DX-398 verses the YB-400 PE on the LW Bands
When I had the YB-400 PE tuned to 183 kHz Germany the DX-398 did not receive it strong like the YB-400 PE did it, the DX-398 was not sensitive enough as the YB-400 PE to receive broadcast LW DX. I feel that the best thing to do is get that modification from Radio Labs
and get that thing boosted. The only way that the DX-398 can receive LW broadcast signal from 1000 miles away is a use of a loop antenna with preamp or a longwire antenna with RF ground using a tunable coupler. If I ever get new DX-398, 909 they will be all modified and improved by radio labs for the LW reception improvement. And thanks to Grundig I don't need an external antenna that much to receive LW broadcast DX. I feel that Sangean did not do a good RF engineering improvement or design on the LW bands the reception is very poor compared to the YB-400 PE its kind of half reception, the DX-390 is the same way too, I didn't know that I can easily receive LW stations that easily at night on the YB-400 than my counterpart can receive.
Radio Labs however good thing did remedy this problem with poor reception on LW. Sangean
was trying to keep extra DXers from listening to the LW broadcast bands while some with the
YB-400 or other radios with Longwave can receive stations from overseas. I will soon do a video about the DX-398 vs YB-400 when I get the time to do it show you that this is regular
unknown defect in the LW bands. LW is very important to us as shortwave is. LW is will be
more reliable when the solar activity is low to very low meaning that communications on SW
will be less useful cause of a non active ionosphere. See, the longwave band does not have
to rely on the so called atmosphere, just the Earth and D layer itself. I feel that we need to
get this specification changed to improve all old and new upcoming Sangean radios for great
LW and MW reception. I am not using my DX-398 for advanced LW DXing like I used to
cause I don't need to pull out the longwire antenna and loop just to listen to France and Germany on 162 kHz and 183 kHz.
I feel that Grundig did a great job on the LW RF section and I feel that all radios need to be
this way. Now I know that I can trust that brand for my shortwave radio needs.
