My 2 cents... Do you have a real strong MW radiostation near you?

just completed my ubitx v5 built into a ready made case,
everything went together as expected, on switch on, nothing from
speaker but headphones ok. found a short across the speaker
terminals on the front panel circuit board (my fault!).
receive sounds very noisy, when a long wire is connected (not a
proper antenna yet....) I get a massive increase in noise, very
hard to distinguish stations even with volume control turned down.
Also find it difficult to tune into a ssb contact.
I have an old home made tx/rx (about 40 years old) that picks up
signals much better with almost no noise on same piece of wire
than ubitx and tunes into ssb signal very easily on its analogue
vfo, compared to ubitx.
is this normal for ubitx or do I have a problem?
Ubitx is supposed to have a sensitive receiver but due to the high
noise level does not seem as sensitive as my old rig who's arial
input goes straight into a diode ring mixer.
anyone have any ideas please?
