Arlan manufactures the 'Radiosport' line of phones and headsets in the USA. Experiencing the weaknesses of other products during his motorsport career in the 1990s, the founder of Arlan started to develop and manufacture his own line of headsets and phones for the professional customer. The products are characterized by an excellent robustness, good wearing comfort and a modular design.

The Arlan Radiosport RS-20S is a headphone for radio communications, for example for aviation, motorsport, short wave listening or the amateur radio hobby. The headphone is solidly constructed, for example the outer shells of the speakers are made from carbon fibre reinforced material. The headset frame is made from light spring steel which assures a good fit without too much pressure. By using thick, gel-filled ear pads the headphones sit very comfortably over your ears, while also offering a strong reduction of ambient noise by 24dB! This allows you to listen to a faint telegraphy QSOs even in the thick of a contest. The ear pads are additionally equipped with removeable, washable cotton covers.

The speakers have an impedance of 32 Ω, making it a good match volume-wise for standard radio speakers and desktop speakers. You Will not need to adjust the volume much when switching between speaker and headphones. Included in the shipment is a detachable cable with 3.5mm stereo phone plug, an adaptor to 6.3mm phone plug is also supplied. The RS-20S headphones weigh c. 480g.

The RS-60CF is the top model in the line of Radiosport headsets made by Arlan. The manufacturer started to develop these headsets for his own use when he was an active motorsports driver. The goal was to have better intelligibility and higher comfort of wearing the headset for long hours. Further a much better durability was to be achieved. The result is a top-quality headset with a boom microphone for radio communications. Since the establishment of the company more than 250'000 items of this product line have been sold.

The robustness of the RS-60CF is a result of the use of good materials and good workmanship. The speaker shells are make of carbon-fiber reinforced plastcs, the holder and frame is made from lightweight, stainless spring steel. Due to the extra-thick ear pads - which are gel-filled - the headsets has a great wear comfort. This allows you to use this headset for many hours during a contest without fatigue. Additionally the earpads are covered with a removeable, washable cotton fabric.

IN contrast to other headsets the Arlan products are built with modularity in mind. You can exchange the microphone even many years later. Together with the detachable cable a change of system from one radio brand to another is easily possible. Various microphones are available, for example dynamic and electret microphones with different frequency responses. This enables to radiosposrt headsets to be used with nearly all radio models without problems. The microphon capsules are mounted to a flexible boom. The boom can be rotated over a wide range, even fully upwards when not in use.

The following microphones are available:

• RS-M207 dynamic capsule with narrow frequency response, ideal for DX and the contest
• RS-M208 dynamic capsule with standard frequency response für daily QSO use. Occasional use in a contest or DX situation can be optimised with the equalizer of the radio.
• RS-M350-ADJ Electret capsule with narrow frequency resposne and adjustable signal level
• RS-M360 Electret capsule with standard frequency response for daily QSO use. Occasional use in a contest or DX situation can be optimised with the equalizer of the radio.

Furtjher advice for the microphone selection see below.

The headset has an easy to reach PTT pushbutton integrated on one side. This allows to continue the chat even when moving away from the radio desk for a moment, or when the headset is temporarily used on another radio without moving the PTT. To avoid a dangling PTT branch cable on the headset cable Arlan proposes to use the (often unused) accessory PTT input found on most radios. For this purpose a selection of adaptor cables and a footswitch is offered. And even when using a multimode controller like the microHAM MicroKeyer-II oder MicroKeyer-2R/2R+ you can attach the Radiosport headset directly with a suitable, ready made cable.

The connecting cable from the headset to the radio is always detachable and must be ordered separately. On the headset side professional Micro-XLR connectors are used. Various headset cables are available, which allow a direct connection to the radio without further adaptors. The headphones and connectors are wired for stereo, because many newer radios do offer stereo audio as well. For example one VFO on one side, the second VFO on the other ear. This is helpful for chasing DX when the rare DX station is constantly monitored on one ear, and the pile-up crowd on the other. For older radios a 'Mono' switch is provided.

A further speciality of the Arlan headsets is the secondary headphone connector. THis connector (3.5mm phone) is integrated on the right side of the headset and allows connection to a second set of earphones, for example for the second op during a contest. Or the copilot... The RS-60CF headset weighs c. 550 g.

Each headset RS-60CF requires a separate connection cable, suitable for the radio. On the headphone side, the cable is equipped with a professional micro XLR connector. On the radio side the appropiate connectors for phones and microphone are used. Integrated into the cable is a selector switch Stereo/Mono. PTT keying is done by the PTT button on the side of the headset, by Vox or by a separate PTT key via the accessory PTT connection, see below. The connecting cable does not provide a PTT connection.

The microphones for the Radiosport RS-60CF headset by Arlan can be changed at any time without problems. Various microphone types are available for different radio types and usage scenarios. In conjunction with the detachable connecting cables the result is a modular systems, which can be continously used even when changing the radio brand.

The micrphone capsules marked as "DX" have a reduced frequency responses. This helps better intelligibility in noisy channels, the signal becomes crisper and stands out from the crowd of the other signals. On the other hand the DX modulation would be too harsh for a prolonged chat at good conditions. For standard QSO use and chats, either on shortwave or on VHF the standard microphones are recommended. This microphone offers a wider frequency response, the modulation characteristics can be adjusted by the equalizer of the radio.

Each radiosport headset is equipped with a convenient and easy to reach PTT push button on the left side of the headset. In addition to this facility the manufacturer proposes to use either Vox on the (often unsused) accessory conenctor on the rear side of the radio. This avoids a dangling cable adaptor on the headset connection. Arlan offers various adaptors for PTT keying. If the accessory socket is already occupied by another application the PTT should be connected in parallel.

• Adaptor DIN-13I for Icom radios with 13-pin ACC1 socket, PTT to 2x Cinch sockets, HSEND and VSEND separatly. Suitable for foot switch RS-PTT-FS or other PTT keys with RCA (Cinch) connector.
• Adaptor DIN-7 for Icom radios with 7-pin ACC1 socket, PTT to Cinch socket. Suitable for foot switch RS-PTT-FS or other PTT keys with RCA (Cinch) connector.
• Adaptor DIN-13K for Kenwood radios with 13-pin ACC1 socket, PTT to Cinch sockets. Suitable for foot switch RS-PTT-FS or other PTT keys with RCA (Cinch) connector.
• Many other desktop transceiver require no adaptor, because these radios do have a standard PTT cinch socket, where the PTT footswitch can be connected directly.

The quality of a manufacturer is also visible on the ready availability of spare parts. Arlan offers suitable products for the wind shield and the protective ear covers of the headphones and headsets.
