Rockwell Collins MP1 mobile power supply restoration & upgrading for MOSFET use
zhlédnutí 210Před 8 měsíci
This video shows the Collins MP1 mobile power supply, and how to restore it. The MP1 was sold by Collins Radio Co. from early 1960s to late 1970s. It allows the user to operate the tube-based Collins KWM2(a) and KWM1 transceivers mobile from a car battery. Most of these MP1s are not usable any more after more than 60 years due to deteriorating electrolytic capacitors which leakage often also co...

This video shows the vintage NEC RF power transistor type 2SC1306. The 2SC1306 is a vintage transistor in TO220 package that was used widely as the RF power transistor in CB equipment, from the mid- Seventies up to the late Nineties.

    Great video. I would have liked to a see CW demo but still a fantastic demo. I believe this was the transmitter in the bombers paired with the BC-348 I. The early part of the war and eventually replaced with the ART-13. I have a BC-348-R. It’s a single conversion with 2 RF staged before the mixer and 3 IF stages after the mixer at a freq of 915 for the IF. The CW key used in the bombers with this transmitter was the J-5-A flame proof and I have one in absolute mint condition. 73!!

    • @LifeIsTooShortForQRP
      @LifeIsTooShortForQRP Před měsícem

      That is correct for antennas that are resonant. When an antenna is not resonant (which is almost always the case for this transmitter in an aircraft having a trailing wire antenna), there can be a large component of current that does not take part in delivering actual radiated power ("out of phase" current, also called "bad SWR"). This is the part of the RF current that the built-in antenna tuner needs to cancel out. But the RF ammeter cannot distinguish between such resonant currents and "blind" currents, and will therefore show a large current going into the (non-resonant) antenna depending on the impedance of the antenna (which on it's turn is frequency dependent). Think of it as the power factor that applies to the AC grid. An inductive load (or capacitive load) will show a large current going in that does actually not dissipate any power in the load. That translates to a power factor of 0, and won't make your outside kWh meter move. A purely resistive load (like an incandescent light bulb) will exhibit a current going in that DOES deliver actual dissipated power, and the power company will charge you for that one. That is a power factor of 1. Anything in between (like an AC motor) will be a load that is partially resistive in combination with a partial inductive (or capacitive) load. It is the same for the antenna that forms the load for this transmitter, but then at a much higher frequencies than 60 Hz. But the concept remains the same.

      228 / 5,000 Yes, that's right, the manual explains it (you can download the SL20 manual from the web). It is one of those small jumpers encased in plastic, which they often used for computer hardware in the old days. If the jumper is removed, the power supply is "softer". All you have to do then is adjust them all for the exact same voltage (without load), and when putting them in parallel. Use the same DC wire length for all 3 power supplies. then the current will distribute nicely across the SL20 supplies. 73s.

    I remember when this radio came out. Back in the late '80s, when the FCC totally revamped the rules and created the novice voice class that allowed novice operation on a small segment of 10 meters. That's when I got my novice license, but I immediately got my technician license, bypassed 10 meters, and went straight to 2 meters. Radio Shack later came out with a 2 meter handheld, the HTX-202, but never had a 2 meter mobile.

  • @spaceflight1019
    @spaceflight1019 Před 2 měsíci

    The caveats with this generation of radios, and I own a Yaesu FT-225RD, are these: No built-in CTCSS. If your local repeater is on tone squelch you're not going to be able to talk through it. No memory channels. The radio is controlled by the VFO. No scanning feature. If you want to scan the band prepare to spin the big knob! Low power. Most of these put out only 10 watts, as it was common practice for them to be used with a linear. If you have no technical skills, don't buy one. After 40+ years they will require some attention and the OEMs and radio shops won't touch them due to the age. But if you can live with all that... you can get a very good price on them at hamfests. Happy hunting!

      It highly depends on condition, serial number and installed options. A nice KWM380 in good cosmetic condition and no corrosion, but without any options and with serial number above 700 can be close to $3000. All options installed and good condition (like a HF-380 version) can go for more than $7000. A raggedy KWM380 with a serial number below 300 is probably more in the $1500 range. Hope this helps.

    Ah yes, the old 40-channel Hy-Gains. I converted several to 10-meter FM back in the day. Forget the procedure for the band conversion, but I sourced the FM front-end kits from Bob Heil. Didn't know the 2SC2166 prices had risen above a dollar so I just checked eBay - the first 2166 I ran across was listed for $84. Good grief! You performed a good test for confirming authenticity of the replacement transistor, but shouldn't it be possible to compare the replacement using a transistor checker for equivalent values, especially the hfe?
