My Maritime ATU

This afternoon my SEA maritime ATU was down for routine maintenance inspection.  I used the opportunity to replace the RG58 coax patch inside the tuner with an RG213 coaxial cable.  Unfortunately my inventory of antenna plugs reveled no N-connectors so I decided to keep the PL-259´s for now.  The SEA 1612C is a versatile, fully automatic microprocessor-based antenna tuner. Upon the first receiver impulse, the transceiver initiates a rapid microprocessor controlled search/match procedure that determines antenna characteristics and inter-connects the proper elements for optimum match and power transfer.  The SEA 1612C is housed in a weatherproof molded case designed to withstand rugged environmental conditions encountered aboard ship while mounted on the external weather decks thus an ideal solution for the Icelandic harsh weather conditions.  The tuner is connected to a 43 feet horizontal antenna with the ground connected to a metal roof acting as an ideal counterpoise and will without any effort tune the 43 feet wire to any frequency ranging from 160M to 10M.  RF power handling capability is 150 Watts PEP. 



ACOM in the Shack

This week the long awaited ACOM 1000 arrived.  I purchased this HF linear after an in-depth analysis and reviews by pleased customers worldwide and the rock solid reputation ACOM in Bulgaria has achieved for their products and excellent customer service.  Looking forward to the ride.

Bird Dummy Load

Pending the arrival of  Mr.  ACOM,  this new old stock Bird Dummy Load came across my path.  It´s a MILSPEC unit withstanding close to one kilowatt.  It does´t hurt it´s in Navy haze gray colors, a reminder of days gone by.  Now doubt it will come to good use.

Programming the Spectra

As a loyal Motorola fan I recently acquired my second VHF Motorola Spectra mobile transceiver.  The radio is in mint condition considering it´s age and without any capacitor leaks or other pending issues.  The first step was to program the radio with selected frequencies.  This required a 25yo Motorola RSS software running under DOS, a RIB box with serial cables and a PC capable of communicating with the radio.  Since I already own a vintage 386 AST Acentia laptop with Windows 98, I decided to use that route instead of using a DOSbox or any other means of virtual based programs.  The frequency programming, entering CTCSS and DSC codes turned out to be a straight forward process but the entering of zones and scanning functions required a more in-depth understanding of the RSS software functions. The price I paid for this MILSPEC Motorola radio is only a small fraction compared to the price of a modern day 2M Ham Radio transceiver.
