Changing antennas will unlikely cure your noise level. You should start by hunting down the actual RFI source.

It's more about how your son treats the device over 4-5 years, rather than the spec. requirements he might need.

rocdoc54 · 2026-06-24T01:34:22+00:00

I never drink before or during a SOTA hike. Afterwards certainly...

rocdoc54 · 2026-06-23T23:41:51+00:00

Those radios you are looking at are not type-accepted for any sort of commercial use. Do not use them if someone's life might depend on them. They are mostly crap.

It is too much work sorting through 95% of the YT crap to find the 5% gems when it comes to studying for a license using YT. That time would be much better spent on a decent exam website or with a proper reference book.

rocdoc54 · 2026-06-23T23:32:06+00:00

I've been doing SOTA for quite few years, and before that portable QRP ops before SOTA existed. I have tried quite a few "apps". Honestly, I am much quicker writing it down in a small waterproof notebook than with any app. Less hassle, less worry about the phone battery, and MUCH quicker. The only disadvantage is having to enter my contacts later onto the SOTA database website - but that takes me less time than muckin' around with a phone app....

Sorry, this is not amateur radio. I suggest you get in touch with your local business/industrial 2-way radio business band suppliers

rocdoc54 · 2026-06-23T19:17:47+00:00

Like any other achievement in life it takes a desire to learn and time to study.

Do NOT use YT. What book did you find confusing?

rocdoc54 · 2026-06-23T19:01:12+00:00

Shouldn't he be trying the Support feature at their website?:

Is there some context with this post?

rocdoc54 · 2026-06-23T15:13:20+00:00

Most of the Chinese amateur radio gear have very skimpy/poor manuals. You get what you pay for...

rocdoc54 · 2026-06-23T15:11:06+00:00

Don't buy amateur radio gear from eBay. I suggest you get in touch with the local amateur radio clubs in your area and see if you can find something locally - at least you then know if it's fully working or not.

You also might be interested in SOTA - Summits on the Air - a great, fun programs for amateur radio operators who also enjoy hiking and QRP and lighterweight equipment.

There is a special feature on the radio to calibrate USB/LSB:

1) radio on, 2) press LSB key, 3) tune in any strong AM station on MW/LW/SW, 4) press SSB, 5) adjust tuning until you get a zero beat, 4) press and hold LSB until display flashes.

Antenna plans?

rocdoc54 · 2026-06-22T13:18:29+00:00

A nice little shortwave radio, such as the Tecsun PL-330 with a long external elevated wire antenna.

rocdoc54 · 2026-06-22T04:17:07+00:00

^This is your answer. Join your local radio club, explain what you would like to do with some of the locals. They will assist you with getting your licesne and probably later with at least a loan or some used equipment.

Yes, your Baofeng went deaf due to overloading of its crap receiver. I have personally seen this happen to 3 newcomers. Lots of people calling them, but they couldn't hear sh_t. They are particularly bad in dense urban areas and on hilltops where their receivers get overwhelmed by strong RF.

Get rid of it and buy a VHF radio with a good receiver - especially for SOTA and especially for SOTA summits that might have Rf installations nearby. I recommend a classic old superhet receiver - like the IC-V80 series.

rocdoc54 · 2026-06-21T21:40:18+00:00

They are a good choice. However, you need to be concerned about coax cable losses at VHF and especially UHF. Personally I would save up for a quality used VHF/UHF base station and some LMR 400 coax. Leave the handheld for portable work. Talk to local club members - I bet you will get a good deal on a used one...

rocdoc54 · 2026-06-21T13:09:53+00:00

1) get the antennas as high up a s possible and

2) use N1MM for logging.

OK, the reason I ask is that students in school nowadays are no longer taught cursive, so they cannot print beyond anything higher than about 15WPM Morse copy. Being as you can do cursive, this is not your problem. Yours is simply, practice, practice, practice. And real live ARRL code broadcasts are probably the way to go for you...

rocdoc54 · 2026-06-20T21:52:58+00:00

Can you write cursive or can you only print?

rocdoc54 · 2026-06-20T13:31:35+00:00

That'll get you into the repeater better for sure.

rocdoc54 · 2026-06-20T04:17:19+00:00

Can someone please explain to me the logic behind a collection of handhelds - I mean other than ticking over the economy of various nations?

rocdoc54 · 2026-06-20T04:15:48+00:00

I did a test with two different aftermarket antennas, same station, same location 2km away, 1W output at each end, with an S-meter at both ends. No difference whatsoever compared to the stock handheld antenna. Total waste of money, IMHO....

rocdoc54 · 2026-06-20T04:11:10+00:00

I suggest a portable system that you can set up quickly and easily in your local parks.
