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!

Thanks Jay
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.]

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

If the output is too low for a Line level input I would try a Mic input rather than a Phono input as the phono;s RIAA equalization will give very unflat frequency response.

Thanks for listening to the MP3, Paul, and it's no big deal that this 918 kHz Oz station remains unidentified. Australia from the Cook Islands isn't exactly exotic DX :-)

I just thought that with 918-2XL having gone silent on AM, I had better ask for opinions before the station's programs fade from the memory of the local AM-DXers.

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

Thanks Paul.

I saw your email before I saw your message here.

I will use a microphone or phono input on a tube Hi-Fi amp made in the 1950's. I have a collection of them to try. It is mentioned in the Miller literature.

Also I expect the 20 Kc. wide selectivity will be too wide, and would want to change the caps to the values recommended by Miller to increase sensitivity and narrow selectivity some what.

I will be choosing from four sharply directional BOGs so adjacent 'channels' will be less common on the dial, and signal strength from the antennas will be high.

They connect into the house via co-ax so low impedance compared to just an inverted L wire directly connected. I may need a matching transformer at the Miller?

I have a couple of Ultralight radios which I have posted reviews for:

https://ultralightradiodxing.blogspot.com/2020/01/review-teac-pr130-portable-amfm-radio.html

I have recently noticed a local store has a ultralight radio for $19.95 which has a digital display, this is something I am planning on purchasing to test it out.

Miller made these pretty good in the day. More modern individual components would make it better using ceramic caps and tighter tolerances.

For a start the manual suggests using a 15pF cap on top of both L1 and L2, this is advisable, 18pF looks OK if two are handy. I'm not sure what the Audio Output is intended to be, but I presume 2K headsets of the day (50's). These are coil-wound (inductive type) headphones. Tough to find in new condition and working well.

Modding this with my low power amp requires two crystal earphones in parallel (a great idea no one talked about in the modern day) to be directly driven by the transistor. This would not need any part of the Miller circuit from the diode to the right, substituting the amp. I'll email the small diagram of the whole radio I built, you would not need my "front end". In your case, the 68pF cap that is input cap can to be lowered to 56 or 47pF. Some trade off of final volume for select-ivity, but OK to use 68pF (not any higher though).

Re: Looking for analog receiver suggestions (not necessarily modern nor ultralight)

DEFINATELY take advantage of Jay Allen reviews and excellent information! And since he posts here, he may answer questions after you read his reviews-


https://radiojayallen.com/am-portables-mega-shootout-2019-update/

Also read his article about the RCA globetrotter portables for AM DXing which are my favorite classic analog portable for DXing which is not an expensive model because of excellent selectivity.

In his reviews you will see a number of currant Sangean AM FM portables DX very well. I have a PR-D7 modified to add a antenna jack by PK loops AU. When connected to an outside antenna, it beats the other Sangeans coupled with any external coil I have to the same antenna. If you can wind a coil on the ferrite inside one of the other Sangeans Jay recommends, it should be even better if you use external antennas. -FARMERIK

Barefoot just go with Jays recommendations.

I connected the mla30 with an external 2 meter x 2 meter loop, and it works nicely! And what a signal!

I don't have any info for you on this but just wanted to comment that this looks like an interesting and fairly unique device. Good luck with it!

Jay


Re: 2019 Shootout?

Rik
 

Back to ULR's, I did buy one of those MLA-30 amplified untuned loops which ARE very compact and light weight, mainly to use with the PL-360 series of radios.  When you unplug the stock antenna you can plug in modified ones for the chip to tune, but they don't like tuned loops. The MLA-30 is not tuned. It adds a few more stations during an ETM scan. I just checked around 9:30 PM local time and the stock ferrite for one of my PL-360 locks on 47 AM stations while the MLA-30 makes it lock on 55 AM stations. That is not a lot more, however the MLA-30 really boosts WEAK AM stations so it should help ID new stations. Actually my guess is the PL-360 WANTS a coil to tune. It does much better on my few SONY and Sangean models with 1/8th antenna jacks which work on MW.  Probably the correct air core or ferrite coupler and  a plug in antenna in the PL-360 may be better. That of course would work with all the other ULRs.- FARMERIK

If I remember correctly, you used to DX with simple one active device radios. I just won a Miller Hi Fi crystal AM tuner on Ebay, and wondered if the germanium crystal could be replaced with something more sensitive or a detector/amp solid state device I could power with a battery. I don't want to permanently modify the antique tuner. Here is a page with links-

Yes, I know it is not an ULR, but could be built small enough.

All are welcome to answer this, not just Paul S.


918-Australian UnID in the Cook Islands-- 2XL in Cooma?

Gary DeBock
 

918 2XL Cooma Commercial 2k NSW
918 4VL Charleville Commercial 2k QLD

During a wild trip to Aitutaki in the Cook Islands in April of 2018 this very wild recording on 918 kHz was made at 1658 UTC on April 12th, with a 7.5" loopstick CC Skywave and 5" FSL antenna. It starts off with the Cambodian National Anthem from 918-RNK, the infamous "Cuckoo Clock" time pips at 1:41 (a mix of the time pips from Shandong in China, and RNZ from New Plymouth and Timaru) and an Australian UnID at near S9 level from 4:05 to 4:45. There is a musical into starting at 4:05 and finally a "Midnight, with Merv Starr" program identification at 4:36 into the recording. Does anybody know if this program was on 918-2XL overnight (or on 4VL, for that matter)? Any assistance from Oz would be appreciated-- thanks!  https://dreamcrafts.box.com/s/qams92h5ktn7ki93u3qlvbzvyl3y8rru
