Re: ULDXIndex and MWDXerDB V22.03
Yes, that is the formula I use.
I did also look at using two numbers but this got a bit confusing so I just give each signal a single index score.

Re: All Continental US States - 2022
Hi Steve
Wow, I was totally unaware that such a list existed! Now that I have something to search for I may change my listening habits a bit 😊. Very many thanks for that

p.s. Are you in

Re: ULDXIndex and MWDXerDB V22.03
Paul,
Do you compute like this? Dividing before multiplying.
ULDXIndexValue = (DistanceKM / PowerW) * SignalLevel
Regarding signal level, I guess '5by5' could be guideline. If the signal is both

Re: All Continental US States - 2022
Hi Johnny
The list is only relevant for one particular location. Your local stations may block reception of distant States.
Outside the US it is a different problem all together – but still

Re: ULDXIndex and MWDXerDB V22.03
I don't use the signal meter, it is more a mix of signal level, audio quality and how "clean" the signal is.--

Re: All Continental US States - 2022
Johnny,
Here's an OLD post (January 29, 1992!) from a Google group about hearing 50 states on AM/MW. Note that many of these stations have since changed call-signs, but I believe most of them are

Re: ULDXIndex and MWDXerDB V22.03
Now I understand the importance of taking Station power into account and not just distance. tonight I heard I in 1630 Iowa City. Only 200 miles away but not heard before. 10,000 watts. My radio

Re: Selectivity, sensitivity, quality
That’s one of the beautiful things about regenerative tuned loops. They can have sharper selectivity than the radio and can be detuned to favor one sideband or the other. A very well made FSL will

Yes, here in Australia we have the ACMA database which gives the "straight line" distance between my location and the station Ihear, this is the distance I use.

Re: ULDXIndex and MWDXerDB V22.03
Hi Bill,
I rate all the signals out of 5 and then use the below to work out the index value.
1 = 1.1
2 = 1.4
3 = 1.9
4 = 2.4
5 = 3
ULDXIndexValue = DistanceKM / PowerW * SignalLevel

Well done.
I have been a bit slow with starting my DXing for 2022, my work on MWDXerDB has taken up most of my spare time.

Those are just callsigns of some stations to use as examples.

Re: Anybody get a new radio recently?
The PL380 does not come with a charger. If I bought an adapter when buying the radio, would it recharge its batteries as well as powering the radio?

Yea, whatever you do, don’t use the evil Google. I use this site to obtain ‘as the crow flies’ distances:
