I'd be curious as to how a R390A compares to the Drake R8, which is one of the more recent MW DX tabletop receivers that seems to get the biggest reviews.

I remember a few of the top MW DXers in the 70's and early 80's used R390's, along with Drake SPR4's.

I currently have a Drake R-8B and I can say it is a very good receiver.  I used to have a R-390A and to this day consider selling the R-390A my biggest mistake in amateur radio in my 40+ years in the hobby.

Do I like the easy turning tuning of the Drake-Yes.  Do I like the direct digital input-Yes.  would I rather sit and tune the R390A all day vs the R-8B-No.

So, which radio would I have if I could do over knowing what I know now?  R-390a is the easy winner for me.  Your mileage may vary ...

RENTON481 .. Thanks for the correction.  I was under the wrong impression about the internal Superradio antenna ao thanks for correcting me.  I never opened the radio up to peek inside but I am going to do so.

No problem... wasn't trying to be snarky -- I have three Superadios so I'm sort of into them as MWDX radios...

I don't know which Superadio you have (1, 2, or 3) but when opening up the GE Superadio, always have the power button turned to 'on' (on all three models).. Otherwise it can break.  If you break the power button by accident (can happen even if you're careful), it's difficult to fix, but I put a toggle button in the back of one of my SR's after wrecking the power button.

If you have the Superadio 1 or Superadio 2, the front of the case will come off better if you have the tuner button shaft turned to where the flat side of the shaft faces down. The shaft will wiggle clear of the hole in the front of the radio easier if you have it turned flat side south...

Enjoy your Superadio. I got one used at a thrift store with paint splatters on it, too. My best Superadio.

Shows what you can pull in with a few choice beverages and 24 hours (more or less in DEC-Jan) of darkness.

If I remember, Kongsfjord is about as far north in Norway as you can get.

One of the small market 1000W AM radio stations here in Northern CO is KIIX 1410.  You drive through their coverage area in about 8 minutes.  I can't believe that it's in Bjarne's log!

I remember as a kid reading with fascination about a MW Dxpedition to Newfoundland.  I still have dreams about living in some cold remote perpetually dark seaside QTH like that, with beverages and K9AY's.

Sorry drifted off topic.

I don't understand how the Norwegians pull in those obscure low power broadcasters. Also thought it was odd that no Missouri stations were listed including clear channel 50-KW stations with huge antennas. Perhaps they had logged KMOX (for example) many times before and didn't bother to mention it.

Whoops, one Missouri station is on the list: KLFJ in Springfield running 5,000 watts day and 28 watts night.

Probably insignificant, but interesting to note, Kongsfjord is just a few degrees north of KIIX's 25 degree theoretical major lobe at nighttime directional, at about 4450 miles.

One Oklahoma AM station I was at would occasionally get a QSL card from Australia, usually coinciding with someone forgetting to switch from 1kw daytime non-directional to 250w nighttime pattern on time.

Yes - I expected to see the big 50K watt clear channel stations like KOA, KMOX, KFI etc. in the log, not stations like KIIX and KLFJ. (!!)

Beyond the Class A-D NRC info, how do you access the specific directional lobes and coverage/pattern/protection areas for stations like KIIX?

I have been very impressed with my SALA antenna. I can sit on an AM channel, electrically rotate the array (every 45 degrees) and pick up different stations. Same on the NDB band. This summer I'll add variable time delay so I can  alter the rear null arrival angle.

Interesting subject. A quick run through the MW broadcast band at 2:30PM local netted me 61 good copy stations with my Yaesu FTDX9000 and a Hustler 5BTV. Located in southern Ontario. Gonna have to give it a shot with my 160M inverted L.

Let's all try it. Tune briskly from 530 to 1720 kHz at 2:30 PM local time. I have no idea what my receivers can hear on such a test but I'll bet it's more than 18 stations. Signals must be somewhat understandable to count. I may also fire up an old Zenith 5-tuber. Yes, I know, listeners out west are probably screwed.

Current scores:
Collins R-390A, high 160m dipole,  SC:         71 Stations
Icom R-9000, high 160m dipole, SC:             18 stations
Yaesu FTDX9000,  5BTV vertical, Ont:          61 stations
