While the TX-1000 is still at the prototype stage, key questions remain about CE certification, final specifications, and the expected Tx-1000 release date—but the first glimpse confirms that this is shaping up to be a major new contender in the world of SDR transceivers.

Below, you’ll find the preliminary information shared by Lab599 as of today, April 24, 2025.

The post Lab599 TX-1000 Unveiled: Full HF, VHF & UHF SDR Transceiver Announced appeared first on PileupDX.com.

3B7A had five HF stations running pileups simultaneously. Each station was built around the SunSDR2 PRO HF, 6m and 2m direct sampling SDR transceiver with E-Coder hardware controller, an SPE 1.3K-FA amplifier, and a ModMic microphone. PerfoBox band pass filters from Low Band Systems where used to keep signal interference at minimum between the five stations. All stations where set up to be able to operate CW, SSB or RTTY.

On high bands VDA, the very efficient Vertical Dipole Arrays developed by Vincent F4BKV was used, and on low bands vertical arrays.

In the words of 3B7A team member Diégo F4HAU, below is the feedback using SunSDR2 PRO at Saint Brandon;

– “The SunSDR2 PRO works marvelously well, what a powerful product in a small box. The settings configuration settings done prior to the expedition works well. All team members where comfortable using the new SDR technology. The hardware controller, E-Coder, is very flexible and had been configured to provide access to the main functions needed”.

– “Visualisation of the pile-up via the spectrum displayed on the laptop is impressive and extremely useful to manage the pileup. Operating the SunSDR2 PRO felt great and allowed us to do our absolutely best to full-fill the need of the amateur radio community”

– “Furthermore the SunSDR2 PRO is perfect match with the lightweight Expert SPE 1.3K-FA amplifier providing high power for all modes”.

–  “Sometimes, the rhythm dropped a little bit. This is because we were searching for weaker signals in the pileup. Honestly, we can tell you that many have been logged because we saw the signal peak on the spectral visualization of the SDR. Using a classic VFO their signals would not been detected so easily.”

The post 3B7A Experience of SunSDR2 PRO appeared first on PileupDX.com.

Using past experience from their successful FT4TA expedition to Tromelin island and FT4JA Juan de Nova island Expedition, the experienced team lead by F5UFX Seb build their St Brandon setup around the SunSDR2 PRO transceiver, the SPE 1.3K-FA amplifier and ModMic attachable boom microphone.

3B7A will have 5 x HF stations on air simultaneously. Each station will have a SunSDR2 PRO with E-Coder hardware controller, an amplifier, and a ModMic. Logging is done using WinTest in network configuration and all stations will be able to operate CW, SSB or RTTY.

All 5 stations will have will have identical configuration from the keyboard to the amplifier. This will keep the operator focused on the pile-up and improve redundancy in case of any equipment failure.

In order to maximize the antenna configuration of the location and more specifically the proximity of the ocean 3B7A will use their classic VDA, Vertical Dipole Arrays, that have proven to give excellent results on the beach on low bands vertical mono band antennas will be used together with RX antennas to separate weak signals from the static noise. To minimise interference between stations 3B7A are using Low Band Systems PerfoBox band pass filters.

3B7A uses their ModMics in a very clever way; a microphone is permanently connected to the radio at each operating position. When it is time for operator change the mic is simply detached from the headphones of the leaving operator and handed over to the next operator who easily attach it to a pre-fitted magnetic clasp on his headphones. Personal settings in SunSDR2 PRO then allows for customised microphone equalisation, processing level, noise gate and RF clipping to optimise for each operator’s individual voice characteristics.

Disclaimer: SunSDR.eu/Pileup supports 3B7A with equipment support and the operator/owners of SunSDR.eu/Pileup has personally also contributed financially to the 3B7A DXpedition. You can support 3B7A too, just visit their donation page at 3B7A Saint Brandon DXpedition.

We wish the team F5UFX, F5CWU, F4BKV, F4FET, F2DX, F5PTM, F4HAU and F8ATM GL and huge pileups!
