Connex CX33HPC1 — Compact 10 Meter Amateur Mobile

The Connex CX33HPC1 is the short-chassis member of the Connex 3300 family, built for cabs, sleeper consoles, and dash cutouts where a full-size 10 meter mobile won't fit. It delivers the same 45 Watts PEP as the full-size Connex 3300HP but in a chassis that measures only 8 3/4" from bezel to rear — roughly 2.5" shorter than a 3300HP or CX3400HP — so it slides into overhead compartments and tight dash pockets on Class 8 trucks, work vans, and cab-over rigs.

Replacing a discontinued Connex CX3400HP? The CX33HPC1 is the compact-chassis successor — same 45W PEP output, same dual MOSFET finals, same front-panel 4-pin mic jack, and it adds AM/FM/PA (the CX3400HP was AM/FM only). At 8.75" long instead of the CX3400HP's 11.25", the CX33HPC1 fits tight overhead consoles and dash cutouts where a full-size 10m mobile won't go. A fresh mounting bracket is required because the chassis footprint is smaller. If you have the room and want the lower-priced full-size option that already includes a $60 Ranger SRA-198 microphone, look at the Connex 3300HP.

Who this radio is for

• Compact-install operators — sleeper consoles, overhead cutouts, van dashes, tractor cabs where the chassis has to be short.
• Amateur (10m) operators who want Connex power and clarity in a chassis that mounts where a Cobra or Uniden 4-pin CB would.
• Anyone replacing a discontinued CX3400HP that lived in a tight overhead — the CX33HPC1 drops in with a fresh mount at the same power level and adds FM.

Frequently asked questions

How is the CX33HPC1 different from the Connex 3300HP?

Both radios put out 45 Watts PEP with dual MOSFET finals. The 3300HP is the full-size chassis (about 11.25" long) and includes a $60 Ranger SRA-198 hand microphone in the box. The CX33HPC1 is the compact version at 8 3/4" long — the short chassis is the reason to pick it. It ships with a factory hand mic. If you have the room and want the lower price plus the upgraded stock mic, choose the 3300HP. If your install has less than about 10" of chassis depth (overhead consoles, tight dash cutouts), choose the CX33HPC1.

Will the CX33HPC1 replace my discontinued CX3400HP?

Yes — the CX33HPC1 is the compact-chassis successor to the CX3400HP. Same 45W PEP output, same dual MOSFET finals, same front-panel 4-pin mic jack, and it adds AM/FM/PA (the CX3400HP was AM/FM only). Because the chassis is 8 3/4" instead of 11 1/4", you will need a fresh mounting bracket — the old CX3400HP U-bracket footprint does not match. Your existing coax, antenna, mic, and power leads all carry over.

Does the CX33HPC1 work on FM?

Yes. The CX33HPC1 supports AM, FM, and PA modes through the six-band selector. This is one of the operational differences vs. the older CX3400HP, which was AM only.

What microphone plug does the CX33HPC1 use?

Standard 4-pin front-panel jack with Cobra-style wiring (Pin 1 ground, Pin 2 audio, Pin 3 TX, Pin 4 RX). Any 4-pin Cobra-pinout mic — including the Driver Extreme DRX-6560, Astatic 636L, or a President Bluetooth mic wired for 4-pin — will plug in directly.

Do I need an amateur radio license to operate the CX33HPC1?

The CX33HPC1 is a 10 meter amateur radio. Operating on the 10 meter amateur band in the United States requires a valid FCC amateur radio license (Technician class or higher).

Is the CX33HPC1 pre-tuned when it ships?

No. The CX33HPC1 ships in stock factory configuration. If you want it professionally aligned to the service-manual spec before it arrives, add the Pro tune and alignment option to your order at checkout.

Do you ship free?

Yes. The CX33HPC1 ships free to the US lower 48 and Washington DC.

What's included in the box?

Connex CX33HPC1 radio, factory hand microphone, mounting bracket and hardware, DC power cord, and owner's manual. Antenna, coax, mirror mount, and any upgraded microphone or speaker are sold separately (see the bundle links above for pre-packaged installs).
