HDSDR vs. SDR console and a nice Radio Santa Fe 1070 log

This year I switched from HDSDR to SDR console. I have to admit that I wasn’t immediately a big fan of it as SDR console is definitely a bit more complex interface. But HDSDR didn’t support my Elad FDM S3 which forced me to adapt.

A few months down the road I don’t want anything else than SDR Console for my medium-wave DX activities. The three biggest advantages of SDR Console over HDSDR are:

  1. SDR console allows you to adjust lower and upper bandwidth indepently. This allows you to optimize the amount of modulation needed to get an audible ID.
  2. SDR console offers a variety of highly tuneable filters. I particularly like the NR4 filter which might distort music a bit, but is a great help to improve voice.
  3. The navigator functionality is so helpful to search your overnight recording for signals. I use 2 minute slots, and when a proper carrier is detect move forward (or backward) in 10 second steps.

Are there some disadvantages? Yes there are. There are more options, more functionality, but that also adds a bit of complexity. Scheduling a recording with HDSDR is a bit easier when you want to set both your center and tuning frequency: for example when you want to run an overnight DSC watch on 2187.5 while recording the entire medium-wave band. Starting an audio recording is a bit easier in HDSDR as well. But all in all, SDR console did help me to improve my medium-wave DX.

As an example, attached is a recording of Radio Santa Fé, Bogotá. I heard this station while staying on Curacao last year and even got a QSL. But I never expected to be able to pick up their ID in my noisy suburb location: “Eschucha Radio Santa Fe, 10-70..”. And of course I sent a report and applied for a confirmation.

Recording of Radio Santa Fe, Bogotá on 1070 kHz.

QSL La Voz de Bogotá 930 kHz

An email to QSL La Voz de Bogotá on 930 kHz. Another Colombian station I received during my stay at Curacao. I struggled to find an email address, but Arild was so kind to help me out. V/s is Mr. John Rodrigues

Confirmation email for La Voz de Bogotá on 930 kHz

La Voz de Bogotá started in 1931 as one of the first radio stations in Colombia. Today it is the flagship station of the Todelar Network. They also operate a number of FM stations like La X, of which you can see the logo on the confirmation mail.

QSL Radio Santa Fe 1070 AM

I heard Radio Santa Fe during my stay on Curacao, and Ms. Blanca Bernal was so kind to QSL Radio Santa Fe 1070 AM.

Radio Santa Fe was founded in 1938 by Hernando Bernal Andrade and his wife Luisa Mahe. Bernal purchased a communications system from a crashed airplane, repaired it and with his wife bought a house in Centenario, a neighbourhood in southern Bogotá, where the first broadcasts of Radio Santa Fe started.

I wouldn’t be suprised if Ms. Bernal is family of the founder. And while I am very grateful for the response of Ms. Bernal I regret that they don’t do something like an e QSL….Years ago they sent a QSL like this:

QSL BBN Radio Bogotá 1100 kHz

A QSL for my reception of BBN Radio from Bogotá, Colombia on 1100 kHz. BBN stands for Bible Broadcasting Network. I have to admit that, unlike TWR and AWR, I was not familiar with this station. That is most likely because they do not operate on Shortwave. The organisation runs quite a few FM stations in the United States, in addition to 4 low power AM stations. But they are also active in 14 countries in South America, with medium wave presence in Chile, Colombia, Panama and Venezuela.

Red De Radiodifusión Biblica (BBN) from Colombia
email to QSL Red De Radiodifusión Biblica (BBN) from Colombia

During my stay in Curaçao I received the station “Red de Radiodifusión Bíblica” from Bogotá, Colombia. I heard a program with a Bible Class and a lecture from the apostle Matthew. I sent my report to red@bbnradio.org .
