 This portable receiver had, among others, the Grundig Satellit receivers, the [[Zenith]] Transoceanic, the [[Panasonic]] [[RF-2200]] and the [[Sony]] Earth Orbiter [[CRF-5080|CRF-5080 / 6090]] as competitors. Due to its circuit design, the Barlow Wadley XCR-30 was a good performer even in [[ECSS]] mode (reception of weak AM stations in single sideband mode with the BFO replacing the original carrier) and had a dial accuracy of 5 kHz on the linear analogue dial. This portable receiver had, among others, the Grundig Satellit receivers, the [[Zenith]] Transoceanic, the [[Panasonic]] [[RF-2200]] and the [[Sony]] Earth Orbiter [[CRF-5080|CRF-5080 / 6090]] as competitors.

 The receiver is 295 x 185 (235 with carrying handle) x 100 mm wide and has a weight of 4.3 kg; it has a sturdy metal cabinet to avoid interference in the 45 - 75 MHz range due to the mixing process. There is a carrying handle on the top face and a shortwave broadcast band table can be folded out underneath. The back of the unit can be unscrewed to access the battery compartment with space for six [[UM1]] mono cells. The receiver is 295 x 185 (235 with carrying handle) x 100 mm wide and has a weight of 4.3 kg; it has a sturdy metal cabinet to avoid interference in the 45 - 75 MHz range due to the mixing process.

 Apparently, the manufacturing and final inspection at Barlow was subject to daily fluctuations, the first transistor was susceptible to electrostatic discharge and the single circuit board to cold solder joints and hairline cracks, so that a second-hand unit should be tested before purchase. Apparently, the manufacturing and final inspection at Barlow was subject to daily fluctuations, the first transistor was susceptible to electrostatic discharge and the single circuit board to cold solder joints and hairline cracks, so that a second-hand unit should be tested before purchase.

 My XCR-30 was never meant to replace the Sony [[ICF-2001D]] as my favourite travel set, but it deserves a place of honour on my desk as an oldie thanks to its fascinating circuitry, unobtrusive exterior and always amazing reception performance. My XCR-30 was never meant to replace the Sony [[ICF-2001D]] as my favourite travel set, but it deserves a place of honour on my desk as an oldie thanks to its fascinating circuitry, unobtrusive exterior and always amazing reception performance.
