W7RY QSK Input RF Relay and Circuit Board Mounting:
$14.95


The relay INCLUDES a circuit board with the relay mounted on it.as well as space for R19, C11, D1 and R20. (D1 and R20 are installed across the coil of the vacuum relay on all of my designs).
W7RY RF Input QSK RelayThis sale is for a high speed and very quiet 12 volt relay that is designed to work with all of the W7RY QSK products.
The sale is for ONE relay soldered to the circuit board as shown.The relays are quite small but pack a 2 amp contact rating per contact set. Iparallelboth sets of contacts on the circuit board.
These are NEW and fresh relays and not some \"B\" stock or counterfeit item from China. Which is why this has taken a while to find the best relay for the job.
I have tested these with 100 watts and very long key-down at 100 watts, and they have no heating and very low loss and they work perfectly.
The value for R19 (resistor across the coil of this relay) on my QSK products needs to be 220 Ohms 1 Watt.One side note..
I have observed that in ALL of the amplifiers (SB-220, SB-200, TL-922, AL-82, Drake L4B) that I have installed FAST W7RY QSK RELAY systems into, have QUIT arcing in the the tuning capacitors even with no additional parasitic suppression methods! In my opinion, the reason for 99.5% of tuning capacitor arcing is improper T/R relay sequencing and SLOW open frame relays that cant keep up with your modern transceiver.
This is not a kit. It is a bare circuit board with the relay, board layout and limited instructions. If you are not familiar with amplifier construction, design and how they work, you may have difficulty with this board. Please get an \"elmer\" to help you.Because I no longer get your email address fromwhen I get notified of yourpurchase,you must email me at the address shown in thepictures,so I can send your documentation. Please include your ID in your email.
International shipping please note! I ship by US mail. I cannot track an item any better than you can. It takes time for items to get to you. I cant control this time, nor can you. I\'m sorry, but I cant be responsible for the mail system world wide. Please understand this. Thanks!Thanks and 73Jim W7RY
