Allow me to introduce myself, my name is Phil Taylor and in the coming months I plan to create a number of blog postings in an attempt to chronicle my journey through the world of amateur radio. 

I received my Foundation callsign, M6ESV in October 2014 and then completed the Intermediate examination, receiving the callsign 2E0DSQ in December 2015. I then passed the Advanced exam and received the callsign M0VSE on 19th August 2016. I also received the SCC (Special Contest Callsign) G7T in May 2017 and I generally use this when operating HF contests.

I am also an active member of the Leicester Radio Society http://www.g3lrs.org.uk who meet every Monday night.

One of the recent innovations that SDR radios have provided is the ability to display cluster/skimmer spots within the SDR Panadaptor. This facility is further advanced by logging programs which are able to customize the colour of displayed spots depending on various criteria. This is especially useful in contests where the spot can be used to indicate worked/multiplier status.

Regular readers will be aware of my contant battle with noise, both natural (QRN) and man-made (QRM) and some of my past attempts to mititage them. These include the purchase of a Wellbrook loop and both a WiMo QRM Eliminator and an MFJ-1026.

Both the WiMo and MFJ are quite capable at "nulling-out" noise sources but as one of my primary interests is 80m contesting, they just take too long to setup for each signal which really rules them out unfortunately. I had also mounted the Wellbrook on a cheap "TV" rotator but found that the nulls didn't seem to be deep enough for me to effectively remove the most persistent of noise sources that I encounter in my heavilly developed QTH. 

Sometime ago I became aware of Chavdar LZ1AQ and his designs for an active loop antenna amplifier (AAA-1) but what specifically interested me was the combination of multiple AAA-1 amplifiers with a variable delay line (VDL-1) which allows you to effectively steer the "array" with simple controls.  So I decided to purchase a VDL-1 and 3 x AAA-1 and see if I could build a steerable array.

One of the real benefits of an SDR based transceiver is that you get a visual representation of a portion of the band, or with some SDR transceivers you can view an entire band or bands if you wish. This is also in some ways a disadvantage as if you are in an urban area, you can see the enormous amount of man-made interference that is plaguing the bands.
