-SW-AIR Ultralight radio which has recently become available to North American purchasers on eBay (such as this listing at $49.98, includi

Hi Guys, Sorry about the Groups.io software deleting the photos in my posts. Even for me, my photos usually only stay visible in the posts for about 18 hours, them Groups.io deletes them. The solution

Michael, I think that those links were posted in more than one message. The Radiwow R-108 disassembly links are posted below RF Circuit Board https://dreamcrafts.box.com/s/456oocxphu0uytkz8i9trfdhb067

Thanks Remy, <<< I have never used or even seen a C.Crane radio but still, if the D-808 is a copy of the C.Crane and judging from it, “technical innovations” doesn't seem to mean improvement. I find t

Hi Max, <<< Is the section of the ferrite rod rectangular mm 8x4 or round Radius 8 with to flatten sides? >>> The R-108 loopstick's ferrite rod is completely rectangular, with the flat (8mm wide side)

<<< What do you mean exactly? What "technical innovations"? I find the D-808 a very good receiver, but I don't know of any technical innovations. 73, Rémy. >>> Remy, I'm not sure that you understood t

For those who weren't aware of the fact, XHDATA and Radiwow are actually the same Chinese company, which has specialized in wholesale design appropriation of the C.Crane Skywave SSB's technical innova

I'm not sure who you are asking, Max, but the inductance of the PL-380 stock loopstick is about 280 uH, and the "Supercharged" loopstick version is about 350 uH. The internal Si4734 DSP chip is design

Gary, Since the original PL-380's were introduced in 2009 the Tecsun company has attempted to increase profits by significantly reducing the DSP chip shielding in all post 2011-models, resulting in th

Around late 2015 a wacky concept was conceived to shrink the FSL antenna down to an airport-friendly size, thereby allowing DXers to exploit its awesome compact performance during exotic overseas trav
