Amateur (Ham) Radio BS and Callsign Thread!

I have this one. The seller can be slow to ship but the J-pole does work well.

Thank you both!

I am not sure how much anttenna gain I need but 2dB-3dB (including RF cable losses) would be great.

 

A typical jpole is going to be about 5dbi of gain, unless you are going about 50 feet with crappy rg58, you should be right about those numbers. As always, buy the best feedline you can afford.

 

Gonna go with 10ft of LMR-400.

 

Amphenol actually makes an SMA connector for LMR400/RG8, part number 132333. The Anytone probably uses the reverse SMA so I assume you're thinking adapter but seeing the big ol' fat LMR400 going into an SMA is almost comical. In real use I wouldn't recommend anyone do this for an HT, it's likely to break the connector. A 6" LMR100/RG174 pigtail with an SMA to whatever is more kinder to the radio.

 

That's awesome.

 

Just passed my tech exam doing a online session with 5 other VE's watching me, lol

Make sure to have an FCC Registration Number (FRN) before setting a date to avoid delays

 

Congratulations!

 

When wiring for a HAM radio in a truck, would it work to wire it off of a Bussman RTMR or would that not properly separate it from the noise of the other devices?

 

Best practice is to run directly from the battery.

 

Hey everyone! So I was planning on taking my HAM test right as everything shut down so needless to say my class was cancelled. I keep hearing rumors and stuff of online testing being a possibility. Was curious of any of you have hear anything about that?

 

From what I can find thus far, it has been completed successfully once.

Might be coming in the future.

I started working towards my general the 1st of the yearish. First test date in my area, May 3rd. Doubt it will happen so I am definitely interested in this option.

 

Little overkill for a ht isn’t it?

10’ of RG8x and a PL-259 To sma adapter should be fine. The adapter will take the strain off of your ht connection.

 

That's about 500% overkill.

I’m not even using LMR-400 in my HF base rig.

 

You're not even using the hf in your base rig.



<3 ya Murph haha

 

Actually I do. Just dealing with a bunch of quiet fuckers.

 

I'm hip to your tune but I'll mention that for a dual band radio that covers UHF it's not completely nuts. At 440MHz RG-8/Belden 9913 will lose about 1/4 dB even at 10 feet, so 5 watts in gets 4.7 watts out. Compared to 10 feet of RG-174, which loses in 10 feet 2 dB. Meaning 5 watts in gets 3.1 watts out. That's just 10 feet, not a typo. At VHF it's not quite as bad. Again 5 watts in, 10 feet at 146 MHz RG-8 is 0.15 dB loss or 4.8 watts (essentially lossless) out and RG-174 loss is about 1 dB or 4 watts out.

It's always a trade-off between cost, ease of use and loss. I ran RG-8 for my house 2m/70cm, which ended up about 60 feet, because it's just not practical or cost effective to run heliax or even semi-rigid coax. But this gives about 1.6 dB of loss, which means 50 watts at the radio only delivers about 34 at the antenna on 70cm.

 

All else aside, isn't that still essentially just 1/3rd of a an S-unit perceived?
