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.

DX’pedition: first test of deployable 200 metre longwire antenna by Oxford Shortwave Log

A view looking toward  Oxford Shortwave Log DX’pedition territory; a wood in rural Oxfordshire

Regular viewers of my youtube channel will know that I spend much of my shortwave listening time out in an Oxfordshire wood where QRM is negligable and Tropical Band stations can be heard with, at times, unprecidented signal-to-noise. Regular viewers will also be aware that I enjoy experimenting with different antenna set-ups, particularly pushing the boundaries with longwires coupled to portables. Having applied my rather modest practical skills, I constructed a 200 metre deployable 200 metre longwire antenna and finally got around to testing it, with my Elad FDM DUO and Sony ICF-2001D. There are a number of reception videos still to be uploaded to the Oxford Shortwave Log youtube channel, howvever, the immediate information and entertainment of SWLing Post readers, I have included two here. 🙂

The first is the more commonly heard Emisoras Pio XII from Boliva on 5952.5 kHz using the Sony and the second, the much more rarely reported Radio Chaski from Peru on 5979.9 kHz using the Elad. Both reception videos were very encouraging. In fact, I would go so far as to say they demonstrated excellent reception witihin the framework of their respective contexts. Emisoras Pio XII was almost booming with unprecidented signal strength and clarity, whilst Radio Chaski was heard with discernible audio. Neither station had been received as well at my QTH or the woods, previously.

I hope this gives other DXers ‘food for thought’ with regard to experimenting with antennas and perhaps more importantly, making significant improvements to SNR by removing themselves from the ubiquitous blanket of QRM generated by all of those devices at home that are intrinsic to modern life. Thanks for watching. 73.

Medium Wave DX: CBC Radio 1 Gander, 1400 kHz, remarkably clear signal in Oxford UK

CBC Radio 1, Gander, heard in Oxford UK

A really great signal from CBC Radio 1 Gander – the best I’ve ever heard on this or any other medium wave frequency, complete with a clear station ID and very much out of season so-to-speak. I can’t remember recording any Medium Wave transatlantic signal with an audio bandwidth filter of 7 kHz, which says everything about the relative strength of this signal; 2.5 to perhaps 4 kHz would be more typical. As the subscribers to my youtube channel Oxford Shortwave log will know, I dabble in Medium Wave DXing, however, it requires a lot of patience because conditions of good propagation can occur quite infrequently. This is where the band recording features incorporated into the Elad FDM-SW2 software (and similar software for other SDR receivers) come into their own, allowing you to record the entire medium wave band, for example, for later analysis. As for the Wellbrook ALA1530 active loop antenna, I can’t praise it highly enough, both in terms of combating QRM and overall performance as a function of compactness.

Recorded in Oxford UK using an Elad FDM DUO and Wellbrook ALA1530 active loop antenna (indoors) on 29/06/16 at 03:00 hrs UTC.

Elad FDM-S2 on sale $499 US

Elad-Summer-Sale

While browsing the Elad website, I noticed an End of Summer sale on their US retail page.

The sale includes one of my favorite sub-$1000 SDRs–the Elad FDM-S2–priced at $499 US (originally $580). If you’ve been on the fence about purchasing the FDM-S2, this might be a good time to bite the bullet. Certainly a great value, in my book. Click here to read my review.

Note that the Elad FDM-DUO stand-alone SDR transceiver and FDM-S1 receiver are also on sale.

I don’t see an indication of when the sale ends, but I assume it may last until the end of summer. If interested, you might contact the Elad sales department to confirm.
