    There is absolutely no reason they can not charge a monthly fee to help maintain equipment or cover tower lease fees. I know Attica repeater coverage is exceptional. In the past I had a group of folks that used my repeater and not official but we all pitched in for the electric and tower space. Its not free everywhere. Our SAR team pays $35.00 a month for electric at a site we use for 2 UHF repeaters and APRS. Money has to come from some place. My repeaters ae closed for this reason. I pay to maintain and put them up. You want free get your ham radio ticket and go use them.

  2. For reference, the power draw of the XS20G’s big brother, the KG-1000G, is as follows: @Idle @5w @20w @50w Conventional wisdom is to choose/design a power system so that the steady/continuous draw of the load is no more than 80% of the power system. For the 20w setting above, this would suggest a 7.5A supply.. However, this theory does not necessarily account for power-up surges which can be high. A 1.5-2x (and more) increase in power supply system capacity can at times be required. This would suggest a supply that can handle surges 9-12A (which would explain the 15A fuse). Most power supplies include some degree of surge capacity, which may be very well be 10% and more of their continuous rating. A well designed 10A continuous rated supply therefore would, in all probability, comfortably hand surges of 11A and greater. So assuming the KG-XS20G falls into the same 6A load draw as its big brother, a 10A + continuous rated supply would seem to be of sufficient size. While smaller sizes may also work well on receive, depending upon the quality of design and internal headroom of the supply and how long your transmission are, you may experience performance gremlins that have you scratching your head when transmitting. In the end, there is nothing wrong with the manufacturer’s 15A recommended power supply. It provides a very good and responsible safety margin. It also provides some extra power available for other things when you need it. Regards. Michael WRHS965 KE8PLM

    Get 'er done...almost there. Everything is in place, initial test successful hit the repeater and making contact. My transmission was readable but noisy. Maybe it was that I was going through the swr meter, which btw was at 2.66. down from 5.89 uncut. I did leave it a tiny bit longer than the suggest cut in the chart, to have something to go by (baseline). Other things I noticed was the knurl section of the antenna end and the smooth inside of the cable (see pictures)...is that going to be an issue? Everything else seems okay but I'm sure I'm missing something. I'm gonna cut the antenna down to specs now and see what changes it gives me. Not gonna to start securing thing too much until a acceptable swr is reached.

  4. VoLTE on FirstNet is unusual. Not to say nonexistent (BeOn), but unusual. FirstNet is primarily a data service. My experience with LTE has been very poor - consumer-grade junk that sacrifices coverage for data speeds and falls down even in populated areas. For essential communications, we use encrypted LMR, and the SWCRS system when longer range is required. WQVS960 has done an outstanding job building that system. I understand the desire to record traffic, but forcing repeater operation without provision for contingencies is negligence no matter what the justification. Radio inhibit commands keep the unit from working at all, not just on the system.

  5. Private company charges for use of its equipment! News at 11! You're not entitled to use somebody else's repeater, and it's quite reasonable to ask for money to offset construction and maintenance expenses. Sites aren't free, you know.

  8. If you have a cable that works for the GM-30, it should also work for the KG-935G as long as it has the same kind of connector, which I believe it does (My KG-UV9G does). You shouldn't need a separate cable.

    Here a link to the spec sheet for standard LMR400 https://timesmicrowave.com/DataSheets/CableProducts/LMR-400.pdf. Bend radius specifications are included within. They give two ratings. A once and done installation rating and another where repeated flex will occur. Yes, you can using a different cable for jumper, but is should be a 50-ohm jumper. Use the shortest practical length that suits your application. Do not deform your cable. Do not kink it. Do not secure it so tight that shape of the cable changes. Take and record reference measurements of your antenna system (feed-line, adapters, antenna) before permanently installing anything. Make sure all is acceptable first. If all is good, then install. Take SWR measurements along the journey so you can immediately spot any issues you have caused (such as kinking or deforming cable, effect of adapters, etc…). Yes, in most cases you can leave an SWR meter in circuit. Mine remains in circuit full time. I power it up when I need or want view readings, otherwise it remains off. It continues to pass signal when no power is applied. Michael WRHS965 KE8PLM

  11. Turn to 144.39MHz and see if you would ever be able to get a word in. Now think you had out a handful of radios to family members and just let them go.
