Batteries for Portable and Field Radio

  Batteries for Portable and Field Radio When we go portable or operating in the field with radios, what batteries do we use? Well if it is a handheld radio or the radio comes with its own battery installed chances are that is the battery you will be using in the first instance. If you intend operating for any length of time or are preparing for an emergency situation chances are you will have auxiliary or backup battery or power supply. Myself, when in the field or up in the hills and mountains I currently work exclusively of battery, though I will be adding some solar panels to that mix shortly. But lets concentrate on batteries at this time. New Zealand being the antipodes of just about anywhere suffers a lack of range and choice that our fellow radio operators in USA, Europe and even Australia can often take for granted.

Amateur Radio in Disaster Relief - New Zealand Posted in QRZ.com 24/09/24 As I write this post I am aware that it may get some mixed reactions, but its main intent is to get some ideas and advice on how to tackle a problem I am having here in New Zealand. Just to make things easier going forward let me list some comparative organisations and classes of radio in the NZ and the equivalent in the States.

Playing with Tuners and Longwires   I   am always on the look out for the ‘holy grail’ antenna. I might not ever find it but I gain a lot of experience and have a lot of fun along the way. My latest dive into the quest has taken me down the longwire route with a tuner and a chalk-line winder. First the tuner. I was looking for a small, capable, manual QRP tuner. I finally decided on the Emtech ZM-2 and a no name Chinese Z-Match Tuner that seems to be currently flooding the internet. Morten,  @LB0FI  has done an initial video on this tuner with a promise of more videos to come……I look forward to them TwoTuners - EMTECH ZM-2 and Chinese Z-Match I started off with various random wire lengths and generally settled around the 42 foot mark as with the SOTABeams Band Springer. While the Band Springer worked reasonably well it still was not producing the results I was looking for. And then Fraser,  @MM0EFI  put out a video of an activation that he did using the ori...
