Thanks Richard, it has taken some time and a few attempts but finally it is working for me how I want.

Portable Ultralight Radio DXing Kit 2020 - An Update

I have made another change to my "portable ultralight radio dxing kit". After buidling my radio testing stand, I decided I wanted to try and add a stand to this case, the idea being that it would make it more portable. The results are below:

I have used a TCF and a 2 ft air wound box loop (MTM Scientific) together and I had the most fun ever daytime DXing!  I might be one of the people Jay mentioned.  I sent him a recording of me phasing out one station, then another on 570 AM.  Both stations abt. 150 miles from me - one due south, one north east at 30 degrees.  Using the 2 antennas I could fully null one station or 90% null the other.  If not nulling, you can also get amplification. There were plenty of spots on the dial where nothing turned into a copyable something.  A 250 watt daytimer 90 miles away on 840 is an example.  The hitch?  None really although if your AM radio has an AM antenna jack you will get more predictable and repeatable results.  I used a Redsun/Kaito RP2100 which allowed overriding the internal looopstick. Second best (more fiddly) option is to couple the TCF to your radio via the TCF loopstick thingy ma dingy, finding the best possible spot for signal transfer.  "Best possible" is important for best phasing/amplification results with the two antennas down line.  Tape the TCF inductive transducer (technically, that is what it is) to your radio so it doesn't wiggle.  Then negotiate your signal hunting with the TCF and the loop, or whatever your second antenna is and be prepared to be amazed.

I haven't tried this (and can't right now because most of my stuff is packed for an upcoming move), but a few people have written to me describing notable results using a Twin Coil antenna with a second antenna and physically arranging the Twin Coil elements relative to the second antenna to introduce regeneration. With regeneration you can achieve razor sharp selectivity and huge gain just below the point of oscillation. It is tricky to do even with antennas which have regeneration built-in - when you do it using two antennas, one amplified, it is even trickier but it can  be done.

FSL+TCF? #ultralightdx

Al Short
 

Has anyone else had any luck or experience combing an FSL with a C.Crane's Twin Coil Ferrite antenna?
I place the pickup (small bar) nearby the 3.5" FSL and find that I can get some notable results.  While there does seem to be some gain, I am most impressed by the directionality/nulling I am able to achieve by rotating the large bar in conjuction with the FSL. Placement of the  small coil near the FSL appears to be quite touchy and there needs to be considerable separation from the large bar to avoid feedback effects.
My current passion is in the "graveyard" and with this setup and my Xhdata 808 (highly recommended) I have made many new catches.  I would love to hear from anyone else with experience with this setup.

Miller  report- Just as it arrived the crystal tuner got 20-30 stations at night on the West BOG which included WWVA-470 miles, WTAM-440 miles and WJR-565 miles. Audio is suburb, there is some fading with out an AVC at night too. Day time locals have even better audio. One pair of stations only 10 KHz. apart can not be completely separated, but I could favor either one. I plan to send it into the shop later for more modern fixed caps and to have other diodes compared for sensitivity. It really hears more than I expected as it is. -FARMERIK

Re: Looking for Paul S / Ferrite in SE CT- FARMERIK

The NAB (formerly referred to as NARTB) equalization is very severe and only slightly different than the RIAA Phono eq...neither is suitable for a nominally "flat" input signal and will give a huge bass boost and treble cut compared with a "flat" mic input. But have you already determined that a Line level input is not sensitive enough for this application? If not, I would try that first.

     Last April during a trip to Hong Kong I was highly motivated to chase long range AM-DX, but there was a bizarre "Catch 22" problem-- all of the buildings had nasty indoor RFI, while almost all of the outdoor areas were overcrowded, and unsuitable for setting up an elevated 5 inch "Frequent Flyer" FSL antenna. For the entire week I pushed a 7.5 inch loopstick CC Skywave to the absolute limit, taking it on daytime DX trips to Macau and HK's plunging Cape D'Aguilar, as well as shoving it outside a 12th floor security window to escape the indoor RFI. For the first 5 days "long range DX" was a laughable term-- my farthest catch was 693-Bangladesh, at about 1,500 miles.
 
     Finally I sacrificed some sleep and shoved the souped-up Ultralight outside the security window prior to sunrise, and somehow managed to track down 1431-Radio Sawa (Djibouti), 1413-BBC (Oman), 1413-Vesti FM (Moldova) and 1548-TWR (Moldova) on the 7.5" loopstick. The performance of the souped-up Ultralight was thrilling, but the harsh lessons of the Hong Kong trip had already been taken to heart. A fully portable, hand held DXing combo was needed which could provide more gain than a 7.5" loopstick, but which could be easily carried anywhere in a backpack, and which would not attract too much unwanted attention on crowded public beaches. In addition, it would need to routinely pass through TSA inspections at airports, and need to be capable of deployment outside of windows (with a PVC support system) in order to escape interior RFI.
 
     Only one type of hand held antenna could satisfy all of these requirements--- a portable radio + tuned FSL combination attached to a compact PVC frame. Since the TSA-friendly FSL's are all relatively lightweight, combining them with a compact portable radio on a common PVC frame is well within reason for hand held capability. Such a DXing combo would be the master of convenience-- it can track down MW-DX (with decent gain) while being held in the hands, placed on a picnic table, placed on a 5' PVC base, or even elevated to a higher level. The combo's PVC frame can be supported (with attachments) to provide decent DXing gain outside of an apartment window to escape indoor RFI. And even for those who usually have no interest in live DXing, it can check transoceanic propagation and even go after exotic targets prior to broadband antenna setup.
 
     Current experimentation has resulted in four different FSL sizes for combo frames (see photos)-- a 3 inch model (10 Russian surplus 100mm bars), a 3.5 inch model (13 bars), a 4 inch model (16 bars) and the standard 5 inch "frequent Flyer" model (20 bars). The latter FSL is the same model which was used a couple of months ago in Hawaii, tracking down AM-DX from all continents except Europe during sunrise and sunset sessions. The option of having one of these high gain FSL's in a go-anywhere, hand-held combo is pretty thrilling. Future experimentation will use some of the new R40C1 ferrite to make up another series of compact FSL's for this project, as well as drafting a few of the 3 inch "Baby FSL's" with Russian surplus 125mm ferrite rods into the effort. It's looking like an exciting experimental year is coming!

Some of my tube amps have tape head inputs too. I can't remember what the NAB equalization is like for those. Perhaps you know.
Most all with mag phono inputs have equalization choices to try. [RIAA, Lon, EUR, Columbia etc.]
