    I spoke to one of the KATU engineers at about 9 PM who confirmed they were having problems. But now I am watching Hogan’s Heros at 10 PM so all is well!

    To bad I couldn’t convince them to make it an HD system!

    Regarding the increase in signal strength for Hillsboro, I suspect there are 2 things helping for increased signal:

    1. I completely rebuilt (re-wired/re-plumbed) the RF output switching and the how it was feeding power to the ATU. The way it was done prior to this was not as good IMO.

    2. I suspect the audio was not modulating very well before, I have it running at 100% now during this phase of testing. Next week I will re-adjust it for 125% on the positive peaks & re-evaluate.

    Special thanks to Randy Pugsley for helping with the KBAM audio processing – which is still a work in progress.

    Just a few months ago OPB laid off ALL their field engineering staff in the Portland area in favor of having studio engineers handle any field problems that come up.

    Oregon Public Broadcasting did NOT forward today’s NPT on to their FM audio chain. Apparently they are looking into the matter. That is a little embarrassing since OPB also failed to forward the last test 4 years ago.

    There is occasionally live people on KSLC. I just installed a Comrex for life remote broadcasts at KSLC.

    I can often get good reception in my car of KSL-AM in HD!

    I did not install the KBAM translator – it was done prior to my arrival. The KBAM translator should perform nearly identical to the KEDO translator. They are both mounted on the same tower with similar antennas close in elevation.

    the translator is licensed for 250 watts ERP and is using a C-pol antenna mounted to the KBAM tower.

    When I left KBOO I was in negotiations with KPDX to lease from them for $500/month and they would use the tax credits from KBOO to get a break on their property taxes for renting to KBOO. (at that time KBOO was paying about $2800/monthly to rent at StoneHenge)

    I heard that after I left KBOO halted the negotiations with KPDX because a board member said it was improper to allow a pro profit corperation to not pay taxes simply because they are renting to KBOO. 🙁

    In about 2009 I recommended KBOO replace their Dexstar with a Flexstar for about $28,000. This primarily would have been to support HD2 & HD3 but also update the digital part of the system. I had a Russian group willing to pay $10,000 up front and $1000 monthly to lease KBOO’s HD3 at 24K bandwidth for 2 years. This would have provided an HD2 channel for KBOO and $1000 monthly income to pay off the remaining cost of the Flexstar with a little left over.

    (at that time the KBOO Dexstar was about 5 years old – I installed the KBOO HD system in June 2005)

    The KBOO board of directors refused to approve the purchase of the Flexstar and refused to negotiate any agreement of leasing out an HD channel. One specific board member was leading the charge against it stating that KBOO should operate both the HD2 & HD3 channels themselves and raise funds for the Flexstar privately.

    Now, 6 years later, KBOO has never had any digital channels other than the HD1 and currently that is off the air because the Dexstar (which I recommended replacing in 2009) has failed. $1000 monthly income would be welcomed by most Community stations.

    I put the 99.1 translator for KEDO on the air about 3 weeks ago. We are working on some antenna issues and getting a 950 MHz STL to improve the audio quality. At this time it is being fed by a subcarrier on an STL.
