Hi Do any of you have any experience with the C.Crane Twin Coil Magnetic Loop Antenna? How does it compare with the Super Loops used for ultralightdx? Is it "legal" for ultralightdx? 73 de Jordan

Hi Rick, It's great to hear from you again. <<< The encoder shaft on my CCrane SWP broke about that long ago and it sat gathering dust all this time on the workbench shelf. I happened to find

Hi Gary, That is a great review you did and I can tell I've missed a lot in 4 to 5 years. The encoder shaft on my CCrane SWP broke about that long ago and it sat gathering dust all

Hans: The PL-310ET is a good radio. However it's not quite as good as its predecessor the PL-310. The ETM function is nice to have, something the earlier model lacked. I've heard several Asian and

Gary's reviews are great. The newer PL-310 ET has the ETM feature I use to compare antennas and check band conditions by how many stations it finds. Each ULR DSP set is slightly different, so study

Hi Hans, The Tecsun PL-310 was one of 5 Ultralight radios thoroughly reviewed in the 2015 Ultralight Radio Shootout article, posted at

Hi everybody.. At this moment I have the Tecsun PL680, an excellent receiver and my idea is to buy the Tecsun PL-310et Any experiences here in this group with this receiver? Hans

Gary thanks for your reply 73

paul thanks for your reply. Based on the schematic http://static.panoramio.com/photos/large/110849142.jpg it is ok about the coils... however what makes me worry is the fact that the modification

Hi I don't think one can build a ferrite loop that will cover the HF Band(s). My intentions are to bypass the twin coil ferrite rod assembly, and use the Varactor/Amplifier with a larger Loop. One or

So modding a twin-coil to HF... you do realize the patent involves a ferrite rod antenna phasing. So my question is if you plan to use ferrite bar antennas to tune in the HF band, what mixture of

I have owned all 3 at various times. First was the WRX911 (still made today) that does not need the mod, but is a bit more expensive. The R911 Tecsun just lost the slide-switch function after 9 years,

in order to be more precise with my question above .. i ask if the SW bands calibration (with the printed frequencies dial) will get ruined, if i do the 1700khz expansion mod that needs to touch the

Hello everyone I have a question about the MW frequency coverage expansion from 1602 to 1710khz for the chinese tecsun R911 (aka wrx911) R912 and R9012... as it is described in the

If you plan to change the frequency range of the block diagram in the patent, there are at least 5 components that must be examined for frequency response, if not changed somehow. These are the three

Hi Thanks for the timely response. I am thinking of replacing the twin coil ferrite and using the electronics with a new Magnetic Loop,ferrite based but more likely a 1 or two turn 48" diameter loop.
