    You can connect two of them with the Intercom cable, select "Auto-Rebroadcast" on both radios and you have setted up an automatic repeater that can work completely unattended as long as they have some power in the batteries or a power supply pluged in.
    And the two stations of the repeater can be placed everywhere between 50m (15 with the Selectivity Unity installed) and up to 3000m away from each other!
    E.g. On the two sides of a mountain.

    UK PRC 351. Frequency range 30 - 75.975 MHz. 1840 channels at 25 KHz spacing. Basic planning range of 8KM, 16KM if fitted with a 20 watt amp.

    One of the advantages to owning military transceivers are that they are gapless. Granted, in a normal situation, you can only use the Amateur Radio frequencies. In a total breakdown, you have a wider range to use with the PRC-351. Let’s hope it never comes to this =) 73!

    Gil, I'm pretty sure you can use that whip without the SURF. If I'm not mistaken its mainly used to combat interference with and from close by radios. Do you have the manual?

    • @gilgsn
      @gilgsn 7 років тому

      VK6OP Absolutely, but I wanted a bit more oomph... Better efficiency with a near-half-wave longer whip and tuner...

    Gil what do you use to charge your PRC-351 24v NiCd battery? I have seen a couple of different solutions & would appreciate your opinion.

      That's great. Many thanks it will get me started. Fortunately my local club runs a 6m net once a week so I am hoping to experiment with a PRC-350. As I have only just got my licence I am cautious about plunging into power supplies just yet until I have gained a bit of experience & know what I am doing but am interested in building a charger that monitors the temperature using the diode output & cuts off if the readings start to diverge too much. I love watching your videos. Chris M6NZX

      SURF unit to measure Radio waves going though the unit.

      The SURF is a band-pass filter.

    Piękne radio, ciężkie, delikatne - obudowa z słabego materiału jakim jest duraluminium - nie wytrzymuje upadku z 1 metra jak nowoczesne radia i wiele metrów (smartphone) , ale to tak samo jak inne radiostacje podobnej wielkości - ciężkie i nieodporne na upadek.
    Działa super :-). bardzo dobry akumulator, dużo godzin pracy w TX.
    Słabej jakości słuchawka - bardzo delikatna.
    Ja następny
    10 km zasięgu w płaskim terenie miedzy dwoma takimi samymi radiami z dłuższymi antenami bez SURF, z dala od miasta.
    Pozdrawiam serdecznie :-)

    Regarding your disclaimer, when you have to explain yourself in that manner, you're explaining yourself to Nazi's. I'm a prepper and a vet, that doesn't make me a terrorist, regardless what the media says.

      Ok, I will let this through, once. Anthony, do you have military antennas? Send me the list and prices to gil@radiopreppers.com, thanks.
