Newbie Alert - On the field testing before buying

#1434 Hello! I am about to buy a PRC2200 and I am preparing averything. I will test it this evening. What should I look for? Can the radio work at 12V normally? Just in case I have built a psu connector with RCA’s (following the advise on the group) to see if I can connect my normal PSU to i Looks like the unit has been bought in Germany 15ED2D71-867F-457B-9657-10630B28588B.jpeg |

#1435 Cesar, The best possible test would be to arrange a QSO with a friend. You want to see the radio turn on without any fault indications, have good sensitivity and clarity receiving a known station, and good transmit audio to your friend. The switches, knobs and buttons should operate properly. While the battery you suggest will work as a memory hold up battery, the set is designed to use a lithium thionyl chloride primary battery and that is what I would recommend. These are commonly available and inexpensive. Get one with leads attached as you should not solder directly to any lithium cell. The radio can be powered from a "12 volt" power supply. However, be very careful about polarity and note that on transmit the radio sends an initial tone at high power which can cause a voltage drop in the leads which will cause a transmit fault or radio reboot. When I run these on the bench I set my power supply to 14.4 volts which gives some margin and is consistent with a fully charged battery. I no longer use NiCd batteries, instead have gone over to lithium ion phosphate. I made my own in old battery cases but it was a bunch of work and you can buy a Bioenno pack that has plenty of capacity and just use it. I attached a photo which includes the bracket I made to connect to the battery pins. This is designed to be mechanically impossible to connect backwards. Make sure to tell Bioenno you are using the battery for this radio as the new versions of this module include an extra stiffener internally which you do not want.

#1437 Hi All! I use a SAFT LS 14500 if my memory serves me correct. 73 All PRC2200 users! /Morgan, SM6OID Från: PRC-2200@groups.io [mailto:PRC-2200@groups.io] För Lutz via groups.io Any non recharable backup lithium battery 3.6V is fine. Mechanical size "AA" 50*15 mm |

#1438 .... and after changing the backup battery, it could (but must not) happen, that you have to reset the rig, sometimes more than one time. |

#1440 ..."that you have to reset the rig..." by reset means the position of the knob on ERS or other function? tks |
Lutz
#1442 Right, pull the knob and turn to "ERS". |

#1446 Update. Looks like the rear antenna connector and the whip are not working. They do receive, but no ATU action. When i set the front antenna ok, then the ATU works finw and it transmits ok. Thank you |

#1447 Hi! I would try performing a BITE test while transmitting. This is described in the manual. I would expect “FAIL” as a result, then read fault codes. My guess is that the ATU is the problem, but you probably already guessed that. 73! /Morgan, SM6OID Från: PRC-2200@groups.io [mailto:PRC-2200@groups.io] För Cesar via groups.io Update.

#1449 Hello! I did it but looks like that it was not properly performed. I repeated it and now it says FAIL 76
What is modul cp (*) ? |
Erik Finskas OH2LAK
#1450 My guess is that CP refers to the antenna coupler module CP-2003. 73, Erik OH2LAK toggle quoted messageShow quoted text On Tue, 24 Jan 2023 at 11:17, Cesar via groups.io <Cesarleon=me.com@groups.io> wrote:

#1452 But tuner works using the front connector… is therr anything else I can do? pictured of the actual modules in the Tuner boards this is the board where the eeprom goes… no signs of it being messed around

#1453 The front panel rf connector is for connection to an external device such as a power amplifier. It does not use the Antenna Coupler which only tunes the whip antenna and dipole ports. Fred K6KKO …. |

#1454 At this point, do you think that a new ATU unit would soove the problem? Are they dully interchangeable between sifferent units? |

#1462 Ok! So now I have a new tuner unit. Same problem. This is a nightmare the bit test error on tx is the same: 76 |
