The circuit board for the rebuild kit mounts on top of the chassis. You can also do a 1 for 1 replacement of the capacitors with cans, which is more expensive but preserves the original layout. If you

I don't understand the 'cage' thing. There a solid metal plate over the bottom of this PS. Thanks

Regarding the "klunky" interface on kiwi SDRs, you might be interested in the Youtube video "VK2MB KiwiSDR Secrets." It's long (90 minutes), but it shows a whole raft of things that are available on

As a side note, some prefer the AC-3 over the AC-4 due to the "open air" sort of cooling while the AC-4 has a small number of "hot air exhaust slots". ? I have no personal experience with the AC-3 so

I would simply go ahead and re-cap this supply. Paper bodied electrolytic capacitors are prone to dry out. If you want to wait, replace just the bias supply’s capacitor, as if you lose your bias

I accepted a trade offer of a TR-4 for my troublesome TR-3. Opened things up and have a few questions for those in the know ... Images here: https://kd4e.com/kd4e-html/drake-ps The power supply has

Thank you all for great comments and qwik replies... securing a deal is just as good as turning a questionable one down...so TU! From what I can see, there are bundles of questionable devices/sellers

Received a replacement (MC14560B) for the BCD adder IC (ref. U32015) that sits between the 100s kHz counter and the 100s kHz display driver on the VRTO Digital Board today. Installed it on a socket,

I have in my collection of “stuff” two Drake AC3’s. One is a really early version and the other is a later version with a lot of iron. My question is, are all AC versions capable of driving all

I've used some of the Kiwis on the internet when a signal I am chasing is below my noise floor. They work OK but the interface seems a bit klunky. My LAN-IQ will work standalone with an eye catching

That's a subjective question. It depends on your use case. I would like faster scan speeds, lower RBW, higher maximum input level, and direct access to the internal storage as a USB device. Other

I've used my L4B on 17 and 12 meters using both SSB and digital modes using low plate voltage.? On 17 meters with the bandswitch set to 15 meters and about 50 watts drive I get about 500 watts out.?

Jim, Could you pass on what you feel are the important limitations. A display with over 70 dB of range and an RBW of 200 Hz seems good for a <$200 unit. Bill N0CU [email protected]> wrote:

Yes. I used some Gates 4219XL, bought from O'reilly's, 3/8" id and about 5/8" od, hose to make a bushing for my TR7 PTO. I haven't had to replace the bushing on my TR5 yet, so I don't know if it's the
