1 Yaesu FT-897D Buddipole Antenna Portable Field Station VA7RLW - Richard Wodzianek VA7JFX – Nicholas Wodzianek November 2014Yaesu FT-897DBuddipole Antenna
2 WelcomeI’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.
3 Nick’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!
4 Yaesu 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.).
5 FT-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
6 Power 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
7 Antennas 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.
8 AccessoriesCD-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.
9 Cables12’ 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
10 Final 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
11 CARESS’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
12 Requirements: 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)
