Re: [time-nuts] S743 Marketplace Fariness Act... and freq standard box
What I read is that it is for merchants who exceed a million dollars a year. So, if it is determined it is each seller that is responsible, it would only apply to those doing greater than a million in sales (not many). If however it is determined that it is ebay who is the merchant, then they would have to handle the tax collection and payment and it would simply be added to the final auction and maybe plus shipping amount (depending on the state and what is taxable). This is the most likely scenario. It is more complex than just what tax rate to use as each state taxes different things. For example, some states do not tax clothing, others do, and some others only if the item exceeds some cost. As I mentioned in another message there are third party services which keep track of all this already. For a site like ebay it is complex but not daunting task to set that up. I will spend my time worrying about how I am building my combo Rb and Thunderbolt box. I have a TADD-1 amp in there, pulse stretchers to drive front panel 1 PPS live indicators, a serial to IP adapter to give the box network connectivity (mainly for the Thunderbolt but switchable to the FE-5680A). I have a fan setup in an isolated section (it is built into a 2U rack box) for the TB so LH can help with temperature, but I'm not sure if I should use a computer to discipline the Rb or just set it close manually every so often. And which should I feed into the TADD dist amp? The Rb? Initially I'm just putting a switch in so I can select. I'd love to hear comments on this. I can post photos of where I am at in the construction if anyone is interested.

In any case the congress IS considering such a law. In essence it forces all internet sellers to collect the sales tax due in the buyers state. If you live in a state with a law requiring that sales tax be paid on all out of state purchases (internet or not), often called a use tax, as the buyer you are required to pay this tax. The taxes already are on the books, they are often not enforced. You can learn all about this with a Google search which will reveal all sorts of opinions. Here is one that is not too bad: http://www.forbes.com/sites/beltway/2013/04/23/five-things-you-should-know-about-the-long-overdue-online-sales-tax-bill/ If you already comply with the law and do a lot of internet purchases; passage will relieve you of a pain in the ass accounting job at tax time. If your state has no such tax or if you avoid paying it, though your state requires it, passage will cost you some sale taxes you would have otherwise escaped. One nasty consequence is that the software to pull this off is non-trivial since local sales taxes in many states vary by county, school district, local bond issues and so on.

Re: [time-nuts] S743 Marketplace Fariness Act
And the funny thing is that there is already legislation in place to deal with this. If an online vendor has a corporate office, a warehouse or a brick and mortar retail store in State XX (that has a sales tax), AND if an online customer places an order to be shipped to an address in State XX, the sales tax for State XX has to be charged. I live in WA State and buy online from Amazon (corporate headquarters as well as warehouse) and I get charged the WA State sales tax. I buy online from Fry's (just a brick and mortar store) and get charged sales tax. Parts Express (great company) - no presence in WA State so no sales tax. If I walked into Parts Express's corporate headquarters in Ohio and purchased some stuff, I could show my WA State drivers license and be exempt from the Ohio sales tax. Why is this any different from an online purchase?

Re: [time-nuts] S743 Marketplace Fariness Act... and freq standard box
Peter, I believe you are correct about the $1M per year trip point, but would remind you that this is a very slippery slope. When the Income Tax was originally enacted, very, very few were impacted. That is no longer so. The Alternative Minimum Tax was enacted to hit those who have saved and invested already taxed once money, and hit them again. Yet over the years the AMT has hit more and more in the middle class, so Congress has had to enact annual 'fixes'. The Capital Gains tax is on assets that have increased in value, but there is no provision to index the CG taxes for inflation. So, the fed inflated the currency, and taxes virtual growth. This is fundamentally not about 'fairness'. It is all about government at all levels wanting more and more money, ultimately to buy votes, by playing Santa Claus with other peoples' money. The 'fairness' argument is all about the politics of envy and getting re-elected. YMMV, -John == What I read is that it is for merchants who exceed a million dollars a year.

Re: [time-nuts] Radio with GPSDO
In a world of digital comms with very capable competition, AOR has been looking for a reason to exist. They have turned to high end gear. For some time now, their radios were DDS and capable of running from an external 10MHz. I suspect they are used in a rack of gear to direction find. The black box SDR version is the next obvious step since nobody was actually playing with the knobs anyway. I would be surprised if there were vans with 3 or 4 of these black box radios as part of a stingray or silent ping set up using correlation techniques to RDF cellular users. It has enough bandwidth to cover all known cellular providers.

[time-nuts] Trimble ACE Replacement?
I'm sure some of you noticed the flood of Tymserve 2100's on eBay lately, they were selling in lots of 3-4 (or more)! I managed to pick up a few (like I really needed them) and proceeded to add in the GPS module to make them a little more useful. I haven't seen any Trimble ACE receivers on eBay in a while. I was doing a little research and while the SveeSix seems the same physical size and pinout, its COM settings do not appear to be adjustable (I could be wrong), but even the simple act of switching between like TSIP NMEA requires re-flashing the receiver, there was no mention of changing the comport settings in the documentation. So I started looking at the Lassen modules since that came after the ACE line. They too appear to be the same pinout, however their physical size is different. They come in both 5v 3.3v flavors, and I managed to find someone on eBay selling a 5v one. My question is, has anyone tried to get a TS2100 to communicate with a different receiver than the ACE line? Kind of curious what works and what doesn't. I did manage to get an Oncore UT+ off eBay for 1 cent (plus $8 shipping)...
