Start of the 2017 Atlantic Hurricane Season

June 1st marks the start of the 2017 Atlantic Hurricane Season. NWS Taunton has sent out a Public Information Statement regarding the start of the season including storm names, some Southern New England Hurricane History and tropical system safety tips. The National Hurricane Center has now started issuing their Atlantic Tropical Weather Outlooks and have provided info on storm names and their various products. Details at the following links:

NWS Taunton Public Information Statement – Start of the 2017 Atlantic Hurricane Season:

National Hurricane Center – Start of the 2017 Atlantic Hurricane Season – Tropical Weather Outlook and Overview of Products:
http://www.wx1box.org/local/two_atl_nhc_hurricane_season_start_2017.txt

It never hurts to have preparations in place and review safety rules prior to any impending tropical system affecting the region. This info can help you stay informed and understand products issued by the National Hurricane Center and National Weather Service in Taunton and prepare properly if Southern New England were to be affected by a tropical system this season.

Tech Talk – A One Transistor Marvel Transceiver

[UPDATE] At the June 1st Business Meeting, Joe Tavares, KC1BGF, will give a Tech Talk on the “One Transistor Marvel” transceiver. It is a Dave Ingram K4TWJ design that Joe found in a QRP builders book.

The circuit is a one transistor crystal-controlled CW transceiver. The oscillator puts out about 200 mW in the 40-meter band. On receive, a hi-Z crystal earphone across the emitter resistor picks up signals that beats with the oscillator.

This is basically a crystal set with a BFO.

When the code key is pressed, it becomes a transmitter and transmits on 40-meters.

It can be connected to a full size 40 meter antenna. A one or two foot length of wire will work just fine for experimenting.

Shown in the upper right is a pi network you can add to the transceiver.  Its function is to filter out unwanted frequencies.  IJoewill eventually add one to his unit but it will work without it.  Joe needs to find the right toroid to wind the coil for 40 meters.  Joe’s unit is built into an Altoids case.

Joe found that when he connected the earphone, the transmitter won’t work.  He then decoupled the earphone with a 10 uH coil in series with the earphone; and the transmitter started working again.  He figured it would have a high reactance to RF; but it does allow audio to the earphone.  That is the only change he made to the circuit.  Joe hopes his addition doesn’t cause the oscillator to chirp.

These are the values for the pi network:

40 m   470pf    16t  #28 wire on T-50-2 toroid
30 m   330pf    13t  #28
20 m  .220pf    12t  #28
