- Comment on The official HAM frequency designation is between 144mhz and 148mhz. So why are transceivers, even the monobanders, able to work on a much wider range? 5 days ago:
Thanks for the explaination!
The other day I was checking out the datasheet for my Yaesu monobander’s final amp, and I noticed that it is able to performs optimally up to its advertised 80w only between 144mhz and 148mhz, while outside of that it’s capped to 60w. I’m pretty sure this is related to what you just explained.
Overall, I feel like the 2m band is like a kiddie playground, while the grownups are hanging out with their big antennas on HF.

What do you mean? Can you elaborate?

Perhaps it’s a regional thing. It is quite the wilde west where I’m from after all.
For the Yaesu FT-2900R, I indeed acquired this second hand, but I also got myself a new old stock FT-60R that seems to be able to transmit outside the HAM band for both 2m and 70cm out-of-box.

I have a few monobanders by Yaesu & Icom, and all of them are able to ony only Rx but also Tx outside of the HAM freqs. Of course, I’d be very careful with them 😇

- Comment on Yaesu FT-2900R Getting Lower Voltage Than Supplied 6 days ago:
Update: I accidentally shorted some component’s pins and the it failed to deliver the specified power once again. Guess now I know what happened to the old component I replaced. Luckily I have a spare.

Update: I decided to get myself a linear power supply. The issue persists. Therefore, it’s not power supply issue. The good news is, I now have no issue transmitting at full 75w power.

That is exactly right.

Update: The correct part has arrived. After replacing it, no more voltage drop!
- Comment on Yaesu FT-2900R Getting Lower Voltage Than Supplied 3 weeks ago:
Update: After inspecting the components’ voltages across the circuit and cross-checking it with the service manual, I found one of the transistors, marked Q1008 in the diagram, might be out of spec. The component should’ve been 2SJ615. Who knows what the phony seller did to it, but it was outputing well below the specified 13.5-13.8V (yes, I made sure the input was correct).

The power supply is rated for 360 watt, but who knows, it is a cheap chinese product after all.

That’s a ham indeed…
What do you usually find on that weekly net?

Funny that what got me here was actually the occasional difficulty of reaching folks in the other cars during road trips.
How far can you reach with that 2m HT?
Where I’m from, the license-free HT operation is in a specific UHF range with low power, which I have very little faith on.
