I use an Icom IC-718 barefoot at home with the AH-4 autotuner and either a 300' wire antenna of stranded 14-ga house wire supported by Hackberry trees or a 31' vertical in an S-9 fiberglass pole. During thunderstorm season, a 20-meter dipole in the attic is used with an MFJ-949E tuner.
I enjoy operating portable when camping, traveling, etc. where I use an Icom IC-706Mk2G, the AH-4 autotuner and either vehicle battery, solar panels/battery, portable Honda generator or commercial power. My antenna is usually the aforementioned stranded 14 ga house wire pulled up by 3/32" black dacron cord over convenient trees, tents, bushes or lamp poles.
I also like to operate bicycle mobile with an older Icom, an IC-706Mk2, the AH-4 autotuner and a 102" stainless steel (CB) whip antenna on the luggage rack. I put the control head on the handlebars and plug in my single ear headset/mic and a handlebar-mounted push-to-talk switch. My power source consists of three 9AH sealed lead acid batteries hanging from the top tube and a battery booster to provide 100 watt transmit capability for a fair amount of time. I don't spend much time on the road, rather confining myself to neighborhood streets or dedicated bike trails. It is heavy and not built for speed but fun! I've had contacts on 15, 17, 20 and 40 meters with stations in Azores, Colombia, Cuba, France, Honduras, Martinique, Slovakia, Slovenia, Trinidad & Tobago and the US, to include an air mobile! I hope to work bike to bike when able.
Detailed pictures with captions on my bike mobile setup below.
Here's the bike with modifed luggage rack awaiting equipment installation.
Here's the autotuner mounted and connected. It bolts to the luggage rack. Pigtail connectors for antenna (red), RF from transceiver (gray), and auto tuner (black) are shown connected. Also visible is the power connecter at upper left (not connected yet).
Here is the tranceiver body (black) and battery booster (gray) mounted and connected (except) actual antenna.
This is the source of power - three 9AH sealed lead acid batteries in parallel and taped togther.
Here is the canvas pouch with batteries suspended beneath the top tube. Power connector feeds out the rear to the transceiver, tuner and booster stack.
Here is the homemade channel of aluminum that holds the control head of the transceiver. Also shown are the motorcycle push-to-talk button (left handlebar) and earphone and mic adaptor.
And now the control head is in place. The cheap computer headset/mic is also shown.
And here is the whole rig (less the antenna at rear or luggage rack.) Very heavy but built for fun not speed.
