I ran a three way test on the weekend, this might help a bit:

Thanks Jay, I have found that my TEAC PR130 seems to draw down the batteries a bit, even when turned off.

To be clear, digital radios do use a small amount of power to keep the clock running but this kind of drain should take a long time to show up so if you use the radio even once a month you shouldn't notice it.

Hello Jorge,
Are you sure you have the correct radio? Those prices are way too high. The Eton Elite Executive is NOT the same radio as the Eton Elite Traveller!

I did it Jay, but I didn't find a noticeable improvement. I must say that I have to test better both filters on FM, as there are better stations to be chosen and test.

Narrow/wide positions are useful on MW band as I check this feature regularly with NA TA channels.

Everything has become more complicated now, what I do not understand Emoji

Amazon UK has a price of 107 pounds and do not serve to the Continent!!!!
Amazon Spain offers the receiver for 135 €.
Amazon USA 100$ including shipping to Spain.
Amazon Canada 70$CAN and they do not ship to Spain. (Pity, best price!)

So, bought it in the US is the best option. Final price: 82€ against 135€ from Spain. Unbelievable!!!

I will orden then to the US!

I bought mine from Amazon UK in 2019 when it was on special offer for GBP 37.

Maybe Amazon ES might stock it?

Right Jay! Well, I browsed  the internal PR-D19 receiver but not a P18. Are their ferrites identical?

On the other hand, is there a good way to extra screen internal circuits by wrapping copper foil?

It may be a matter of how low the noise floor is in your area but when I compare the PR-D18 and PR-D19 I get slightly better AM reception on the PR-D19.

Well done Peter! This June I will order one to benefit of PI decoding pn FM. And why not, also for MW DXing when the seaspn arrives!

Re: Good source for 18650 batteries?

As Jay pointed, I don't remove batteries but havevin mind that I do not have dozens of radios to use. I have a couple of them, a Panasonic RF-2200 and a Grundig Yacht Boy 300, both with batteries always in place. I switch them on at least 15 minutes a month. Everything run smooth with no drainage at all and batteries are still wealthy after a year!!!

That's actually works nicely. I do that in my radios and also in my
old car that I drive only on special occasions. From my experience, it
actually prolongs battery life

My PL-880 started draining batteries while off recently. Before this began, the battery would stay charged for months if not used. Now there is 15mA constant discharge current. The worst part is that it doesn't stop when the voltage is below 3V, killing the cell. I had to throw away 2 cells before I realized what's wrong.
As for the source of 18650 cells, the best source for me is tested cells from discarded laptop batteries.

Re: FM DXing - Sangean PR-D18 vs CCRadio-2E - Simple Side-by-Side Test

Jorge Garzón
 

Hi Johnny, 
Both Sangean, PR-D18 and PR-D19 are excellent performers on FM and very good on MW (AM). The bigger one with two speakers offers a deep and rich sound that fill a room, but because of that is a battery eater, so better use an AC/DC adaptor. Battery life when connecting earphones is much longer then.

Both models have identical performance on both bands despite the size, and both are out of UL and Small Portable categories, strictly speaking. 

As 'Sangeans' their features come into the scene: Very good sensitivity and reliable selectivity. Surprisingly here sensitivity on FM is brilliant and beats easily the CC pocket, being even slightly better than the DT-800. Also selectivity is better than the Sangean average as they offer an useful narrow/wide filter position and 100/50 kHz steps. It is a pity that the whip reaches just 67 cm unfolded and undoubtely with a longer one (100/115 cm), signals would be even better. 

I tested Sangean PR-D19 on MW with excellent results and some of the videos I made can be found in my Yotube channel. I recorded one about its FM performance Vs a big TECSUN S-8800. That was one of the first clips I recorded and my poor skills as a cameraman are noticeable there but I wanted to test both receivers with a close FM txer and two more, a low-powered and one afar.

Have in mind that the TECSUN telescopic reaches 100 cm and PR-D19 reaches just 67 cm. The price of the bigger radio multiplies by three Sangean's. And even more important, I discovered here that even switching off a receiver, the unfolded whip interacts with the unit being tested, so telescopic antennas must be keep apart to avoid a coupling effect. 


¡ Buen DX!

Hi all,
 
Just picked up a Sangean PR-D18 purely for it's FM reception.
 
I have to admit that this little radio, while ever so slightly bigger that the true UL definition (very close though), has EXCELLENT FM reception!
 
I would say that in my recent (very non-professional) tests between the PR-D18 and the CCRadio-2E, the PR-D18 was very equal to the CCrane, with each radio sometimes hearing a few things that the other could not.  

The Sangean definitely was as good as the R-108.
 
Reminder:  This test was only performed on the FM band as this was my target!!!
 
Costs:
  • Sangean PR-D18 - $50-ish USD
  • CCRadio-2E - $160-ish USD
 
For what it's worth!
 
Johnny
