South American shortwave catches, rarely heard in Europe

RCRI

r9djHi there, I thought I would share some DX catches, all of which are rarely reported in Europe and yet I was fortunate enough to catch in Oxford UK, using a couple of different set-ups. The first is Radio Chaski Red Integridad from Urubamba Cusco, Peru, heard using an Elad FDM DUO and Wellbrook ALA1530 active loop antenna (indoors). The two subsequent receptions originate from Brazil; Radio 9 de Julho, Sao Paulo and Radio Transmundial,Santa-maria rtmCamobi, both of which were caught using the venerable Sony ICF-2001D portable receiver and my 200 metre longwire antenna. In all three cases, persistence was necessary whilst optimum conditions of propagation aligned with my listening schedule at home and my less frequent, but regular DX’peditions.

I am soon to deploy a 200 metre Beverage with adjustable termination resistance for nulling ‘rearward’ signals and matching transformers suitable for 75 and 50 Ohm receiver antenna inputs. I hope this will further improve my reception capability on both the MW and SW bands.  Another post specific to that project is in the pipeline, but in the meantime, thanks for reading/ watching and I wish you all very good DX.

Phil demonstrates the BHI NEIM1031 Noise Eliminating In-Line Module

Many thanks to SWLing Post contributor, Phil Brennan, who writes:

[Recently] one of your contributors mentioned that he purchased a BHI DSP unit at a discounted price. I purchased one (a different model to the one in the previous post) some months ago before I headed away travelling.

The post reminded me that I had made a small video demonstrating the DSP unit on my FRG7. The video shows me tuning the DSP on a broadcast of Voice of the People on 3912 khz. While QRM at my place isn’t too bad, it’s still present and the DSP does aid in clearing up a signal.

Voice of the People is usually jammed by the DPRK and the DSP also assists in reducing the roar of the jammer. Of course one can go to far with DSP and the audio can suffer from that underwater sound.

Thank you, Phil! The FRG-7 is an ideal receiver for something like the BHI module since it precedes on-board DSP. The great thing about an in-line module, of course, is that it can be used with a variety of receivers.

200 metre longwire: Radio Verdad 4054.9 kHz, Guatemala, unprecedented reception in Oxford, UK

verdadRadio Verdad, Chiquimula, Guatemala is quite a regular catch at home, however, their modulation is nearly always weak as the carrier struggles to lift above the ubiquitous blanket of local QRM. Another issue with hearing this station is the digital utility signal just above 4055 kHz, thus requiring LSB reception to reject the adjacent noise.

This particular recording of Radio Verdad was taken during a DX’pedition using the 200 metre longwire and is unprecedented in signal strength and clarity – in my personal experience. With fully discernible audio both the Elad FDM DUO and Sony ICF-2001D receivers perform very well with my experimental 200 metre antenna. I should point out that the audio from the Sony is significantly louder because the speaker on the Elad is puny, to say the least. However, the reception on the Elad sounds to me at least, superior to the Sony in terms of SNR, which is everything in Tropical Band DXing. As usual, I welcome your comments. Recorded in Oxford UK on 31/07/18 at 03:31 hrs UTC. Thanks for watching.

200m longwire update: rarely heard Radio Tawantinsuyo 6173.9 kHz, Peru, recorded in Oxford, UK

cusco

Hi there, I thought I would share my first reception of Radio Tawantinsuyo, from Cusco, Peru, recorded during the inaugural test of my 200 metre longwire antenna. Of course this  particular reception could be coincidence, but a very welcome catch in any case. Once again, the Sony ICF-2001D performs very well with this large antenna, but as on previous occasions, the rule is always to ‘choose your battles well’ targeting weak DX signals in uncrowded areas of the Tropical Band and elsewhere on shortwave. More details on the longwire antenna to follow in another post. Recorded at the ‘DX woods’ in Oxfordshire, UK on 31/07/16 at 00:27 hrs UTC. Thanks for watching.
