My new DSP portable is on the way

Post by pe1etr » 30 Mar 2019 08:17

I'm going to have to do most of my summer FM DXing outdoors this year, so I decided to buy a new DSP portable, as my existing radios are not ideal for outdoor FMDX.

I already have :
Tecsun PL-606
Eton G8 Traveler II
Sony ICF-M780SL

So the new one needs to be a stellar FMDX performer to out perform the above.

My shortlist:
XHDATA D-808
Radiwow R-108
Eton Traveler III Executive
Tecsun PL-398MP (Tecsun PL-390 no longer available)

They are all in stock in the UK and despatched by Amazon UK.
The priority is FMDX but very good MW is also important.
SW and LW are not really a big priority as I have a Sony ICF-SW7600GR.

Which one would you choose and why?
The radio will arrive on Monday 1st April and I'll post an unboxng/testing video and explain my choice.

OK I'll play. I'd probably go for the Radiowow R-108. It looks like a re-badged XHDATA D-808 but looks cheaper. If so, then the FM reception should be very good. It looks like it has an AM bandwidth button which should be good for MW DX.

I'm tempted to get one myself for taking away with me on holiday.
Good DX.

Good value for the amount of features, RDS seems pretty fast and it does OIRT too. Only downer is at my home QTH with Sutton Coldfield on my doorstep it does go a bit deaf on FM. But elsewhere it performs well.

I think some of you might be shocked by this recent FM selectivity comparison made in Budapest.

Two modified PLL sets and three DSP sets are compared.

Guess which one came last out of the five?

If I had some 80kHz Murata filters and much better soldering skills, It would be better to modify my Roberts R 9914 (Sangean ATS-505), which has excellent FM sensitivity and is similar on FM to the ATS-909..

yes XH data kicks the butt of at least 2 other rxs! so i didn't make the absolute worst choice!

is the hungarian stuff as compressed as UK FM?

I have unmodified DEGEN DE1103 PLL version and (I feel like) Is too wide on FM band. It's decent radio for SW though. I didn't bother to modify it for FM use. Perhaps I will consider the modification in future. I also have Tecsun PL-680, which is a great little radio but lacking RDS. In fact, DEGEN doesn't have RDS either. If I would looking for portable radio for FM DX, I would certainly look for receiver with RDS capabilities.

It arrived this morning, and seems to work well. I'm on my way to the seafront to test it outdoors. Pretty flat cx today unfortunately.

In case you haven't worked it out I got the Tecsun PL-398MP. I was going to get the Radiwow R-108, but at the last minute I chickened out due to the MW issues.

All three of the other radios have well-reported issues/quirks/faults.

Well that is a surprise. I would have thought the XHdata was streets ahead.

Please tell us about the FMDX and MWDX you've received on your XHDATA.

Just returned from the seafront.
The PL-398MP lived up to my expectations and even exceeded them.
No issues with spurs or overload on FM from the Radio Wave txer on Blackpool Tower.

MW was very good away from the noise. LW also was good on 198 and 252.

I'm not a Band II dxer and I use a Perseus/Jag combination for MF.

However what I have received on my XHData is irrelevant. There are plenty of online testimonials (including on here) to the bang for the buck it represents. It even has lsb/usb which I don't think the Tecsun has.

But if you are happy with your Tecsun then jobsagudun.
