From USNERDOC : 3 part series – Get Your Comms Up

He takes you step by step through what and how to set up a go bag SWL kit – really good step by step on how to put together a portable long wire – completely simple explanation without being condescending – pretty decent series – and if you get a chance check out his YouTube site – a lot of stuff there as well . . .

Noise Cancellation Part #2

MIKROWAVE1 dives headfirst into the rabbit hole with this video . . .

Probably the simplest solution – but NOT A CHEAP DATE! – is from DXEngineering – almost plug in solutions for you – 2 different models from them – the Noise Canceling Signal Enhancers MFJ-1025 @ $269.95 and the Noise Canceling Signal Enhancers MFJ-1026 @ $299.95 – the $30 dollar difference being an antenna on the unit itself – which helps you detect/cancel noise from your in-house environment. And believe you me – there is a tremendous amount of noise coming from in your house – LED light bulbs are very noisy – fan motors – such as the blower motor on your furnace or your a/c unit outside – or window unit – computers/monitors – TV’s – Everything that consumes electricity makes an electrical “splash” of some sort or the other.

One of the favorite things to do was night fishing – before the “crew” got all caught up in life – Yeah, I know – life ain’t bad, but this day to day shit will kill you – was to drag out the GE Super Radio with a set of fresh batteries in it while fishing and listen to the oldies show on AM radio out of Toronto, Canada just as clear as it it was a local station – on from 9pm to midnight – and no I don’t remember the call letters – but I remember damn near every catfish! . . .

One of the primary reasons it was so good – besides the radio? – you are out ( electrically speaking ) in the middle of nowhere – no interference! I worked some incredible AM broadcast band DX over the years while camping – and the vast majority of it was done with transistor pocket radios – nothing special or fancy . . .

A Look at 2 AM Broadcast Band Filters

These pics were done running Airspy SDR# Studio v1.0.0.1910 – the sdr is an Airspy HF+ Discovery – the settings : HF AGC / off – HF preamp on – HF att 0db – the pics were taken as fast as I could put the filter (s) in line and switch them – so the conditions are basically the same for all – Frequency is set 1.110.000 – 1110 KFAB – 50 kw flamethrower – 60 ft long wire . . .

no filter . . .

RTL-SDR 2.6 Mhz HPF “Broadcast AM Reject Filter” . . .

NooElec “Flamingo” AM Broadcast Band Notch Filter . . .

They both work to quiet down the AM broadcast band – to explain the differences I am going to link to 2 sites to get you some idea of what is happening – #1HERE and #2HERE – it’s difficult to explain something when you don’t understand all you don’t know about it – LOL!

Once I get the new room set up I will do some thorough testing of both – as well as testing of the variety of settings on the software – Airspy SDR# Studio v1.0.0.1910 – as you can see there are a whole bunch of settings . . .

I will keep fiddling with this and try to get a clue as to what I’m doing – I’m probably 75 days out from getting the new room/studio set up – yes it looks like the studio may become a reality – I’m being drug – kicking and screaming – into the 21st century – so real pictures are coming and a YouTube channel may be up and running by the first of the year . . .

I’m not holding my breath on the YouTube thing and I don’t recommend that any of you folks do either . . .
