Re: Topband: 470 non carbon resistor

[Tim Duffy]

Hi Rag

Here is a good source for the correct 470 ohm resistor.

Hi Rag,

the important is to look for carbon composition / ceramic composition
resistors
at 2W power rating at least. The Ohmite has their OY series / 2W for
example.

Mouser:
588-OY-470-E 
http://eu.mouser.com/Search/ProductDetail.aspx?qs=K%2fk%252b2unYRtW4en7Bt3IF

Farnell / Newark:

The resistors datasheet:

Re: Topband: Topband Digest, Vol 165, Issue 9

[Peter Bacon]

For those questioning what this is about.  In ON4UN's book (I have the 5th
edition and it is 2.4.3) John describes the Midway Midnight Peak as
"North-south (+-30 deg) paths exhibit a clear propagation peak at local
midnight time halfway on the path, both on 80 and 160m."  I agree it would
be nice if there is a piece of software to calculate this.

Topband: midnight peaks

[K1FZ-Bruce]

Larger numbers of low-banders came up at  NA ~midnight from both sides of the 
Atlantic. 
 
More fun for all.

  I often get a peak from 11:30 to 12:30 from Europe
 
 Work F8IQS, G4ERZ, G3ROO, SV3RF, LY2OU, LA7THA, G4UFK,  and others
 
Even though its near midnight here, it is aproaching sunrise  there
