2WelcomeI’d like to share our thoughts and experiences of selecting the correct amateur radio equipment for field use based on a user profile and use case.
3Nick’s Use Case: Profile: Geotechnical Engineer travelling to remote locationsNeed a backup comm system while deep in the heart of nowhereRequirements:Communication range: kmPortable station able to be easily transported by commercial or chartered aircraft, helicopter or boat to remote field locationsFlexible power options:internal batteries120 VAC to 12 VDC power supplyexternal 12 VDC batteryPortable antennas: 2m/70cm, 6m to 40mQuick and easy to set up and get on the air!
4Yaesu FT-897D 2m/70cm 6-160m bands 100 Watts on 6m-HF bands50 Watts on VHF20 Watts on UHFOperating Modes: USB, LSB, CW, AM, FM, W-FM, Digital (AFSK), Packet (1200/9600 FM). Digital Modes: RTTY, PSK31-U, PSK31-L and User defined USB/LSB (SSTV, Pactor, etc.).
5FT-897D - Opinion Likes: Very rugged Internal batteries Fully featured Dislikes:Display is limitedMenu driven – more so than IC Not intuitiveYaesu antenna tuner has no extra CAT port for external laptop controlHeavy
6Power Ratings 2 Internal NiMH batteries 20 Watts for all bands when running internal4.5 AH – each batteryProvides about 4 hours of RX use per batteryUnder an 1 hour of typical TX use per batteryExternal 12 VDC22 Amps – TX1 Amp - RX
7Antennas Buddipole – 2m to 40m bands 2 traps with selectable band rangesTelescoping whipsMultiple configurations (see above)Tripod standSmall nylon zippered carrying caseEasy to transport – even as airplane check-in luggageEasy to set upUse an analyzer for faster tuningAntenna tuner recommendedRecommend inserting a 2m/70cm ladder line antenna for quick setup – very portable. Put into Buddipole carrying case.
8AccessoriesCD-24 internal battery charger – charges 1 internal battery at a timeOne end goes to a 12VDC supply – 1.4 AmpsWill charge from vehicle cigarette lighter socket12 VDC 30A power supply with Anderson Power PolesYoukits antenna analyserMakes the job of tuning the antenna quick and easy.
9Cables12’ 10AWG zip line DC cable with alligator clips for vehicle batteryCigarette lighter plug – for low current needs such as the internal battery chargerAnderson power pole ends
10Final Package – Ready to Go Radio and gear fits into a “Roots” carry-all bagThe bag fits easily into luggage or other check-in bagsAntennas fit into Buddipole case
11CARESS’s Profile:Have a set Grab’n’Go kits – always on standy and ready for use in case of an emergency or deployment at a remote event.Easy to transport and ready for any mode of operation:Voice, data, CWPowered by any available source
12Requirements: Fully self contained field unit Easy to carry Not as heavy and as large as existing Grab-N-Go kitGator case – rack unitRuggedFast deployment and setupPowerMostly external (battery or 120VAC)SLA 35Ah internalSolar panel and regulator for trickle charge (optional)
