This ISM (Industrial, Scientific and Medical) band (see ) has a secondary allocation to Amateur Radio Service and is also used by a lot (Google вЂ900 MHZ Radio ModemвЂ™ and checkout the 452,000 matches) of other uses like: Amateur Radio Television, Walkie-Talkies, Ricochet Internet modems, Motorola Canopy radios, XBee 900 MHz modems and most notably consumer 900 Mhz Cordless Phones.

Changing the Frequency Hop Sequence: The ARF53 radios use the 33 cm band (902 to 928 MHz) UHF radio band. If you think it would be worth pursuing, let your dealer know so they can rattle the product managerвЂ™s chain. I have heard no rumblings of support for repeater operation. Web Page: Manual: Is an Adeunis Repeater in Our Future? New firmware was recently released for the ARF53 radio which supports repeater operation: Since the repeater operation implements a mesh network it would be possible to deploy several linked repeaters which could enable extremely long distance communication hauls. The ARF53вЂ™s donвЂ™t satisfy this requirement when placed 6 feet off the ground (the best we can do with the delivered cables.) Documentation for the factory modem can be found with the following links: 3 Of course (at least in the Western United States) we would like to be able to breakdown a 1 mile square section dependably. The range of the ARF53 radios is under 1,400 feet in urban environments. Not in North America, the radios and frequencies are slightly different.) Considering the price of an alternative, I think that the factory radios are great solutions! The price is nearly $5,600! You can read about it here: restRadiosforPM3.htm. We (Igage) sell an excellent Pacific Crest radio alternative that provides long range and TrimTalk compatibility. This radio is a 50 channel, ВЅ watt, 900 MHz frequency hopping spread-spectrum UHF radio that runs on 4.5 volts. The physics of radio coverage preclude an ultimate solution: вЂњLicense free, internal batteries, long battery life, long range, Pacific Crest compatibility and $200 total cost.вЂќ Ashtech chose the Adeunis () ARF53 data modem. Heavy Radios with big heat sinks Proprietary modulation schema Small Size and Weight TrimTalk compatibility Runs on Internal Batteries External Batteries Required No Extra Batteries Long Battery Life Short Battery Life Short Range ( 6 miles) No doubt there was considerable thought in the selection of the radio for the ProMark 3 RTK application. The system is delivered from the factory with radios that connect to the back of the ProMark 3 receiver and are powered by the receiverвЂ™s internal batteries. The Ashtech ProMark3 RTK GPS receiver is a single frequency, dual constellation (GPS & SBAS ranging) RTK solution. I have referred to the company and product as Ashtech throughout this document.

Your ProMark 3 GPS may be branded Thales, Magellan Professional or (in the future) something different. Thales Navigation was later renamed вЂMagellan ProfessionalвЂ™ and in late 2009 was renamed Ashtech LLC, while products continue to be flagged as вЂMagellan ProfessionalвЂ™. In any case, I (Mark Silver) am not responsible for any trouble that you cause! Background: The ProMark3 GPS receiver was initially released by Thales Navigation. If you make these modifications, you should insure that the modified radios are not used near power lines! In simple terms: There is a clear risk of electrocution and death from radios placed on tall poles.ДЄny electronic technician should be able to successfully follow the instructions in this paper. If you donвЂ™t have any common you should not consider making the described modifications.

If you use a pole longer than 12 feet, you risk electrocution and death from overhead power lines. If you do this, your ProMark3 GPS receiver will be toast. It is possible to mis-wire your radio cable so 12 volts is fed back into your ProMark3 receiverвЂ™s Vcc connection (+5Vdc). Your only remedy may be purchasing a new radio. These modifications are вЂtotally NOT factory approved.вЂ™ If you implement any of the changes in this document, you will void the factory warranty on your radio.

Mark Silver, KD7NKY Igage Mapping Corporation Дate: November 2009 Thesis: A simple modification for the ProMark3.RTK factory base radio which allows: ) placing the transmitter on a high pole, effectively quadrupling range: Urban ranges increases from 1,400 feet to 3,800 feet ) powering the GPS and radio from an external power source ) charging the PM3 base battery during operation, insuring the base is always operating at full output power Warnings (Please Read Carefully): 1.
