Electrical parameters:

The small needle nose pliers that I use for this had to be fashioned with a Dremel tool and high speed diamond wheel which I used to get a rounded surface for the side of the pliers jaw.

Without this remodeling, the flat surface of the jaw and the sharp angle at the side of the jaw leaves a crimp in the copper arm holding the contact. This crimp damages the arm and eventually causes the arm to fall off with the repeated flexion that comes with the operation of the relay. With all the contacts openly exposed they are physically cleaned with a soft brass brush and the high speed Dremel tool until all the foreign matter is removed and the contacts are made bright and shiny.

Now comes the hard part. The copper arms holding the contacts which have been splayed back have to be gently returned to their original position and tensioned for proper force. I do this by hand and it is a very time consuming and exacting endeavor.

When this is completed the unit goes for its first gold plating. For half of the gold plating session the arms are held in the open position to get those contacts plated. The unit is again rinsed and dried before the conditioning process is started. I found that this is necessary to reform the contacts since no matter how carefully I reposition and tension the arms the fit may not be perfect.

This high current during the make and break cycle heats the metal of the contact and deforms it so that it fits precisely to the matching opposite half. Too few cycles will not give a good fit and too many will permanently damage the contacts.

This information is proprietary so we will go on to the next step. The unit is now replated for all four contacts in the gold solution bath so that the previously heated portions of the contacts from the conditioning process also gets a proper plating.

The unit is again dried and the top replaced. But you cry are we finished.

The answer is not yet. The last step is quality control where the unit is placed on a milliohm meter and cycled 50 times per contact. No one reading on any contact can exceed 50 milliohms. For this auction and in my own repair work a special gold plated socket will be supplied to be installed so that if a problem occurred, the relay can be removed and replaced without dismantling the radio to unsolder it.

However if you are brave just solder it in place as I am confident it will be and stay good. Relay 02 is in close proximity to a transmit mixer that runs continuously in receive as well as transmit.

That circuit is in the middle of the RF board inside the metal baffle on the upper side. Because of this other circuit the relay was meant to be flat to the surface the board to reduce cross modulation.

I file the shoulders of the socket to get another millimeter closer to the plane of the board to reduce this interaction to a minimum.

As mentioned above the special socket which is also gold plated is supplied with the auction. Well, that about completes the description for this auction. Enjoy the photo below which will permit you to conceptualize the this process better. Some other points - a fellow ham in Spain has a modification where a different configuration pin out relay is used.

Enjoy the photo below which will permit you to conceptualize the this process better. Some other points - a fellow ham in Spain has a modification where a different configuration pin out relay is used. The modification entails soldering to the bottom of a socket which is then used in the holes for the original relay.

However the traces on the bottom of the board also have to be cut and several patch wires are soldered in place. Unfortunately these wire paths now cross over one another when they should not. This reduces the performance of the front end because of cross modulation and signal leakage.

I have photos of a board where this abomination was performed and a comparison board to show what the final product of that effort looks like in relation to the original design.

If you are interested in those photos check my website at www. By the way if you have ever tried to solder a small wire to the underside of a small plastic socket with lead spacing of 0. See Photo to the left of the PA board, RL01 should drop the PA screen voltage from v to v when the transceiver is switched to the 10 meter band.

The circuit on the final unit can bee see on page 63 of the FT technical supplement in the lower right hand corner see L07, R06, Q01 transistor switch 2Sc which then goes to the coil of RL01, ironically none of the parts listed here will show up on your schematic diagram. How is RL01 switched on and off? In the lower right hand corner of your final unit you will see a contact at L07 Labeled 28 MHz. There is a brown wire on this corner of the board. Yaesu initially placed it there to switch the screen voltage to a lower value when on ten meters for better efficiency.

The relay was inconstant and gave them troubles so they just left it in the radio without switching it on or off. Since they didn't make the radio with RL01 active for regular production they took it out of the schematic so you will not see it although it is most certainly there.

It was easier to erase the parts from the schematic than alter and redesign the boards. So just take the orange and white wire and place it on the other side of the relay so there can be no problems. I'm not sure what the Yaesu engineers had in their heads other then sushi and Sake rice wine on the day they all got together and designed this gem called the FT I removed it from my transceiver and the rig is all the more reliable.

I obtained these after many hours of searching and letter writing.Trade Network has been providing downloaders worldwide a handy sourcing guide for over three years.

After this the arms holding the contacts are bent back with special tools to expose the surfaces of the contacts. Now comes the hard part. I removed it from my transceiver and the rig is all the more reliable.

However if you are brave just solder it in place as I am confident it will be and stay good. We are continuously improving our services to create a reliable trading platform for the online trading community. Two schools of though currently exist for repair or replacement of this relay.

The unit is again dried and the top replaced. This single relay in the FT that stirs up the most controversy among those in the FT community of users is that of RL02 on the RF unit as it is no longer available. Check for availability as we only have a limited supply of original Fujitsu relays in a complete relay kit if you are in need of this part.
