Moonraker website. AT-5555 PLUSN – (New Version) Mobile 10M HF Transceiver In stock SKU 10-887

OK, my apologies. The Service Menu has the options to adjust / set the low and high dead-key carrier and those are the only two settings I adjusted. From what I have read, there are seven or eight clones of the 5555 and I can only assume that each clones has its own software program. My...

My neighbor has HS4 and we used the Service Menu for my AT-5555 Plus to set-up his radio. Have you accessed the Service Menu?

For those who are interested, this is a photo of the end cover identifying the two versions of the new version of the AT-5555 Plus and Plus N. I have not located a sources for the "N" version.

I agree. I purchased two 955HPC+ radios at the same time and both radios have been working great for one year. No mods on either radio and the Low Dead-Key is 1.5 watt and High Dead-Key is 8 watts. My friend bought one radio from me and we both have a 2-pill amp driving a 10-pill amp. We keep...

I had taken your advice and triple-checked all connections and identified the problem. My home-brew heavy-duty 10 gage power cord. I connected a six-inch piece of a standard 14/16 gage 12 volt power cord to a thirty-six inch piece of 10 gage wire with butt-connectors and the crimp onto...

From what I have read, the AnyTone 5555Plus (new version) and the Retevis HS4 are manufactured from the same "cookie cutter" and at the same bakery. The default value numbers in my new version AnyTone 5555Plus and my friend's Retevis HS4 are not exactly the same, but very close. AM Low and High...

The Quad5 Plus is my designated local radio matched-up with the Colossal 10K. I disconnected the amp and set the max RF power @ 6 watts with the RF Power at the full clockwise position.

Assuming the factory AM HP default value number on Menu #15 is 185, at the two o'clock position, the carrier would be approximately 10 watts. At twelve o'clock, the carrier would be approximately 6 watts.

For reference only. The factory default settings on my friend's HS4 and my AT-5555 Plus are; RF Power fully clockwise. Menu #15 / AM HP: Value #185 = 12 watt carrier. RF Power fully counterclockwise. Menu #16 / AM LP: Value #106 = 3 watt carrier. With RF Power fully clockwise, we set the AM...

Have you accessed the Service Menu to adjust the AM Low and High Power settings?

If you decide to venture-out and play (tinker) with the Service Menu, be certain to record the factory default settings / values prior to changing the values.

Superstar DM-507-4 is a "plug and play" microphone.

I'm using the basic Superstar DM-507-4 and I have the value set at 45 for the mic gain.

I have one and it was easy to convert. My friend has the clone, Retevis Ailunce HS4 and they have been working great.

I've tried a different radio with a two-watt carrier and I have the same problem. Definitely no defects with with jumpers, antenna and coax because my Stryker 955 works great with the same jumpers, antenna and coax.

I'v Yes, I use the "rule of thumb" formula, 25 watts per pill for the dead-key and reduce the formula by twenty-five percent. I have returned the 1 X 4 to the builder and requested to convert it to a straight 4 pill and install the components required for sideband delay.

Will the radio drive the 4-pill? 1.5 watt carrier = 20 PEP watts 4 watt carrier = 25 PEP watts 6 watt carrier = 40 PEP watts 10 watt carrier = 48 PEP watts
