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!

Re: 2019 Shootout?

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.

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

Re: Australian Stations - January 2020

Australian capital city stations like 873 Sydney 2GB, and 1116 Brisbane 4BC will be around a long time. This is because they attract older (maybe very old) listeners for mainly talk-back. These listeners however are on borrowed time, so who knows what will happen economically to stations like 2GB and 2UE when this older generation passes on. But current ratings surveys show that 873 2GB is the number one AM station in Sydney [1]

In view of the recent catastrophic Australian bushfires, it could be reasoned that high power ABC radio regional MW outlets are here to stay indefinitely. They provide an important PSA resource for mainly rural area listeners. High VHF band digital coverage is short-range and unreliable compared to medium wave.

The ACMA AM to FM conversions are only planned as an option for station management to decide. The ACMA cannot force AM stations to move. Existing AM stations have the option of not moving to FM. It all depends on various factors such as signal area coverage, population, transmitter fees, etc.

What do think the chances of the big stations like 2GB and 4BC etc going to FM in the next few years ? I was tuning around the Brisbane airspy server and the FM band certainly doesn't seem overly crowded so is this the case nationally I wonder ?

Paul,

The Digitech AR-1733 (and the identical Japanese market Elpa ER-C57WR) are actually predecessors to the C.Crane Skywave model (which was introduced late in 2014), made by the Redsun company in China. C.Crane used it as a starting point for the completely redesigned Skywave, since Redsun had already been C.Crane's manufacturer in China for an extended period. The CC Skywave does have some improvements over these earlier Redsun-manufactured models, as explained by Mike Schuster in his excellent review posted on Amazon, which is pasted below. Mike's Skywave review was written about a month before my own Skywave review in the 2015 Ultralight Radio Shootout.

Gary DeBock (in Puyallup, WA, USA)

Pasted from Mike's review of the CC Skywave on Amazon (December 2014) :
I'm surprised that, after all the buzz about this radio on hobbyist websites and blogs, nobody has posted about it here. So I'm giving a quick overview as I await my second Skywave Radio (having ordered the first one directly from CCrane and decided that this one is "keeper")

This is the official update to the well-regarded CCrane shortwave portable (SWP) which is still for sale; both having been sourced from Redsun in China. It is also a re-work of an intermediate Redsun model not sold in the US, but known in Australia as the Digitech AR-1733 and in Japan as the Elpa ER-C57WR.

The radio covers MW/SW/FM and the aircraft band (omitting LW that previous models covered). It appears to use DSP (digital signal processing) technology like many newer models sourced from Tecsun in China and sold under various brands including Kaito, Grundig, etc. Such radios achieve pretty exceptional performance using a minimum of electrical components because the SiLabs DSP chip does most of the traditional RF stuff right inside. However, all have suffered from various design or performance compromises including uneven sensitivity, unwanted noises, and the implementation of the SiLab chips "soft mute function" which enraged DXers because, rather than amplifying weak MW/SW signals actually does the opposite; making them "fall off the cliff" once signal strength goes below a cutoff.

The Ccrane SWP was a more traditional PLL/superhet design that was well conceived except for an occasional annoying design flaw: a digital up/down volume adjustment in lieu of a traditional knob; it powered up too loud, had steps that were too coarse to get the volume right, and you could not lower the volume enough to make for comfortable listening through headphones. The AR-1733 which is the immediate predecessor to this model, has serious performance issues on MW.

The designers of Skywave appear to have taken all of this in; perhaps that is why the release of the radio was delayed so many times. In using it side by side with older models, all the good points stand out. Sensitivity is remarkably good, especially on MW where strong AGC action and excellent useable sensitivity gives great volume even from daytime fringe stations - comparable to larger sets like the PL-660 for instance. Volume control is once again handled using a traditional analog knob. All 5 of the SiLabs "virtual filter" bandwidth settings are implemented (6 - 4 - 3 - 2 -1 KHz) and work very well. The odd tones and artifacts of previous DSP designs are mostly gone. I cannot detect any evidence of "soft-mute" being activated. In fact, the overall "feel" and sound of the Skywave reminds one of all the best points of PLL/superhet sets of a few years back (e.g. Tecsun PL-200/Eton E100, etc). Also for me, where many radios suffer bleed-through of strong MW signals all over the place, the front-end selectivity of this radio is admirably good.

Compared to Tecsun DSP sets some differences stand out. There is no digital signal strength display, only a bar graph. The sound from the speaker is rather tinny (even with the "hidden" audio tone control set to "music"). There is no direct control over the dial light. A nice feature that the AR-1733 had (ability to lock the tuning wheel - only) is not carried over. Also many have criticized the lack of SSB capability; not an issue of size really (ages ago, the even smaller Sony ICF-SW100 implemented SSB as well as synchronous AM) but perhaps cost and the capabilities of the available DSP chips.

Michael,
Battery gunge can often cause short circuits, so a magnifying glass and a very strong light is a good idea. Your worst enemy though is going to be corrosion, as you might have already guessed. This might also mean removing the circuit board from the other part of the case to look on the other side of the board. I don't know that model, but you could look online for a service manual, trying some of its other identities. Perhaps Paul or Gary might be able to help as they are familiar with this radio.

The spring terminals are often stainless steel or plated. They'll usually just wipe clean. The others may be copper or brass. They might need a bit of help with an abrasive material. An emery board donated by my wife has stood me in good stead. They have separate grades on each side which is handy and fits into places my 10" rasp won't.
Good Luck!

Thanks, Tom, I have done most of that, but will try it again - with a magnifying glass :-)

I fear the original battery leak may have fed alien voltages to parts of the signal processing circuitry. But maybe it can still be saved. Any additional ideas will be most welcome.

Before opening the case, use cotton wool buds to wipe out excess gunge from the battery compartment. Stubborn bits can be helped by dipping a clean bud moistened, not dripping with white vinegar or lemon juice. Be careful that no liquid spills out of the battery compartment and inside the receiver. Clean around the battery terminals too. If the negative terminal(s) are springs, clean them too the same way. If you can reach the other terminal clean that too. Sometimes you need to remove the case to get better access to that.

Once inside go through the same cleaning process, carefully and a bit at a time. Loose solid pieces can be picked up with forceps, but don't squeeze too tight. Just keep going until all the green has gone. I sometimes finish with a quick wipe around with a bud moistened in isopropyl alcohol. Cotton buds with longer stems are often sold by electronics shops and suppliers. From the good old days of cleaning oxide off tape heads!
