view of the North side in image below: windribbon (t); (b) treeharps networking

Conceptually I wanted to simultaneously hear all of the installed Terrain Instruments at any given time and all the images on these pages are but details of the original Permanent Forest Terrain Instrument whole . I was not able to do this in realtime. Reel-to-reel analogue and video recordings were made and the individual instruments were Nagra 4.2 recorded. On this page was the site from which satellite performances originated. Realtime resources, recordings and remotely telephone-controlled Terrain Instruments constituted these 2-way interactivities.
&IMAGE
Above and
below
V.1 is shown in two connected but different
locales. Hefty turnbuckles hold the pair via a U-shaped steel
rod: below image- windribbon is paired with a 9 gauge galvanized
steel strand... windribbon is at back back with the 9 gauge strand
faceing outward...each monitored wind and torsional tree movements...


The wire pair from below... The're anchored to another distant birch tree. For the duration of its sounding life ('75-'86), this tree was referred to a Major Birch. It served as the main anchor for combinations of multiple strand configurations and served also as the anchoring live flagship-soundsource during realtime and interactive Westar satellite (and for teleconstruct spaceworks) projects. The tree succumbed to bronze birch borer disease in 1988 several years after a nearby tree fell and brought down this v.1. The vertical aluminum tube in the 2nd top image was (part of the terrestrial whistler(s) and was physically attached to the 9 gauge strand which parallels the windribbon.. (Producing combind hums and whistles from the same wind gusts).
DETAIl: pair of turnbuckles grasped
and held the windribbon taut. Tied down and wrapped outward onto the first
inches(this shared the tension at the crutial point)
also you can see an additional 9 gauge steel
strand which ran parallel.

recap
1987 windribboning
68dragged Maple leaf

The fat blue
cable shown in both pictures carried the amped and line-level
output into a nearby basement soundroom. Sensor inputs are the
three RCA females dangling from the bottom (with one still attached).
A nearby solar panel supplied the DC for the preamp and amp outs.
An attached FM transmitter (above photo: box is tie-wrapped to tertiary limb) and allowed for nearby FM radios to overhear sound collections from this listeningsource. FM radios on nearby London Road were able to tune into the Major birch.

| Each of the trees shown below had the following hardware: |

|
|
| 2-dual channel FM transmitters. ((could be heard w/in a 1/2 mia area)) |
| 6-DC/FM radio receivers shared these line inputs-via
a basement sound room- into a pair of SHURE M67 mono mixers and
output was cabled to a 3rd dual FM transmitter located atop the
roof chimney. NOTE: there are quite a few vacant and quiet holes on the FM band in Duluth Minnesota USA) |

The Douglas Fir
(l) and Birch sounded like regular trees when wind-stirred. In
each the trees primary, secondary and tertiary limbs a/or branches
and the main trunks were monitored. Trees acted like an antenna because
of grounding faults in the pre-amps (hum, accompanied by rf and
internal vibrations The fir allowed me to hear German and French
broadcasts. Right

over the house roof to another tree where a receiving parabola
passed the trees amplified vibrations, via shielded audio cable,
