It had a 1N34 diode, soldered right to the slug-tuned coil that the rod atop the “rocket” would tune, and a high-impedance earphone. Reply to a comment by : VE7ALQ on 2005-08-12 My first crystal radio was store-bought, with a coil in a red and white rocket(!).

From the drawing board of Warren Brune, W5OLY comes this superb HF amplifier. Mine, #462 was built in 1962 and still had the original 4CX-1000 installed. Had a couple easily corrected problems along the way in the form of metering diodes opening up. Replaced these with 1N34's in about 15 minutes and its working just fine.

K4DBC Rating: 2024-01-03; Nice Bang For The Buck Time Owned: 0 to 3 months. I had a Peter Dahl transformer go belly up in my Alpha 76pa so while it was off visiting Dick Byrd for the holidays I picked up a less than a year old 80b from a guy who wanted something solid state.

DJ3ZF Rating: 2022-02-13; Makes me happy! Time Owned: more than 12 months. For one year I'm the lucky owner of an Atlas 215x Limited Edition from 1979, which I bought from a collector who put it very early into the rack.

• Solid-state diode T/R switching — fast, silent T/R and QSK • Large convection-cooled heat sink for reliable and quiet operation • Modern design with rugged MOSFET output stage • Internal wide-range automatic antenna tuner (KXAT100 ATU option) with dual antennas • KXAT100 matches 10:1 SWR (5:1 typical on 160 m and 6 m);

The box for the Psvane tubes that was mailed from china was marked with “Description of item, One Diode, value 10 USD”. Before the update with the original Cetron tubes it put out 500 watts on 80 and 40, 400 watts on 20, and 300 watts on 15.

Vibration can break the legs to this diode (which puts full volts on the PA transistors base & they dont like it) however the insulation sleving can do a good job of holding the legs just in contact making it only a very intermit fault. I first noticed it when the O/P would "kick" from time to time. Checking all the voltages found nothing wrong.

K0PIR Rating: 2024-11-08; Overall, I highly recommend the Icom 7610! Time Owned: more than 12 months. I own the Icom 7610 and I am extremely impressed with its performance.
