Or "do I really want to repair this free radio?" In January an older ham I talk to said he had a bunch of old boat anchor gear (old tube ham and mil-surp radios) he needed to get rid of. If someone didn't come a take it away he was going to scrap it. So I drove to his place... 350 miles one way. A friend went with me and we loaded up the entire back of my Suburban with about 800-900 lbs of old radio gear... He lived about a stones throw from the ocean and this stuff was pretty rusty having been stored in a shed. Anyway, in the midst of this stuff was a newer marine band transceiver. Newer than 1945 but kind of old for synthesized solid state gear... The SEA222 transceiver hit the market in 1985 and was built and sold into the early '90s. Here's a photo of a nice looking SEA222 I found on the internet. All the boat anchor stuff was sold at a ham radio swap meet but I kept a few items like the SEA222 just to see if I could get it operational again. It had no display and no receive audio. Here it is on the bench. Fortunately Bruce (BTpost) had a service manual he loaned me. The display power supply has a filter made from two 22 uf 25v tantalum caps and a 420 mh molded inductor to keep the switching hash of the power supply off the DC supply. Well, tantalum caps are known for going bad and shorting out and they did. This stressed the inductor beyond it's limits and it opened so there was no DC supply to the switching regulator IC. Thus no display. I used a couple electrolytic caps in place of the tantalums with a .01 uf mylar caps strapped parallel across each one. Found a choke coil at 370 mh with heavier wire and figured that was close enough. Here's an after photo of the repair. Yeah, the two orange caps with the green caps on top and the PI wound choke between. Not real elegant but it works. Now that I got the display working I found that the problem with receive audio was just a jumper missing from the accessory connector on the back of the radio. I programmed the radio for 60 mtr Amateur channels and called the ham who gave me the radio. We talked for a while, he was impressed to hear how good it sounded. When I got off the air I noticed the keypad started getting flakey. Tracked the problem down the flex cable that connected the keypad to the main board. The flex cable was disintegrating and it's part of the keypad which is integral to the front panel laminate overlay. To repair the flex cable ment the keypad had to be replace which ment the front panel overlay had to be removed... Which I didn't want to do, at first... but I went ahead and did it anyway. Here's the keypad and overlay removed. You can see little holes in the conductive strips on the flex cable. So using some black sign vinyl and an aftermarket keypad I rebuilt the panel. Now things were coming together. Reassembled the radio and turned it on... the display now had the "UNLOCK" error code! Yikes! After studying the schematic of the dual Phase Locked Loop circuit I finally came to the conclusion that the CPU was not sending the data to the second PLL ICso it didn't know what frequency it was supposed to be on, this causes the PLL circuit to be unlocked. I contacted SEA Comm and they had a good used CPU they sold me and once plugged in we were back in business. Here it is on 20 mtrs. I even checked into the Maritime Mobile net on 14300 kc. The radio will receive by directly keying in frequencies on the keypad then pressing the ENT button. This is receive only mode. The receiver covers 500 - 24000 kc or .5 - 24 Mc. The transmitter works from 1500 - 23000. Transmit power is 150 watts peak. There are 100 user programmable memories. It transmits USB, AM & CW (with optional CW board). I plan on building the CW option board and installing it. There was also a LSB option but finding a LSB filter for 6.4 MHz IF might be difficult. I have less than $100 into the parts but the education experience gained I think is far more valuable. Plus I enjoyed repairing and modifying it. It's a hobby radio. Some of the newer marine band radios have both USB & LSB.. They are also getting easier to find and prices are coming down on used gear since a lot of ships are going sat-comm. They make a great backup rigs and are far easier for the uninitiated new ham to use. A good alternative comm radio for you monkeys! Especially if you don't have to repair it!
