Why Do You Need A 3898 Pecker?
The Pecker is used to tune your amplifier (& tube final transmitters) in the SSB Mode without a CW or AM RF carrier. The Pecker is a single pulsed tone that works with a 70% off & 30% on duty cycle with your transmitter in the SSB Mode. This short duty cycle allows you to take your time on tune-ups (or testing of your amplifier, antenna, or other equipment), with very little chance of tube damage, power supply stress, and arc-over with your amplifier, or tube transmitter, like you have using a CW carrier. The Pecker allows you to tune your amplifier to full Peak Output Power quick and easy. You will never go back to the old "Peak & Dip" tune-ups with a CW carrier for drive once you have used a "3898 Pecker". Ask those who use a Pecker and they'll tell you that for speed and ease of tune-ups, you just can't beat the Pecker. (For more information on why the 3898 Pecker is the best choice for SSB tune-up, read the article in the News Gallery.) HF Operators of all ages and in 25 different countries have bought the 3898 Pecker. Read some of the reviews they posted at http://www.eham.net/reviews/detail/5121 .
I have made hundreds of these fantastic tuners over the years, and now here is your chance to get a 3898 Pecker, board, or a custom built "In-line Model" for your radio station. Don't be mislead by MFJ's "Amplifier Saver Tuning Pulser" (the MFJ-214). That device just plugs into the transmitters CW key jack and all it does is pulse your CW carrier while the transmitter & amplifier is still in the CW mode. (You'll get the same results from a CW speed keyer.) The 3898 Pecker uses a single pulsed tone through the radio's SSB MIC audio circuit , thus tuning your amplifier in SSB MODE for SSB OPERATION.You must use a PEP meter when using the 3898 Pecker because the short duty cycle won't let the average reading meters show the full out-put of the amplifier. Thus making it harder to see when the RF hits it's peak out-put.
The 3898 Pecker can be used on any SSB transmitter that has a ALC control. I have built them for Kenwood, Icom, Yaesu, JST, Collins, Drake, Heath Kit,Ten Tec, Swan, Flex 5000. If you have some thing other then those I have listed, contact me before you order.
