There are not that many ham radio operators in Malaysia, so mostly depa akan jual to friends if they're not using theirs. Best in to ask in that RAFS group if anyone want to let go theirs.

Ok, here is my only 'rig' to practice my Amateur Radio hobby.

1) Baofeng A52, Dual band tranceiver VHF/UHF
2) Modified headset PTT, to be used with my IEMs/earphones collections
3) Homebrew 1/4 wave antenna using ASTRO 75ohm coax wire. SWR 2.4:1 on VHF and UHF bands.
4) The antnna connected to F connect to femal SMA adapter.

Most of the time, TX on 1W to repeaters, 9M2RKL, 9M4RBC, 9M4RZS, 9M4RGH, with R4-R5, from my saltmine (Bandar Sri Damansara) or base (Kajang).



Thank you.

Guys I might need your help here.

I just bought a set of Baofeng UV-5R.
I returned one unit to the seller because a button is defective. I received a replacement unit back this morning.

The problem is that the new unit can't receive from the PRADAS repeater. Wondering if this is a defect?

I've swapped the antenna still the same thing.
The squelch is down to 1, there is no R-DCS or R-CTS set.

I can't figure it out. Really hate to have to send this back to the seller again

@aminpro
1) How about other frequency/repeaters?
2) Make a video showing the units side by side receiveing the same frequency.
3) Most probably, the RX module is goind bad. or, the connector's pin is not contact to the anttena correctly.
4) Or, it might be glitch in the setiing's image. If tou have the data cable, you can refresh/reload the 'clean' image to the unit. I already enccountered with this problem, after tweeking too many things in the settings. Reload the fresh/clean settings, and the problem settled.

PRADAS. Yeah, nice channel if you want to learn how to talk/QSO. If you can access 9M4RBC, especailly during very late night "0000-0300), if you lucky, you might hear this 2,3 person QSOs, talking about technologies and other usefuk knowledge. 9W2ASF, 9W2USA, 9W2SBD. There also some 9W and 9M talking about knowledge, but on 2m/70cm, but, not that easy.

I was told, there was a golden era in Amateur Radio ini Malaysia, where the knowledge of technology is being conveyed via the radio on 2m band, the silent key 9M2GL. Now most them 'run away' to HF, and leave 'what we ussualy heard' in 2m band. For those to have AA and knowledge even a small things, let's share among us. I met/eyeball with a very good 9M otai's, and there are lots of thing to be learnt, beside pushing the PTT.

Here is the close up of the antenna connector and adapter.


I use 2 metal washer to distribute the stress equally to the transceiver's body.

Thank you.

Thanks for the advise. I've tried point to point and it works. Only that it won't capture the repeater's Rx. At first I thought it was a frequency glitch but since point to point works, that is not the case.
Suddenly the radio died. I tried shaking it a bit and there is something rattling inside.

Called the seller and sending it back the 2nd time to him. He also headache, I lagi headache.

I've been tuning to PRADAS because that is the only UHF I can capture from my house.

P/s: The programming cable is too damn expensive for me.

@aminpro

Rattling sound... .. Wow, that's new to me. sure something is broken inside the unit.

PRADAS is on VHF 142.800 MHz. not UHF, or I missed something?
Here are the most frequently used repeaters.

(RX only) in MHz
9M4RBC 147.750
9M4RZS 147.650
9M2RKL 439.600 (UHF)

These repeaters are active during rush hours, or during weekly 'check net'.

Programming cable is expensive? I bought it with my radio set, about MYR 24. You can get less if you shopping around on the net.

Thank you.

I've been in your situation before .. met this one 9M2 guy who always talk about the golden days, how he run/setup the station for field days during his SWL time and the 9M2 just watching them etc. Nice to hear the oldies for sure but we're in the modern age now. Do mix with the younger ones too and enjoy the hobby. Enough with the dulu-dulu cerita, if you've time, follow any field days, DX, programmes that are related to amateur radio. Most of the otais now are very selective in what they want to involve at. Piju should know who I was talking about. Hehe.

