VOTE: $2k budget for Haystack site hardware
Hello, I'd like to propose we allow spending of up to $2k to cover the costs of installing a photovoltaic (solar) power system @ Haystack. The site owner has allowed us to host a site up there as long as it doesn't impact their power budget. The site is not wired to any utility power, and transporting propane to it is expensive. This is a 1-time cost, and the hardware will remain property of the site owner. In exchange they'll be giving us new mounting points for 2 dishes and 2 sectors, which will have a huge impact on coverage and extending the network. Our recurring cost for the site will be $0/mo, which is an ideal long-term arrangement.

Bart, I concur. Haystack sends a big signal into Kitsap County. I am sending a donation of $101, which is on top of my monthly donation support.

As a board member, my official vote here is YAY. Dan, that is the plan and expectation. The two dish mounting points described in Bart's original message will be used as part of the backbone of the network, and the two additional sectors will fill out our 360 degree coverage for that site (adding to the existing 1 sector installed at the moment). I'm not certain at this point which sites we'd like to aim at for connectivity with those dishes, but I suspect that Paine will be one of them, as it should be well aligned with a dish we have on site already. The other will need to be determined for where we can best support the link from, or where we're likely to expand to.

My official vote is also in the affirmative (YAY). That gives us enough board votes to pass. This will be a great addition to the network! I will also match Dan's $101 donation and any other donations we receive in the next week up to the amount that would allow us to pay the HamWAN credit card off right away. -Cory NQ1E
To get this straight, this vote is for power systems at Haystack only. HamWAN modems, antennas, mounting hardware, cable, etc., will need another vote. Is this right? I have moderate experience with solar systems, and some of the line items don't make sense to me. - What is the Meanwell 24V->12V converter for? The modems run on 24V. What do we need 12V for? - What is the IOTA AC->24V converter for? I thought we didn't have AC at the site. Also, it's available from a seller on Amazon for $150 less than quoted. - Why is there no MPPT charge controller? Or batteries?

I was going to ask about the lack of batteries on the list as well. Is this just to add addition charging capabilities to an existing battery bank? On Sat, May 3, 2014 at 3:11 PM, Tom Hayward <esarfl@gmail.com> wrote:

I presume you all know that the 5SPHn radios run on 8-30 vDC. I'm running mine on 14.2 vDC from a WestMountain RigRunner, and the current draw is miniscule. My understanding for the 24 vDC wall wart supplied with the radio, is for voltage drop in long Cat-5 runs.
I will let Bart speak to the specifics of the converters, but yes, this is an addition of a panel to supplement the existing panels and batteries on site, to offset our power usage. In summary, we are adding capacity to their existing system, rather than creating our own power system. Nigel K7NVH On May 3, 2014, at 4:39 PM, Dean Gibson AE7Q <hamwan@ae7q.com> wrote:

This is for the power system only. The other items for Haystack have already been purchased, so there's no spending request there, and no vote needed. We are expanding an existing power system. They have an existing battery bank and full solar system. We're mostly adding some panels. I'm not sure what the 24->12 converter is for. I don't have a schematic of their electrical wiring. I suspect the AC->24 converter is so we can interface power from a gasoline generator they have on-site. It's remotely controlled, and can be engaged when the battery bank gets too weak. I'm not sure what the MPPT controller story is. I already asked about this. Thanks for finding the AC->24 converter cheaper. Are any other items here available cheaper? Can you provide bottom-price URLs? I'll work with them to understand the solar system better, make sure we're gonna be running @ 24VDC and that we're doing things sanely. From what I've seen of their engineering + setup, they're competent folks. It would certainly be nice to get a better understanding of the power design these parts will embody. --Bart On 5/3/2014 3:11 PM, Tom Hayward wrote:

This is for the power system only. The other items for Haystack have already been purchased, so there's no spending request there, and no vote needed.
We are expanding an existing power system. They have an existing battery bank and full solar system. We're mostly adding some panels.
I'm not sure what the 24->12 converter is for. I don't have a schematic of their electrical wiring.
I suspect the AC->24 converter is so we can interface power from a gasoline generator they have on-site. It's remotely controlled, and can be engaged when the battery bank gets too weak.
I'm not sure what the MPPT controller story is. I already asked about this.
Thanks for finding the AC->24 converter cheaper. Are any other items here available cheaper? Can you provide bottom-price URLs? I'll work with them to understand the solar system better, make sure we're gonna be running @ 24VDC and that we're doing things sanely. From what I've seen of their engineering + setup, they're competent folks. It would certainly be nice to get a better understanding of the power design these parts will embody.

To get this straight, this vote is for power systems at Haystack only. HamWAN modems, antennas, mounting hardware, cable, etc., will need another vote. Is this right?
I have moderate experience with solar systems, and some of the line items don't make sense to me.
- What is the Meanwell 24V->12V converter for? The modems run on 24V. What do we need 12V for? - What is the IOTA AC->24V converter for? I thought we didn't have AC at the site. Also, it's available from a seller on Amazon for $150 less than quoted. - Why is there no MPPT charge controller? Or batteries?

Hello,
I'd like to propose we allow spending of up to $2k to cover the costs of installing a photovoltaic (solar) power system @ Haystack. The site owner has allowed us to host a site up there as long as it doesn't impact their power budget. The site is not wired to any utility power, and transporting propane to it is expensive. This is a 1-time cost, and the hardware will remain property of the site owner. In exchange they'll be giving us new mounting points for 2 dishes and 2 sectors, which will have a huge impact on coverage and extending the network. Our recurring cost for the site will be $0/mo, which is an ideal long-term arrangement.
Here is a list of the hardware required:

In the $2k request, I'm also allowing ~$250 for shipping costs. Solar panels are large. Anything not spent will be returned to the HamWAN budget.
We already have all the other hardware required to deploy the site in-stock. Some of it is already deployed (Haystack-S3), and some is sitting on-site (modems, 1 dish, other sector).
Our present balance is $1,291.04, so we'd be going into debt for this deal.
The other cost of this deal is recognizing the site owner's sponsorship of HamWAN by including their logo in presentations, and offering some man-hours for site maintenance. The big project this summer (aside from this solar system install and the full HamWAN site install) will be helping with installing a grounding system there.
My vote on this deal is: YAY.
