DIY QRP 4 PACK FOR 40M CW (FT-243 STYLE HOLDERS)

Description

YOU ARE PURCHASING A 4-PACK OF FT-243 HOLDERS AND 4 HC-49/S CRYSTALS. THIS IS A DO IT YOURSELF, SO YOU'LL NEED TO HEAT UP YOUR SOLDERING IRON AND INSTALL THE CRYSTALS, PRINTING AND ATTACHING FREQUENCY LABELS, IF DESIRED.
THE PHOTOS ARE GENERIC, BUT YOU WILL RECEIVE 4 OF THE FT-243 HOLDERS, ALONG WITH THE HC49/S CRYSTALS TO INSTALL. THERE ARE SEVERAL VERSIONS OF THE FT-243 HOLDERS, BUT ALL HAVE THE SAME PIN SIZE AND SPACING.
YOU MAY RECEIVE ANY OF THE DIFFERENT FT-243 STYLE HOLDERS, OR A MIX OF SEVERAL STYLES. NOT NECESSARILY ALL OF THEM WILL BE AS THOSE SHOWN IN THE FIRST PHOTO (PLEASE SEE ALL PHOTOS).
I HAVE THE FOLLOWING FREQUENCIES AVAILABLE, ANY OF WHICH MAY BE REQUESTED IN LIEU OF THOSE LISTED ABOVE: 3535, 3550, 3560, 3579, 7023, 7030, 7035, 7040, 7045, 7048, 7050, 7055, 7060, 7110, 7114, and 7122 KHZ. 10.106, 10.111, 10.116, 14.048, 14.050, 14.060, 18.096, 21.050 AND 21.060 MHZ.
DURING PAYMENT AND CHECKOUT PLEASE LET ME KNOW IF YOU PREFER ANY OF THESE ALTERNATE FREQUENCIES. OTHERWISE YOU WILL RECEIVE THE 40 METER CRYSTAL FREQUENCIES, AS SHOWN. AGAIN, YOU WILL BE INSTALLING THE CRYSTALS YOURSELF.
I HAVE USED THESE LITTLE CRYSTALS WITH GOOD SUCCESS IN LOW POWER QRP RIGS AND HAVE SOLD HUNDREDS OF THEM TO OTHER HAMS WHO HAVE HAD SIMILAR RESULTS. BUT PLEASE USE THESE ONLY FOR TRANSISTOR OR VERY LOW POWER VACUUM TUBE CIRCUITS.
IF USED IN ONE OF THOSE SINGLE TUBE TRANSMITTERS, LIKE THE 6V6, 6L6, 6DQ6, ETC., YOU'LL LIKELY ENCOUNTER CHIRP AND INSTABILITY PROBLEMS. FOR HIGHER POWER APPLICATIONS YOU'LL NEED THE HC49/U TALL VERSION OF THIS SAME CRYSTAL (PLEASE SEE MY OTHER LISTINGS).
SHIPPING TO THE UNITED STATES ONLY.