I believe in 20 years time, I'll be in the same shoes as the 9M otai tu .. cerita my 21 centry golden era

hello world, newbie here!

@wiraone
2m band also the Amateur Radio band. 9M/9W otai-otai also need to visit 2m band, time to time. Share your knowledge, lets the newbies like me, learn something beneficial.

Here is the clip from MHI episode 187, 23rd September 2014, covering National Field Day 2014, at Taman Tasik Cempaka, Bandar Baru Bangi.

I downloaded the clip from tonton.com.my.





Enjoy.

73,

I believe the timing when people go on air tak kena kot, we had 9M4RES before which was quite active, 9M2AU and some others were frequently on that repeater, talking about some technical stuff. But the timing usually after everyone were in the office already. The repeater is dead now. Some other repeaters were full of people rag-chewing during the peak time when they're driving from-to home/office. For me, the only time I'm active on VHF/UHF will be when I'm driving around and when I'm driving alone. For me, family time comes first, so, if my wife or kids are with me, I don't usually go on air. The same when I'm at home too. I believe that is the same to most of us .. and that is why there is no activities during office hours or after office hours on the repeaters or other simplex frequencies. That is why I do join any field-days, DXs or talks from time to time to enhance my knowledge in amateur radio. This is the time where we mostly share the knowledge as you've experienced it on your first field day that you attended before.

Hello ruth .. welcome to the world of amateur radio.

Sorry I always mix up between Ultra and Very. lol

Btw, where did you buy the cable? So far I can only find at RM 50 online.

@wiraone
Yes, you are right. The TIMING. Yes, when we are around with family, the family is more important than our hobby. Yeah, the TIMING, Since th 2m band is 'alive' during rush hour, so lets start the conversation with the more beneficial topics. Yes, we cannot assume everybody able to talk about technical, but, still efforts are needed to 'enhanced' and share our knowledge. Yes, 9M2AU told me, that during the golden era, he always QSOs with 9M2GL for years, on 9M2RUK repater, while commuting in his jalopy/car.

Nowdays, I frequently hears some good QSOs on 9M4RBC and 9M4RZS, especially durng late night. But, how many people are monitoring that time?

@aminpro
Aliexpress

I just bought the SDR dongle from NooElec. Managed to get it running. However, the antenna connector is MCX rather than BNC which is what normally we have.

Anybody been to Pasar Road to get the MCX to BNC converter?

73

What I did, I cut the antenna cable that comes with the dongle, and replace the other end with an UHF connector so I could easily connect it to my broadband antenna (using RG58 cable).

Thanks Wiraone. You just gave me an idea. javascript:emoticon(':clap:') However, I will make a visit to Jalan Pasar and check out first. I have checked my local electronic stores but none of them carry the converter. The comment was .. wah.. so small arrr.

Good luck, if you able to find a suitable adpater for MCX connector at Jalan Pasar.

I have 2 RTL-SDR dongle, and use SMA-M to MCX-F straight adapter. Since I only have Boafeng walkie talkie, my main connecter is SMA, and I have several adapters to use with other type of connectors, such as, F connect (ASTRO cable), UHF (SO239/PL259) and N connector (SL16), RP-SMA,...

Yes, as wirwaone advice, cut the stock antenna cable and solder it to your own choice of connector.



cox cable anteena -> -F connect-SMA-F-> SMA-M-MCX-F-> SDR dongle

stock antenna lousy ker? just ordered one but cikai one with r208t tuner e4000 mahal

Can't do much with the stock antenna Especially when you're in Sg Buloh, even the reception inside my car pun macam **** .. haha.. but if you're in a very good reception area, okaylah. I bought a discone antenna with a wide band receiving frequency, from VHF up to 1900MHz.

owh...need to invest in antenna then.baru nak setup Rx igate sdr+raspi but when i research yg cheap one got thermal-drift hok aloh xjadi ler.thx 4 info wiraone
