It was RF problem, not with mmdvm. We swapped the antenna with a 9m2rkl during a test and the 9m2rkl becomes deaf too and the experimental repeater was okay. Until we get someone to put a new antenna and cabling, the repeater is taken off-air.

I hope there will be a DMR repeater up and running soon, the availability of cheaper China made DMR radios really incite the excitement all over the world. But to compare the cost, Yaesu has brought up 3 budget minded radios which support the wiresx and c4fm. The three models, one dualband handy and two single band mobile rigs cost around RM700 each, still within most budget non China made radios.

The ft70dr is much better than the bug ridden tyt md2017

Ah I see. Good to hear that the problem was identified

Yeah the TYT is not exactly the best around. I really hate their trackball system. No idea why would you put a trackball into a utility radio.
Just that DMR is a pain to program since it was not exactly designed for HAM use.

How do you earth vhf antenna on 2nd floor concrete house.is an omnidirwxtional antenna

You could try tapping into the electrical's earth. Those go into ground.
Otherwise, you could try doing something like a ground tail/rat tail.

Anyway, I've setup my static hotspot in Cyberjaya. Hoping to get a wire to extend out the antenna to give better coverage.

Hotspot details:
https://brandmeister.network/?page=hotspot&id=5026001

Freq: 433.550MHz
Color Code: 1
Static TG: 5021

Wait, why you need to earth your antenna?

Nice! This covers berapa radius in Cyberjaya?

Have not done any coverage test yet since the Echo test(9990) is kinda down today and I have not setup the outdoor antenna yet.
I just got it setup this weekend but I am expecting it to cover MMU area hopefully.

Will update on this but as of now, it is open for use if reachable and has the static talkgroup set to 5021 but will allow dynamic talkgroup. Usually I'll put TG91 on if I wanted to make it constantly transmitting.

I thought u need it for diverting lighting current flow to earth?

You don't ground the antenna, you may want to ground the antenna mast but, lightning loves the fastest way to reach the ground and your mast probably will attract lightning more than before Get a lightning arrester if you want to protect your equipment. I grounded my mast and I've arrester inline with my feed line. The best protection is always disconnect your equipment when you're not using it. I've a gateway radio running 24x7, and I had hit by lightning before, not direct hit though on my radio but my HF set went kaput along with my TV, and astro decoder. My VHF set seems to be working fine till now, probably the static went into my HF set through power line instead of antenna feed line.

Sorry i was referring the mast.Anyway any suggestion how to install the lighting arrester and ground the mast?It is on 2nd floor concrete house middle lot.No access to soft ground.

Expensive way is to buy those copper strip, the one you can usually see at taller building where they installed the lightning rod at the roof top. Surely this is expensive, so, I'm using the normal green cable that you can find from any electrical shop to do my grounding. I've another grounding separated from house ground, 12' down (2x6' rods). I just run the cable from the mast to this new ground point.

No soft ground? Just don't ground your mast I don't think its a good idea to have it connected to your house electrical ground.

Lightning arrester? Just buy the Diamond SP1000 lightning arrester, but, still you need to have a good ground. So, by hook or by crook, if you want a safer installation, you need to have a separate grounding system.

Mayb instead of using base antenna i use mobile antenna?

Hardcore contester with lot of money! Hehehe, most contesters will unplug their radio during bad weather.

Not yet up,havent bought anything yet.Just getting info 1st,planning to get very soon once info enough.

Planning to play with VHF 1st.If interest grows,maybe upgrade to HF.Am planning to have VHF antenna higher than roof.

For the Love of Amateur Radio. BUMP!~

Looking for someone to QSO this weekend. Haha

Was wondering any different btw a base and a mobile antenna?
