Hello,

I am not sure if this section is where I should post this?

I recently picked up a BC1G.  It does not have the K2 Contactor installed.  This is used for the high output side. (1000 watts)

From what I have read, it seems to be generated by 220 volts.  

I have been in an email conversation with someone who is trying to help me out and he thinks he may have one, but he is not 100% positive.  

Can someone give me some insight on this contactor?  Any information may help?  

Does anyone know if the K2 High Side Contactor is the same as the Main Contactor just left of the K2 Contactor?
I don't have a clue here, but I would think that K2 would be the same as K3 which is the Low Side, but again I have no clue.

Thank you,
Ken

Why would there be a different contactor then the others?
A contactor is a contactor, coil voltage and contact ratings are the only things that change, and the coil would be the same....

I have a good original for sale if you are interested.

Big honkin' relays that operate at 230 volts.  It controls the primary voltage of the HV plate transformer in the BC-1T and the contacts are also 230 Volts.  I assume the same is true for the G.  I have a full set from a BC-1T.

Heating and air conditioning units use the same things, I have/had some from my days as a heating/ac tech.
For fans, compressors, electric heat.

The contactor was replaced by the contractor,
who spoke in hushes of little black brushes,
and warned of the odors of motors with rotors.

Opcom, you're a poet but the world don't know it. Your feet show it, they're Longfellows.  ::)

Arrgh.

Go to local electric supply house.

Pick up 50 amp contactor,  with 220 coil.

Install

Transmit

Be happy.

Grainger carries them,  as do graybar.   If you have C. E. D.  Consolidated Electrical Distributors,  GreenTech,  they are usually slightly cheaper.   Sometimes more than slightly.

Would you like me to take a picture of the relay in mine? The Gates part number is 570-0613-000. If you want I will take the cover off mine and give you the specs off the relay.
    I am still looking  for the small roller inductor L42 for my transmitter.

Good luck John N8QPC

Hello,

I just want to say thank you to all of those who replied.

Now waiting for the contactor to arrive!

Thank you again.

All the Best,

Ken

Thank you very much John.

I should be good from here on in.  Now I sit and wait until it arrives!

If I can return the favor somehow, be sure to let me know.

Again Thank you,

Ken

Thank you Shane,

This is my first BC Transmitter.  If I had the original and it didn't work, I could take it along to a C.E.D. to compare, but since it is totally missing from the circuit, I would rather have the original. 

A couple of good Guys here were willing to help me out, so I should be okay now.

Thanks for sharing, I didn't even give the C.E.D. a thought?

Can't help.The BC-1T didn't have a part number that corresponds.

Hello Michael,

Thank you just the same.  As I mentioned above a couple Good Guys here were willing to help me out.
Dennis W7TFO, was one of them!

So I have a K3 Contactor on its way.

If any chance I can be of any help to you, let me know.

Thank you again Michael,

Ken

No problem!  Funny you mentioned Dennis.  I just got through unpacking a big honkin' transformer from him not more than 1/2 hour ago.

Hello Michael,

Well actually the contactor that was on its way has arrived. 

However it was not Dennis' contactor, it was Bruce's Contactor, W2XR. 

Bruce had messaged me telling me he had all three Contactors.  We agreed on a price, payment was sent via PayPal.  The Contactors went out I think Saturday and I received them on Monday which was yesterday!

My postman beeped his mail truck's horn letting me know he was outside.  There he had a box of Contactors in hand.  I have to admit, I was totally surprised to received them so soon. 

I was pleased with what I received. 

Interested thing I found while observing the contactors, they are designed to be mounted on their sides as one would see them installed in the BC1G.

I say this because when I placed them on a table with the mounting plate facing down, the solenoid or the spring tension appeared weak as if they didn't want to fall back to the normal open position.  Then I simulated them as if they were installed on their sides, and instantly they sprung into action as expected.  So I would say they are mechanically weighted so when properly installed they help aid the solenoid and the tension springs.

Again Michael thanks for your help.
