    No they don't! vehicle mounted radios have a bit more power, but the key to the greater range is the antenna. A 5W handheld only gets a tiny bit less range than a 15W mobile - on the same antenna!...

    The dual meter ham designs for 2m with the variable sensitivity knob will work well for aircraft band - and will give full scale forward readings on quite low power. They're not expensive either.

    I'm a bit mystified by what people really expect. Radiosification stuck up a new video on youtube about this subject today.

    I asked the guy who collected the medical oxygen cylinders here today, and he had no idea. He had no training on any specific issues with oxygen. These things are also very low flow devices too,...

    Looking back - it's also clear territory has a huge impact on words in common use, as does age, gender and socio-economic grouping (UK readers call this one 'class').

    Let's be honest, anyone who really believe the old magmount on a biscuit tin approach has NEVER tried a decent antenna. There is a huge difference between a good antenna system and one that a VSWR...

    I remember when here in the UK we were experimenting with ATV in the 80s - in the 10 meg wide UHF band. Back then our Government were really on the ball with band monitoring and control, and visits...

    I meant what are you up to, as in are you switching multiple antennas or multiple radios, and it's just antennas.

    I'm actually a bit surprised that you are getting bleed-over? If you have a poor...

    The trouble is, if you cut it open, that I bet they have swapped the pairs around - so while all the circuits are connected, they're not sharing the twisted pairs. Only takes one person at the...

    How are you using it - to switch multiple antennas to one receiver/transmitter, or more than one receiver/transmitter to a single antenna?

    It's important because most are designed to switch low...

    I rather liked the bit about your wife hearing you - getting me out of the house to a place she CAN'T hear me seems her quest - the idea of giving her a radio to hear me would mean divorce here!

    Why not just attach a long random length piece of wire - and string it up down the garden. Connect to the radio and go through all the bands - remembering t whack up the RF and AF gain - a long wire...

    You need to befriend the local hams really, because you need people to put aerials up, climb up ladders, drill holes and get your station set up - and I bet they'd be more than happy to take you to...

    The important thing to remember with repeaters is that THEY do the work, you transmit with your available power, the repeater then retransmits it - it is doing the work.

    Tend to agree - first thing is to replace the amp with the VSWR meter and check it's good, then try the amp into a 50Ohm dummy load and see if power output maintains.
