The XDR-F1 is the best radio receiver thats known to me. It's much better than a Telefunken HT850 or similar radio's

Hallo Zvartoshu

I have the bigger Brother the XDRS3HD. Super reciever. Best crossmodulation suppression.(I live 2 km from 4 Fm trasmitters power variing 15 to 50 Kw. Selctivity mostly 100 kHz beside strong station i can DX.
Do I understand you put 220 V at de Powersupply of the XDR. It is comming from USA and needs 115 V.
Or do you have an AC adaptor from 220 to 115 volt???

i have original adaptor , and ups send 220V , not know sistem voltage for radio , know real dx in south romania , exemple trt signal 90.0 or 94.5 for demirkoy tepesi at 300km distance .
Not understand this received , but my receiver in this zone with test , last year test , detect many stations via troposcatter , exemple 88.8 FELEACU romania RRACTUAL , 93.1 TGRT ISTANBUL .. 101.1 RRACTUAL IASI PIETRARIE , distance 300 - 448km continous troposcatters .
My radio is know with an amplifier in pcb with bf999 . Not know sony xdr , and question about this radio .
Is an enigme but this radio speech all dxers , and my friend add in romania this radio . Not understand what problem have , this radio have Input antena with problems , IC shematic with many LC filter , but signal is very low . Dx is at low level .
In other exemples , 2 bulgarian dxers have this radio .
First detect dx , signals , exemple , serbian , hungarian , croatian .
Second , detect , low signals with all stations .
For me , this radios have a problem . Sure dx-ers when chage 2 xdrf1hd detect this bug .

Is your power convertor maybe broken? The Sony needs 110 Volts.

convertor functional 110V to 220V , i send mail to my firiend and my friend speech about a 110- to - 220v adaptre ac

It could be your Sony is broken. Normally i think the Sony XDR S3HD and F1 are the best existing tuner aviable at this time.

The high-selectivity and sensitivy is a side effect off the IBOC HD capability ;)

Not good for me , not good for my friend dx-er , this is a radio normaly and selective .
My radio blaupunkt is a real radio good , but add continous scatters at minim 200km distance and maxim 450km . I detect scatters in moment with best rain or fortune .
