Re: [Drakelist] Collins and Drake Compared

Drake was just the reverse of Collins, i.e., the majority of their business was with hams, with a small (if any?) government segment. Heath did somewhat the same, although they went a little too far, in my opinion, and ended up with a product that felt 'cheap' and flimsy, compared even to the Drake. Drake was not fancy, but WAS and IS solid in construction. Well put, Garey. I've personally always considered Collins the gear for the rich man while Drake was the gear for everyman.

This would seem to be a question of spot cooling vs. system cooling. I'll chime in with my $0.02 here... The suck it out versus blow it in debate (aka negative pressure versus positive pressure ventilation) has been raging for years in the fire service. When I went through firefighter training 25 years ago, the current wisdom was leaning in favor of positive pressure, but this has shifted a couple of times. These days both are in favor, but use varies depending on the space you need to ventilate. Generally, positive pressure is going to create a column of pressurized air with most of the effort going in one direction and is best for a limited space with few entrances and exits, whereas negative pressure will draw air from any place air can come from, and what you get is better although lower pressure evacuation of many spaces. I prefer negative pressure for my Twins and TR-4 as it can help draw warmer air from many places in the rig, not just the finals, although the finals are where most of the benefit will be found. It also limits the incoming dust being concentrated heavily in one location, which aids in periodic cleaning.

Personally, I like my R-4, and I like it a lot. Are there any others out there still in use...? I have one.

[Drakelist] Looking for TR-33c stuff
All; Does anyone have lurking about in the dark recesses of their computers an electronic copy of the manual(s) for the Drake TR-33c they might be willing to share? I'm also looking for a few crystals, specifically 145.270, 146.760, 147.060, 147.210 and 147.240 if anyone has any spares taking up space.

[Drakelist] R-8 computer protocol available?
All; Anybody have (or know where I can get) the computer control protocol information for the R-8? I love my R-8 (the original) but really would like to extend my capabilities, so I'm going to take a stab at programming again and try my hand at some code for the Mac. I've got the Developer suite (xCode, etc) but at a standstill without the computer control protocols. Thanks for any assistance!

They are abundant at hamfests, easy to fix (as long as the meter movement or cover aren't damaged) and typically cheap! The Simpson 260 is an excellent meter, but unless you get one of the very latest models they are only 20,000 ohm / volt sensitivity. This is usually not a problem, except when it comes time to measure a high impedance AVC circuit in a tube receiver. Then the 11 Megohm input impedance of a Heath VTVM is handy! I concur again... I have one of the Heath VTVMs but don't use it too much; sure is handy to have around when you need it, though.

There are LOTS cheaper meters, but none much better. The biggest deficiency in the cheaper meters is that lots of them are very low input impedance. Absolute accuracy is really not all that important for 99.9% of what you will use it for, but low input impedance can be a problem, especially if you are working on tube type gear. Look for at least 10-11Megohm input impedance. I second the Fluke DMM recommendation, and have another to add... Look around for a good analog meter to add to your workbench; they're very, very useful to have around as well, especially if you're doing any kind of fine receiver tuneup. It's much, much easier to detect minute swings of a needle as opposed to the often constantly bobbling numbers on a DMM display. I highly recommend the Simpson 260. I picked up a near mint Simpson 260 Series 6P, complete with the original Bakelite case with roll-up door, for $50 at Dayton a couple of years ago, and it has made receiver tuneup so much easier. I had almost forgotten how nice it is to use a really good analog VOM... The real bonus is that the Series 6P and later models used one D cell and one 9v cell as opposed to one D and four AA cells. Much easier to change batteries, although that wouldn't have stopped me from buying one of the earlier models.

The closest thing they have that is reasonably priced is the phillips head version for which I paid $5.28 for a box of 100. And the Phillips head version wins by quantity 99!!! Personally, I'll go with the Phillips version. While a straight-head screw is original, I'm not too concerned about that for a rig I use every day; as long as the cover stays on and the screw looks reasonably correct, I'm a happy camper.
