    Sirio Model 2016, design and function question

    Being that the Sirio 2016 has more yet shorter radials, is there any chance this design is using the braid of the coax as part of the ground plane? If the answer is yes, then would it not be recommended to put a common mode choke at the feed point of the antenna, even though it is mounted to...

    Antenna Experts Needed: Common mode filter issue

    Included photos of filter in question and specifications of said filter. Here is the issue. The issue appears on 2 different antennas, but I will use the Sirio Gainmaster antenna for the example of the issue. Keep in mind I tested the common mode filter into a dummy load and the SWR is 1:1 so...

    With a Ranger radio with a variable low to high power control on radio, when you adjust the high the power control on board ( VR-15 ) if you set the radio variable knob fully clockwise, and adjust the high power control (VR-15) for a lower dead key, does it drop the dead key and AM peak...

    Base Gainmaster stronger than you you think

    Recently installed a Sirio Gainmaster 64 wave. Just got hit with 70-75mph winds and hung in like a champ. Bent far over in the wind but did not snap.I believe and always have that it's assembly error that causes the first to second section breaks. May be 2nd section not inserted deep enough...

    Low pass filter use and linear amplifiers

    I always by habit run a quality low pass filter after amplifiers due to being in an urban environment to be neighbor friendly just in case. With a modern HF radio (not a CB or Import radio) is there any reason to run one prior to the amplifier or is the harmonic suppression sufficient from...

    Do Tubes have a different sound than transistors?

    Don't know why they would but in other amplification of old, tubes had a different audio response then transistors. Maybe it makes no difference in RF amplification

    Ameritron and ALC hookup

    Any reason to use the ALC hookup from amp to a modern day radio if the radio will not be driving at full output of 100 watts, but at reduced wattage?

    Ameritron Pre Purchase Tech Questions

    Which Ameritron would be best suited with 10 meter mod if one is looking to keep PEP at no more than 400 watts SSB use only. Looking at new 811 or 811H new vs AL-80B used. Long.Life and low failure is a concern. Can one get a AL-80B down to 500watts pep on 10m with reduced drive from radio...

    Anyone remember this Antenna?

    Anyone remember this antenna? I searched my memory and remember the advertisement for this antenna but I never knew of even one in use in the 70's. Interesting concept and wonder if Avanti acutely sold many. If there was one today I would buy it just to see if the concept acutely worked. Also...

    I swear I have been through every evolution in DSP and to say its some great feature? I say whatever! I find myself turning it off or setting it at it's lowest level because to me it is as irritating as the noise it is suppose to cure. It's just a different version of irritating noise but now...
