Baldy Mt. Electronics Site Summer of 2007 Work Season Progress Report

GENERAL SITE TASKS

Done:

Surveying

Northeast corner of the Jove Lode was found to be in a favorable location vis a vis the possible relocation of the New Head-end.

Main Shack door replacement

The new door swings inward and seals very well.

To be done:

Seal openings under Main Shack.

Deferred:

Old Structures removal

Paint Ham Shack

AC POWER SUPPLY

Done:

206 SCR 532 Electrical Service Pedestal renovation

Main Site Disconnect Switch repositioning

3/4" Electrical Service Conduit installation

Main Shack Power Line Entry renovation

New Head-end Electrical Service renovation

To be done:

Individual load measurement

Deferred:

Power line fault analysis

Burying of exposed electrical conduit

TOWER WORK

Done:

Permanent Tower C installation

Wispertel Repeater Units repositioning

KTUN and KLDV receive antenna mount installation

Temporary WISP Antenna Support Structure removal

To be done:

“Apex” repeater antenna repositioning

KTUN receive antenna repositioning

KLDV receive antenna repositioning

KUVO STL receive antenna repositioning

Deferred:

Tower A West Guy-wire replacement

OLD HEAD-END WORK

            Temporary ground fault repair resolution

Addressed by the installation of a dedicated 3/4" Electrical Service Conduit (see AC Power Supply group above).

To be done:

            Trans-ridge Conduit repositioning

220 volt to 120 volt Power Supply Auto Transformer reinstallation

Deferred:

Trans-ridge Conduit renovation

NEW HEAD-END WORK

Done:

KVOD & KUNC Receive Antenna Position Swap

To be done:

Possible Repositioning of Support Structure

MONITORING & CONTROL SYSTEM

Deferred:

System Assembly and Installation

UNINTERRUPTIBLE POWER SUPPLY

Done:

            Photovoltaic Panel Array Support Structure creation

Concrete columns poured

Battery Rack fabrication and delivery

To be done:

Photovoltaic Panel Array Support Structure creation

Treated 6’ x 6’ wood horizontal members installation

Deferred:

Wind Turbine Generator Support Structure installation

System Assembly and Installation

TV AND FM TRANSLATOR TASKS

Done:

Translators Station-identifying label creation

To be affixed.

New KUNC translator installation

To be done:

88.3 KUNC Output Bandpass Filter Installation

The filter is in place but is introducing a high SWR when it is connected.  Note that the KUNC FM translator itself is interfering with the Channel 4/8 TV translator video signal (fine herringbone pattern).

Channel 8, 10, and 12 TV translator relocation

107.9 KLDV Output Filter Installation

89.7 KUVO Output filter replacement

Deferred:

89.7 KUVO FCC power increase request

Possible replacement of KLDV omni-directional transmit antenna

94.3 KBCO Output Filter Installation

KUNC KU-band satellite downlink installation

            This may not be necessary.

Baldy Mt. Electronics Site Conditional Use Permit

 

A meeting was held with Brad LaRochelle of the Summit County planning Dept. at which time the revised map showing the New Head-end in relationship to the Jove Mine Claim was hand delivered.  The creation of a lease agreement between Summit County and SPR was discussed.  The permitting process will be reinitiated in September.  An amendment to the Conditional Use Permit application to include placement of the donated building-on-skids on the Jove mine claim near the New Head-end antenna support structure will be made at that time.

FM Translator Updates

88.3 KUNC/K202CV

This FM translator is functioning well using the new translator received from KUNC.  An output Bandpass filter is in place but is not hooked up because it introduces a high SWR when connected.  Note that the KUNC FM translator is involved in an interference problem with the Ch. 4/8 TV translator video signal (fine herringbone pattern).

89.3 KVOD/K207CK

 

This FM translator is functioning properly. 

 
89.7 KUVO/K209ED
 
This translator is functioning well, using the digital audio stream available from the KUVO website and the MS MediaPlayer stream player.  The remote control, which failed in August, has been repaired by Jeff Kamis of MacCentric Computer Service.  The instability of the digital audio stream that feeds this translator continues to be an ongoing problem.  A working committee organized specifically to address this issue is most strongly recommended. 

94.3 KBCO/DK232AC

This FM translator is functioning properly.

95.3 KTUN/K237BI

This FM translator is functioning properly. 

107.1 KUNC/K296CL

This FM translator is functioning properly. 

107.9 KLDV/K300AE

This FM translator is functioning well.  An output Bandpass filter has been received but is not yet hooked up.  Note that the KLDV translator is involved in an interference problem with the Ch. 4/8 TV translator video signal (fine herringbone pattern).

TV Translator Updates:

Channel 8 KCNC‑4/CBS/DK08MN

This translator is receiving interference from the KLDV and KUNC FM translators adversely affecting the TV picture quality.

Channel 10 KMGH‑7/ABC/DK10ON

This translator is functioning fairly well.

Channel 12 KUSA‑9/NBC/DK12PF

This translator is functioning properly.
