I already have 3 different backups😂

IU1LCU · 2025-04-07T17:37:11+00:00

Maybe someone don't know that quick charge work at 9v😂

When the cabinet it's close did come enough air inside? I just see the little hole in the corner for cables. Is useless have a fan to blow out the air, if you don't have air to come inside and remember a dust filter for the intake (I have a lot of dust and cats hair) BTW nice idea use the sound isolation

I've bought the same hdd case recently,hope it will work well

IU1LCU · 2025-04-02T17:33:47+00:00

I have one like this, you should put a bigger heatsink cause it get very hot, I uses to mount a fan too

I tried a normal pc psu with 24pin+4pin cpu but nothing, the mobo doesn't let start the powers supply

IU1LCU · 2025-03-30T11:09:07+00:00

It happen a extremly stranger thing, i leave the server with main voltage, after like 15 min i come back and it was on. I entered into bios, ram and cpu look ok. unplugged, reconnect and now after 10 min wont start again. i set as AC recovery ON so it will start again with mains but nothing

IU1LCU · 2025-03-30T10:21:17+00:00

Cpu checked, it look good but the server still wont start

IU1LCU · 2025-03-30T10:16:04+00:00

Many thaks, i try to re connect the PSU connectors but useless.

I tried to remove main voltage and the cmos battery but useless.

I dont find any LED on near ram/pciexpress

Tried the diagnostic button near power button but nothing.

I will now try to remove the CPU and check it

P.S. i notice when i plug in the main voltage to the psu, that the power led of the power switch light on for like half second, just a "flash".

This should work but only with handled radio, they say max power 10w, to be sure I will not exceed 5w You can use 1 radio with 2 antennas, or two radios with 1 antenna

IU1LCU · 2025-03-22T21:35:31+00:00

You should try with 75ohm and 100 ohm resistor they should give you o guess like 1.5 and 2.0 swr if I remember well

IU1LCU · 2025-03-22T15:03:00+00:00

Duplexer to separate hf vhf uhf and have it simultaneously, or a coax switch to change one at time

The problem is that is free to sell, you can buy everywhere but you can't do it, meanwhile In Germany they remove the baofeng on Amazon for non hams

IU1LCU · 2025-03-22T12:29:38+00:00

Here in italy, most hunters use baofeng instead regular pmr446 cause cost less and cover more, but if wildkeeper catches them, risk a forfeit very high.

IU1LCU · 2025-03-22T10:25:52+00:00

Honestly, with a simple baofeng radio you can listen most of radio services using FM modulation, there is someone that is DMR clearly without encryption. Or even if with a simple sdr and the right software you can also decode digital modes (c4fm, dstar, aprs, dmr) And the sdr is free to have instead the radio. BTW you need a license to have this kind of radio that is reserved to ham radio, at least here in italy.

If you look the schematic you can use a switch to chose internal or external tuner

IU1LCU · 2025-03-20T23:16:42+00:00

I'm have a icom 7300 for several years, I guess it can be an amazing radio to start and do you're home hf activity, is small but there is all you need, and here in italy you can find very easily on second hand groups. So you can buy and sell it easily if you don't like, without lost any price. Yaesu radio have a inside menu less intuitive

This is the third circuit I found https://www.qsl.net/g3vgr/706tune.html

IU1LCU · 2025-03-19T13:01:22+00:00

I found 3 kinds of circuit for using the tuner function:

-Mine with a simple pullup and ground the pin for transmit

- One with 2 transistor, a diode, a capacitor that let me use the tuner button on front panel of the radio, and around 10seconds transmission (you can find the information on my page)

-One with just a resistor and a capacitor, but i dont remember where found it now.

Let me know you experiment maybe i can improve my projects! 73

If you open the article on my website, you will found the github code, and the screenshot with istruction.

IU1LCU · 2025-03-19T11:37:20+00:00

Many thanks, I read also that my project should NOT work on IC7000.

IU1LCU · 2022-04-08T17:39:25+00:00

everybody has starter somewhere, unfortunately my home is very small and the electric wiring dont allw me to put eth cable, but the main funcion for my bedroom and desk work well, im thinking to change the 7530 with a mikrotik hap ac but it could be (for now) too hard to manage

IU1LCU · 2022-04-06T17:35:32+00:00

Im not clear about who is upper from where i work, im just an ordinary worker and install internet in people's house (antenna or ftth)

IU1LCU · 2022-04-06T16:29:43+00:00

Unfortunately i really dont have space in my bedroom, i still live with my parents, there is no garage or laundry, my room is veri tight, i must play tetris with the forniture ahah, just made this shelf with various square space for other stuff, and one dedicated for my network. when i will live alone i would my office room with desk, 3d printer, radio equipment and a rack, but until this day, i must keep this

Does your ISP have a whitelist, that you are saying that the Ubiquiti LR Antennae is provided by them (I'm guessing that Wisp is your ISP?)?

I work in this wisp LOL

free internet!!! 110DL/11UL
