DEMI has just unveiled their new WSSA-M tunable Weak Signal Source based on the apolLO-32. Previously, to get a weak signal source it was necessary to buy one per band. This new DEMI product built on the apolLO-32 has a rotary switch allowing you to select up to five of the preprogrammed apolLO-32 frequencies. There is also an internal option to use a on-board TCXO for a completely self-contained signal source. The frequency list is available in the documents section of our website here.
Details on this and the other weak signal sources from DEMI can be found on their website and in this flyer:

The unnamed dish pointer project won a 2nd place finish in the annual SVHFS design contest last weekend. The dish pointer has a 3-axis accelerometer and compass for sensing the absolute position of a dish as well as a pair of H-Bridge drivers to run linear actuators. An LCD shows the position of the dish and has the menu lines for the buttons (not shown). The sensor/drive mechanism are separated from the control by a pair of Ethernet cables. I’ll be working on this guy for the next few weeks and I’ll put some more info up here when the software is more complete. Stay tuned!

The website was displaying some PHP junk from sometime on Saturday 4/25 through this morning. It was caused by an error in the vendor we use for a shopping cart and it crops up from time to time. FYI, we use the shopping cart simply to prepare an order for products and then we transfer the order to Google Checkout. Google is responsible for collecting payments and we never touch the actual payment information. I have run a full-up ecommerce site before when I owned another business and it was routinely the target of hacks. None were successful, but I did spend considerable time monitoring it and with someone else to do it for a small fee (Google), it was just the right way to go. It allows me to focus on electronics and you know your card information is safe with the big boys.
