Midland Land Mobile Radio (LMR/Commercial) ProductsThe Midland commercial repeaters, mobiles and portables are showing up in the used market in increasing larger quantities. Repeater-builder.com is looking for information on the various models and would like to have someone supply an overiew of the products - i.e. just what is a Syntech, or an XTR, or a 70-045, or a 70-342, or a 70-7030, or a 70-565, or a 70-1340B? We have a model chart below, but it's short on overview information - what makes one particular model better over another (maybe a better front end)? We'd like to present some combination of:

How to read a model number - i.e. what the differences are between the various models
Frequency ranges and which ones are crystal or synthesized
What makes one particular model better over another (i.e. which ones are the turkeys)
What it takes to move them onto amateur radio frequencies
If they aren't crystal controlled, information on how to program them (i.e. hardware programmer, PC program or front panel programming) would be appreciated, as well as what PC software do you need (and how to get it)
Information on any 'gotcha's' (i.e. you can't get the PA transistors for a model XXX, or a model YYY needs DOS-based software to program where a model ZZZ uses Windows-based software) etc.

One rule of thumb: The Syntech I radios use EPROM Modules and a hardware programmer, while both the Syntech II and XTR radios program with a PC, like modern radios.

Installation and Setup Tips for the Midland 70-1488W-CD Windows Programming Software By Sean Smock KC1IJS
For the XTR and SynTech II Mobiles. Does not apply to the DOS software.

70-1308A Programmer - Here's the schematic of a Syntech II and XTR programmer courtesy of Brett Kitchens KF4SQB
Unfortunately the wiring of the MAX233 IC is incorrect. There is another 70-1308A programmer diagram on the web, based on the MAX232 IC, and it's just as incorrect.

Does anyone have any information on the Midland Programming Interface 70-1052A ?
It is used to program the 70-045 / 70-065 / 70-165 / 70-265 / 70-166 / 70-266 series portables.
Or of the 70-1080 Programmer ?

The Midland Base-Tech series (possibly the entire product line) is made in Japan by Hitachi. These are crystal-controlled stations. Jeff AL1Q donated this two-manual set for the 50 and 100 watt UHF base/repeater stations, which cover the UHF band in two splits. The manuals were scanned, cleaned up, and stitched together by Bob WA1MIK. The first part had color X-ray views; the second part was obviously a reprint and the X-ray views were already in gray-scale. Both parts were scanned in gray-scale.

Base-Tech UHF Service Manual part 1 6.5 MB PDF file
This contains the operating and installation information plus service information for the non-frequency dependent equipment which is common to the entire Base-Tech line, such as the control circuitry, power supply, and cabinet. 10/88 revision.

Base-Tech UHF Service Manual part 2 25.4 MB PDF file
This contains specifications, troubleshooting procedures, technical data, and drawings for the transmitter, receiver, and RF power amplifiers of the 71-4050 (50 watt UHF) and 71-4120 (120 watt UHF) stations. 7/94 revision.

The Midland / Icom relationship:

The Midland 70-154A and B handheld are clones of the Icom H16 (16 channel high band, front panel programmable) and are identical except for the color of the plastic and the name on the housing. The 70-254A and B are clones of the U16, the UHF version. The programming instructions for the H16 and U16 that are on the Icom page at this web site will work for the Midland clones.

The following information came from Chris Baldwin KF6AJM: Kia gds software download.

The Base Tech II and III series base stations and repeaters are OEM by Kyodo-West in Japan. The rumor mill says that when the recent tsunami hit Japan, the Kyodo-West factory was destroyed. Prior to the ICOM takeover, units were also manufactured with 'Securicor' branding, as well as a few other obscure brands, most likely for overseas service. ICOM now manufactures the Base Tech III stations as the FR-9010 (VHF 110W) and RF-9020 (UHF 110W) P25 stations.
The Base Tech II is an analog-only station, available in VHF-Low
