The RF Workbench / Re: Tecsun PL-880 external MW antenna idea
« on: July 03, 2020, 1835 UTC »
Kage;

Glad it worked for you.  Yeah, I had a bit more room on the rod in my 880.  On the other hand, the rod butted right up against the case corner and I had to shave some plastic to be able to slip wire onto the rod.

Prior to doing this mod on mine, I could only capture a couple of IL NDBs at night.  Afterwards, I was able to easily log most of the common CAN NDBs as well as a cupla dozen USA states.

Thanks!  Maybe I'll be able to hear it again this season assuming, of course, that somebody's Christmas gift doesn't come screaming out of the sky and nuke it.

There is a mod for the 880 which allows it to use an external antenna for LW.  It is located here in the NDB Group:

https://groups.io/g/ndblist/message/105858?p=,,,20,0,0,0::relevance,,pl-880+modification,20,2,0,70214479

I have performed this mod on my 880.  It took me about 45 minutes and was pretty easy.  This mod allows me to use my standard NDB antenna - an amplified 96" whip - with the 880.  While I wouldn't call this setup a DX Machine the sensitivity at LF is greatly enhanced.
 
I am not sure if you need to be a group member to access this file, but here is the short form procedure.  It's possible that this was also posted in another group - poss an ultralight group - but I have not been able to fine it. 

1) Open the 880 back. 
2) Wind a few turns (I used 5) of fine insulated wire around the end of the ferrite bar at the end near the Antenna Jack.
3) Tack the wire in place with hot melt or other glue.
4) Solder one wire end to the PCB  pad near the antenna jack which is connected to the jack ground.
5) Solder the other wire end to the PCB pad which is connected to the jack tip; this is not used normally.
6) Button up the back.  Most any antenna can now be plugged into the jack with a mating plug wired to the tip and ground connections.

I did not need to add a LPF between the antenna and RX.  Of course, a winding could be temporarily placed on the ferrite bar and patched to the antenna prior to doing any soldering to estimate the appropriate number of turns required for your setup.

Credit for this mod goes to Steve Ratzlaff AA7U and Geir Laastad LA6LU.

Logs from Downers Grove, Illinois

I had been hoping for enough free time this spring to do a final review of recordings from last season based on notes I had jotted down in the log book.  I guess you have to be careful for what you ask for...

These are the final logs from the Winter season, and represent a deep dive into files.  In retrospect, it was a truly amazing season.  I was able to learn a couple of lessons, and I had a couple of assumptions on my part torn to shreds.

First, capture of European and African TAs is possible in the USA midsection.  TAs were noted in the first week of December, January, and February.  While the vast majority of these could only be regarded as tentative logs, a handful were solidly IDed, and could be considered as solid logs.  An apparent monthly periodicity is definitely something to keep in mind next season.

Secondly, I had been reading the logs of listeners on the west coast and in the southwest who routinely log NDBs from the Pacific and I had assumed that reception here in the central USA was not possible.  Not true.  It took a ton of searching and digging but I was able over time to obtain definite logs for about 17 of these.  Again, the DX juices are already flowing and their are still a large number of targets in the crosshairs for next season.
