    Encrypt everything. Even if you have nothing to hide. It increases the noise floor.

    shit, you should move here. $14 a hour here and you could live like bill gates.... ok maybe not like bill gates but you would have it made. AND with the crime around here you would always have busy shifts with all the shootins,stabbings,drugs,ect,ect

    "Yeah. Her name is Shirley and she likes it rough."

    Sounds like one of Rudi's friends.

This takes a lot of space but you make up for it with greatly reduced EMI/QRN near-field levels. Of course, most of us are stuck using a mains-driven DC supply due to these constraints but if you have enough room for a bank of 4-8 100AH deep cycle batteries you can connect them to a supply through a charge controller (such as the unit offered by West Mountain Radio) and have yourself a nice little auto-failover DC setup.
    I have 18 90AH deep cycle gel batteries stored, use 'em for camping and loan them out to locals for FD and such. Charge 'em up every 4 months, they only take 3-4 minutes to top off at 1 amp or less. Surplus pulls from work. I have more available soon. Really need a budget for solar/wind power. I get the batteries for free.

    The West Mountain unit is sitting here, new in the box. Not enough time for projects. Sigh.

    It really does help the noise level. Was not noticeable living in the city, but living here, the noise floor drops.

    I use one of those RadioShack wonders to charge 12 volt items in the garage - but not car batteries. I used it to charge my FT-817 for a while. I typically use it recharge the small 'jump' batteries I use in the winter.

    I have two of the Astron Rx-35's one M model, one S model. I have had the M model with the meters in use continuously for about 40 years. I bought the S model for $100 on EBay, and it's been turned on for me for several years. I don't know how old it is, but it is an older model. I've never had to fix one (knock wood) but I'm confident that the copious quantities of online documentation on troubleshooting them and availability of most parts, I would not have a problem doing so.

    Now, having said that, I don't think the MFJ supply proposed looks bad at all. Unless you're doing real weak signal work, you'll probably not notice that it's a switching supply, and switching supplies usually fail in a 'safe' mode that won't harm your gear. The analog supplies can easily die in a fashion that puts out too much voltage if the over-voltage circuit isn't done correctly.

    Still, owning an analog Astron is like owning a 'piece of the rock'. And it will weigh like it, too.
