The correct male 24 pin Molex connector body and pin contacts are available from Mouser Electronics as P/N 538-03-06-2242 and 538-02-06-2103, respectively. The Icom OPC-599 adapter cable adapts a male 13-pin DIN plug to female 8-pin (ACC1) and 7-pin (ACC2) sockets. Note: In some cases, the transceiver's BAND voltage line must be enabled (typically by bridging two pads on the main board). This will facilitate making up a suitable cable to connect the The corresponding pinouts for the 13-pin DIN ACC plug used with the IC-706 series, IC-7000, IC-7100, IC-7410 and IC-9100 are also given in Table 2. ( Note: The ALC line is mandatory when using the 1 is a wiring diagram, and Table 2 gives the interconnections. IC-2KL, female if plugged into the IC-2KL control cable.) Fig. IC-2KL, for example, the connections are as follows: The ACC(2) plug is a male 7-pin DIN, and the accessory plug for the 2KL is a 24-pin Molex (male if plugged into the If you wish to make up your own OPC-118 to connect an IC-756Pro3 to an Icom used to offer the OPC-118 adapter cable (female 24-pin Molex to male ACC1 & ACC2), and the OPC-126 (male 24-pin Molex to female ACC1 & ACC2). Adapter cables are required to interconnect transceivers and accessories with different accessory sockets. Earlier Icom products fitted with the 24-pn Molex ACC socket also provide these interconnections. Icom transceivers and accessories fitted with DIN ACC(1) and ACC(2) sockets provide the band voltage, +8V reference voltage and ground return on ACC(2). This is true whether the transmit VFO is active (assigned to the tuning knob) or not. When operating split, the band selected on the transmit VFO determines the band voltage (and thus the band selection in the external equipment), even if the transmit and receive VFO's are on different band. Note:The band voltage follows the transmit band selection. Table 1 (above) gives the band voltage range for each band. The 50 MHz band is not officially supported. The 18 and 21 MHz bands are grouped together, as are the 24 and 28 MHz bands. IC-2KL and IC-4KL amplifiers, the IC-AT150, IC-AT100 and IC-AT500 autotuners and the EX-627 antenna selector. This voltage serves to bandswitch external accessories such as the Band Pass Filter, 60M, 1500W, Fan Cooled (PB-F1500DX-5MHZ)įor September, our Word of the Day column will be focusing on new products that have become available since the 2020 DX Engineering catalog came out.All Icom HF and HF/VHF transceivers (except for the IC-701) provide an analogue band-selection voltage in the range 0 ~ +8V.These two new units are now available from DX Engineering:

Installed in optimal conditions, operators can experience up to 80 dB of isolation between all connected transceivers, regardless of band. LBS filters are also compatible with other manufacturer’s multiplexers. Models with 1,500W and 2,000W power ratings are available with or without fan cooling. LBS produces band pass filters covering 160 through 6M with power ratings from 200W to 2,000W. DX Engineering is pleased to carry these four new units: These multiplexers feature an insertion loss of typically less than 0.2ĭB, 35 dB of rejection for each radio from off-band signals, and VSWR of less Variety of band coverages and power handling ratings, from 200W ICAS to 2,000W Offers diplexers, duplexers, triplexers, quadplexers, and pentaplexers in a This allows each radio to operate a different band simultaneously without the need to purchase extra antennas and coax. Thanks to the use of the multiplexer, Hams can save money by allowing multiple radios to be connected to a single multi-band antenna. They’re solidly built units that work in tandem to consistently eliminate RF interference issues. LBS filters and multiplexers deliver as advertised.

There are more than a few good reasons for that.

If you’ve leafed through the DX Engineering catalog, you’ve likely noticed that an entire page is devoted to Low Band Systems (LBS) HF Transmit Band Pass Filters and HF Multiplexers.
